Title: Endophytic Streptomyces spp.: Characterization, antagonistic activity against Pythium
myriotylum and plant growth promoting potential on cocoyam tissue culture plantlets
Peguy Flora Djuidje Kouomo | Biotechnology Center of University of Yaounde, Canada
Abstract:
Background: Pythium myriotylum is the most devastating pathogen of cocoyam. Chemical control method
based on utilization of pesticides is mostly used. However, this method presents a range of negative side
effects such as environmental pollution, detrimental health effects for farmers and consumers, and the risk of
emergence of resistant pathogen strains. In view of these serious drawbacks, an alternative method using
antagonistic microorganisms is necessary. Actinobacteria have been known to produce antimicrobial and
plant growth promoting metabolites. Objectives: The aim of this study was to characterize and evaluate
endophytic Streptomyces spp. isolated from healthy cocoyam roots taken in Cameroon for antagonistic
activity and plant growth promotion. Materials and Methods: PERM2 isolated from cocoyam root was
characterized based on morphological, cultural, electron scan microscopy and identified using gene 16S
rDNA. Its antagonistic activity against P. myriotylum was evaluated using dual culture assay and ability to
produce cell wall degrading enzymes according to the relevant protocols.
Otherwise, its ability to produce plant growth promoting attributes and its effect on cocoyam tissue culture
plantlets was evaluated. Results: Morphological, cultural characterization, 16S rDNA gene sequencing and
phylogenetic analysis suggested that isolate PERM2, belongs to Streptomyces genus. Dual culture assay
revealed that PERM2 highly inhibited the mycelial growth of P. myriotylum in vitro with the inhibition
percentage of 99.38%. Biochemical characterization indicated that PERM2 was positive for urea, catalase,
starch, gelatin and lytic enzymes such as chitinase, β-1,3-glucanase, protease, lipase, cellulase and pectinase.
PERM2 was also able to show plant growth promoting traits. Streptomyces sp. PERM2 increased
significantly length, fresh weight and number of secondary roots compare to control. Conclusion: These
results suggest that Streptomyces sp. PERM2 could be a potential biocontrol and PGP agent to be used for the
development of biopesticide and biofertilizer for a sustainable agriculture.
Title: Effect of elicitors on metabolite production in cell suspensions of Piper cumanense
(Piperaceae)
Laura Rodríguez-Sánchez | Universidad Nacional de Colombia, Colombia
Abstract:
Plant secondary metabolites represent a wide variety of compounds with essential ecological roles. Moreover,
some of them are important in food, pharmaceutic and agriculture industries due to their applications as
flavoring, for treatment of diseases, and pest control. Although research in this field have increased in the last
years, it has been difficult to develop and extend more applications due to the low amounts of metabolites
produced by plants. Plant biotechnology appears as a valuable strategy for increasing production of
compounds of interest. Piper cumanense is a neotropical shrub that produces benzoic acid derivates with
promising bioactivity for control of phytopathogenic fungi. However, these compounds have been isolated
with low extraction yields being necessary to evaluate strategies that could increase their production. The
purpose of this study was to evaluate the effect of the elicitors methyl jasmonate and salicylic acid on
activation of secondary metabolic pathways on cell suspensions of P. cumanense. Cell suspensions were
established from friable callus in M&S liquid medium adding a combination of 2,4-D 1,0 mg/L and BAP 0,5
mg/L, thiamine 1 mg/L, myo-inositol 100 mg/L and sucrose 30 g/L. Fifteen days after growing, two
concentrations of MeJA and SA (10 and 100 µM) were separately added to cell suspensions. The effect of
elicitors was evaluated in three different exposure times (6h, 12h and 24h). Suspensions were harvested using
vacuum filtration and metabolites were extracted in ethyl acetate. Metabolic profiles of samples were obtained
by GC–MS and analyzed using multivariate statistical methods. The analysis revealed important differences
in profiles related to type of elicitor, concentration and exposure time. The elicitation induced secondary
metabolites production in cell suspensions treated. This research represents an important advance in the
development of strategies that could increase metabolites of interest in cell suspensions of P. cumanense.
Title: About the Nature of Climatic Oscillations
Alexander A. Ivlev | Russian State Agrarian University – MSKhA of K. A. Timiryazev, Russia
Abstract:
In the recently developed concept of global carbon turnover it was shown that the evolution of the global
carbon cycle and the biosphere took place on the background of alternating orogenic cycles, which were the
result of the interaction of continuously moving lithospheric plates and photosynthesis. At the same time, the
existence of short-term cycles, called climatic oscillations, was noted. Their duration was more than an order
of magnitude less and they covered a limited area. Analysis of the features of climatic oscillations showed that
they are very similar to the features of orogenic cycles. Just like orogenic cycles, climatic oscillations
emerged during periods of intense volcanic and magmatic activity and sea level rise. As well as orogenic
cycles, climatic oscillations had two phases : the "greenhouse effect" phase and successive phase of cooling.
The phase of "greenhouse effect" was characterized by an increase in temperature and anaerobic (low-
oxygen) environment. The cooling phase was associated with a decrease in CO2 concentration and with an
increase in O2 concentration. Climatic oscillations caused biotic turnovers, which have been ending with mass
extinctions of organisms. Accordingly, they have been accompanying by the appearance of sedimentary rocks
rich in organic matter. Other characteristics, such as carbon isotope characteristics of organic matterhas been
changing similarly. The similarity of characteristics allows us assuming the same nature of orogenic cycles
and climatic oscillations. Indeed, the orogenic cycles are linked to the uneven movement of lithospheric plates
due to convective flows in magma caused by the gravitational interactions of the Earth with celestial bodies.
We hypothesized that there are weaker gravitational interactions caused, for example, by periodic inclination
of the orbit plane and by the changes in orbit eccentricity.
Title: Foliar Application of Salicylic Acid and Glycine Betaine improve Antioxidant Enzymes and
Biochemical Characteristics of Potato Cultivars under Water Deficit
Mouhamad Alhoshan | Researcher in the General commission for scientific agriculture
research
Abstract:
This pot experiment was conducted to evaluate the response of potato plants to water deficit and foliar
application of salicylic acid (SA) and glycine betaine (GB). Four potato cultivars were grown in pots and
subjected to two irrigation regimes (30 and 60% depletion of available soil water) and two independent levels
of both SA (0.5 and 1.0 mM) and GB (1.0 and 2.0 mM) in addition to the control treatment (0.0 mM SA and
GB). Activities of superoxide dismutase (SOD), catalase (CAT), peroxidase (POX), proline content,
photosynthesis, total chlorophyll, carotenoid along with plant dry mass (PDM) and tuber yield (TY) were
measured. Water deficit significant effects on all traits. Drought tolerance was determined as increasing in
antioxidant enzymes, proline content and by calculating the stress susceptibility index (SSI). As well as,
drought tolerant cultivars (Spirit and Born) revealed higher accumulation of proline content, carotenoid and
antioxidant enzymes activities. Also, the maximum values of SSI were observed in tolerant cultivars.
However, foliar applied SA and GB affected the activities of antioxidant enzymes and increased proline
content, photosynthesis, chlorophyll pigments, PDM and TY. The range of the increases seemed greater when
potato cultivars were grown under water deficit conditions. All the above effects aided the PDM and TY of
potato cultivars to increase by increasing SA and GB in most levels and led to the supposition that external
spray of SA and GB could be improved the growth and enabled potato cultivars to withstand water deficit.
Also, under 60% depletion of available soil water, the SA effects was clearer on all traits as compared with
their controls and applied GB.
Title: Identification and analysis of MAPKs and miRNAs in IR56 rice in response to compatible
and incompatible BPH infestations
Satyabrata Nanda | State Key Laboratory of Rice Biology, China
Abstract:
The brown planthopper (Nilaparvata lugens Stål, BPH) is one of the most dreadful pest of rice challenging its
production and sustainability. Therefore, understanding the rice-BPH interactions and their underlying
mechanisms are of high interest. Rice mitogen-activated protein kinases (MAPK) and microRNAs (miRNA)
have been reported to be involved in stress responses, including pest attacks. In this study, the comprehensive
analysis of the MAPKs and miRNAs in the IR56 rice (containing a BPH-resistant gene Bph3) in response to
separate BPH infestations of varied virulence levels identified the BPH-responsive MAPKs and miRNAs. The
interaction between IR56 rice and IR56-BPH (virulent BPH population established on IR56 rice) is
considered to be compatible, whereas the interaction between IR56 rice and TN1-BPH (avriulent BPH
population established on TN1 rice) is considered to be incompatible in nature. Out of 17 MAPKs in IR56
rice, 5 OsMPKs (OsMPK1, OsMPK3, OsMPK7, OsMPK14, and OsMPK16) were found to exhibit
upregulated expressions exclusive to the incompatible rice-BPH interactions, whereas 6 OsMPKs (OsMPK4,
OsMPK5, OsMPK8, OsMPK9, OsMPK12, and OsMPK13) were associated with both incompatible and
compatible interactions. The transcription analysis of salicylic acid, jasmonic acid, and ethylene
phytohormone signaling genes revealed their roles during the rice-BPH interactions. The upregulated
expression of OsC4H, OsCHS, and OsCHI in the incompatible interaction implied the potential defense
regulatory roles of phenylpropanoids. Further, the elevated transcript accumulations of OsGST and OsSOD,
and the increased enzyme activities of POD, SOD, and GST at 1 day post-infestation (dpi), but not at 3 dpi,
indicated that reactive oxygen species (ROS) signaling might be an early event in rice-BPH interactions. In
addition, the upregulated transcription of OsLecRK3 and OsLecRK4 was found only during an incompatible
interaction, suggesting their involvement in the BPH resistance response in the IR56 rice variety.
Title: Effect of Organic and chemical Fertilization on growth and yield seeds of fennel
(Foeniculum vulgare L.) And it's active ingredients
Dler J. Ramzan sulaivani | Duhok Polytechnic University
Abstract:

Title: Ecological Conditions and Species Diversity of Sundarbans Mangrove Forest
A.K.M. Nazrul Islam| Dhaka University
Abstract:
There are about 16 million mangrove forest in the world. Mangrove ecosystems have wide diversity of plant
species (Field 1996). The Sundarbans mangrove forest of Bangladesh is one of the single largest tracts in the
world and is situated in south west corner of the country (latitude 210.32 – 220.31’ N and longitude 890.0 to
900.1 E). The total forest area is 577,220 ha including river channels and other water courses. Plant
communities occupy approximately 401,600 ha. (Chaffey et al. 1985). Dominant plant species in the low
lying areas are Nypa fruticans, Acanthus ilicifolius, Phrgmites karka, Porteresia coarctata,Typha elephantina
and Sonneratia apetala. Soil physicochemical properties and plant community and diversity were evaluated
(Nazrul Islam 1995; 2015). The present paper explains in a nutshell the ecological conditions and plant
diversity. Soil and water samples were collected from the various ecological zones in different seasons.
Mehods : Soils were extracted for exchangeable cations (Gupta and Rorison 1974, Nazrul-Islam and Rorison
1978). Calcium and magnesium were determined by atomic absorption spectrophotometry; sodium and
potassium were analysed by the flame photometer; electrical conductivity was determined by a conductance
bridge (Griffin & Company); chloride and other ions in water samples were determined according to standard
methods of the American Public Health Association (1977).
Title: Evaluating the Fungicidal Effect of Bacterial Isolates in Infested Plant Species
Asia Nosheen | COMSATS University
Abstract:
Increase in the human population, gradual change in climate, decrease in land availability and enormous
weather conditions decreased the production of cereals and grains. To meet the current demand of food,
fertilizers, pesticides and fungicides are used but they pose a major threat to human health and environmental
pollution. The current study was performed to evaluate the antifungal and biocontrol potential of
Lactobacillus Rhamnosus and Weissella Confusa in basmati rice against Rhizoctonia Solani. The agar disc
method was performed to evaluate the antifungal activity of Lactobacillus Rhamnosus and Weissella Confusa
against Rhizoctonia Solani. Pot and petri plate experiments were conducted to evaluate the potential of
Lactobacillus Rhamnosus and Weissella Confusa to promote growth of basmati rice and to evaluate the
biocontrol potential of Lactobacillus Rhamnosus and Weissella Confusa in basmati rice under Rhizoctonia
Solani stress. Maximum antifungal activity was recorded by Lactobacillus Rhamnosus against Rhizoctonia
Solani. In petri plate experiment, the maximum root length was shown by Weissella Confusa and maximum
shoot length was shown by Lactobacillus Rhamnosus. In pot experiment, Lactobacillus Rhamnosus treatment
showed the enhanced growth of basmati rice. The treatment Lactobacillus Rhamnosus + Rhizoctonia Solani
showed the increase in proline and sugar content. The plant defense enzyme SOD, POD, CAT, PPO and PAL
was recorded maximum in the treatment Weissella Confusa + Rhizoctonia Solani except the PPO activity that
was shown higher in Lactobacillus Rhamnosus Control. The Lactobacillus Rhamnosus showed the best
results in basmati rice growth and Weissella Confusa showed the best results in protecting the basmati rice
against Rhizoctonia Solani and can be suggested as potent biocontrol agents.
Title: The uniformly vegetative states and their linear stability in isotropic environmental
conditions: the case of vegetation spirals and arcs
Maroua Messaoudi | Université Moulay Ismail
Abstract:
We present a generic interaction-redistribution model on facilitative and the competitive interactions
between individual plants responsible for the formation of periodic vegetation patterns.
Material and methods: To study the formation mechanisms of plant communities we based on a generic
interaction-redistribution model, which includes the competition and facilitation interactions between
individual plants. We predict theoretically the diameter of a single patch grows in the course of t ime until
it reaches a critical size over which the self-replication phenomenon takes place, leading to the
fragmentation or the circulation of the tufts. This process continues until the system reaches a self-
organized vegetation pattern.
Results and discussions: The kinetic equation governing the evolution of the biomass density b(r,t) at
time t and point r is written in the following form
bt (x, t) = F1 × F2- F3, (1)
Where the first term F1 × F2 of the right-hand side is the growth term; the second term of equation (1)
models the spontaneous or induced death of plants, it expresses the rate at which vegetation density
decreases.
Title: Isolation and Identification of endophytic fungi from Mangrove Rhizophora sp
Ravimannan N | University of Jaffna
Abstract:
Mangroves grow in the intertidal zone where there is high salinity. Previous studies have shown that
mangroves are rich sources of endophytic fungi. Researchers have found that mangrove fungi are important to
mangroves which are adapted to the extreme environmental conditions and suggest that they are potential
sources for screening of new products. In the present study, four different species of Aspergillus sp were
isolated from the mangrove Rhizophora sp. They were morphologically different and had different cultural
characteristics.
Further research should be carried out at molecular level to confirm the isolated Aspergillus sp at species
level.
Title: Green Vaccination: Smart Plant Health Care for Human Welfare
Prashant Singh | University of Rajasthan
Abstract:
One of the biggest challenges for food security in the 21st century is to improve crop yield stability through
the development of disease-resistant crops. Plants are constantly exposed to potentially pathogenic microbes
present in their surrounding environment. Population burst, loss of agricultural land due to climate change,
erosion and lack of water require that we reduce production losses such as those caused by pest and pathogens
as much as possible. As a result, biotic stress, a loss of fitness caused to an individual by other organisms
places a major constraint on plant growth.
In the absence of genetic resistance in crops, food production heavily depends on use of chemical to control
pathogens. Despite their effectiveness, chemicals-based plant defense has detrimental environmental
consequences and creating risks to the wider environment. Modern synthetic chemicals usually have reduced
environmental toxicity; however, they are expensive and only available to advanced agricultural production
systems. Moreover, as with antibiotics, discovery of new chemical to control plant disease is difficult and
extensive use of current agents may result in selection of pathogen strains tolerant to pesticides.
Reducing the dependence of food production on chemical control is a key goal of plant pathology research.
One of the major goals of plant research in the 21st century is to increase our understanding of the plant
defense system and unravel how this is manipulated by pathogens, in order to engineer crops with both
durable resistance against pathogens and increased yields.
Plants have evolved a sophisticated immune system to resist pests and diseases. Apart from their innate
immune system controlling pre-programmed defense reactions, plants can also increase the responsiveness of
their immune system in response to selected environmental signals. This phenomenon is known as “defense
priming”.
Title: Wheat breeding for biotic and abiotic stresses tolerance at ICARDA targeting CWANA and
SSA regions
W. Tadesse | International Center for Agricultural Research in Dry Areas
Abstract:
Wheat production is highly affected by biotic and abiotic stresses at global level in general and in the Central
and West Asia and North Africa (CWANA) and Sub Saharan Africa (SSA) regions in particular. Associated
to climate change, heat and drought stresses are increasingly important resulting in reduction of
photosynthesis, pollen viability, grain number and weight, and hence lowering yield and quality of major
cereals and legumes crops. The wheat breeding program at ICARDA uses conventional and molecular
approaches such as the Focused Identification of Germplasm Strategy (FIGS), mega environments, shuttle
breeding, doubled haploids, marker-assisted selection, genomic selection, speed breeding and key location
phenotyping to develop elite genotypes with high yield potential and resistance to the major biotic and abiotic
stresses. Yield levels of the top yielding elite spring bread wheat genotypes ranged up to 6t/ha at Wadmedani
station of Sudan under extreme heat stress, 7t/ha at Merchouch station of Morocco under terminal moisture
stress (260 -300 mm) and 11 t/ha at Sids station in Egypt under optimum conditions. Genetic gain analysis
from 1980 to 2017 showed 2.5, 1.3 and 2.3%year -1 increment at Merchouch, Wadmedani and Sids stations,
respectively. Association mapping identified 14 associations related to grain yield on chromosomes 5B (4),
4B (3), 3B (2), 5A (2), 1B, 2B and 7B (1) under moisture stress. Significant MTAs for yield under heat stress
have been also identified through genome wide association mapping studies.
Title: Impact of agronomic practices on the development of wheat leaf blotches

traditional soil tillage with ploughing at the depth of 22–24 cm; A2 – reduced soil tillage with disc harrowing
up to the depth of 10 cm), and B – crop rotation (B1 – continuous wheat; B2 – oilseed rape and wheat; B3 –
crop rotation where barley and faba beans were included in addition to wheat and rape). Data obtained during
2012–2019 were analysed. Severity of leaf diseases was assessed every week, and the area under the disease
progress curve (AUDPC) was calculated. Tan spot caused by Pyrenophora tritici-repentis dominated during
the experimental period, and also Septoria leaf blotch caused by Zymoseptoria tritici was observed. Minimal
soil tillage significantly increased the development of tan spot but decreased the level of Septoria leaf blotch.
The level of tan spot was higher in continuous wheat sowings but similar in other variants. The inclusion of
faba beans and barley in the crop rotation scheme did not decrease the level of tan spot compared to the
variant where only oilseed rape and wheat were grown. Relationship between these two pathogens has to be
studied in future.

Title: Photopedogenesis, A Fundamental Soil Forming Process Associated with Soil-Light-
Rhizosphere Interface
Bipin B Mishra | Bihar Agricultural University
Abstract:
Sun light is not only the source of energy during pedogenesis, but works also as an active factor to stimulate
the weathering of rock in presence of moisture leading to soil formation under a sustainable management
strategy, such as regenerating farming or conservation agriculture. Photopedogenesis is a cumulative term
used for weathering of rock in presence of moisture due to emergence of phototrophic microbes and lichens
leading to soil development in time and space. Light radiation passes directly through moist soils since water
is a medium for light. In a simple classical experiment, sunlight was observed to move and penetrates the
moist soil (2 mm). Penetration of light into the moist soil (after reflection) undergoes either absorption or
transmittance or both. The fresh rock during rain (wetness) promotes the growth of lichen, phototrophs,
mosses, blue green algae forming mat, hyphae and root. The biomass so produced undergoes decomposition
and gradually helps in weathering of the rock surface, where contribution of light as well as moisture is vital.
In almost all known soil forming processes, horizonation begins at surface of the parent material forming “O”
horizon and subsequent A, B horizons over C horizon. The “O” horizon is the outcome of the contribution of
sunlight and moisture on rock or parent materials leading to humification.
Soil being the lowest boundary of earth’s atmosphere, interacts with incoming sun light as reflection,
absorption, scattering and transmittance, in which transmitted light is vital to further interact photochemically
to either in soil biofilm as well as in soil-rhizosphere interface, though the role of light radiation in the
existence of either biofilm or rhizosphere has been least understood and necessitates detailed investigation.
Theory of Photopedology was initially developed in 1996, which was subsequently improved to
Photopedogenesis in 2006 as being the fundamental soil forming process besides stabilizing the soil biofilm
and soil-rhizosphere interface. Two additional soil forming factors are proposed in the modern pedology.
Chandrayan 1 in India discovered signals for water on lunar surface
(https://images.app.goo.gl/8BNb2fRoj4MXHP1C6) having weatherable rocks (basalt) and minerals
(pyroxene). Photopedogenesis may be expanded on lunar or mars surface to understand the possibility of soil
genesis.
Title: Pistacia lentiscus: a plant with multiple virtues
Djebbar Atmani | University of Bejaia, Algeria
Abstract:
Medicinal plants are believed to be an important source for the discovery of potential antioxidant,
anticancer, anti-inflammatory and anti-diabetic substances. The present study was designed to investigate
the neuroprotective, anti-inflammatory, anti-diabetic and anti-hyperuricemic potential of Pistacia
lentiscus, as well as identification of active compounds, using appropriate methodology. Evaluation of
antioxidant activity was undertaken to support anti-inflammatory activity.
The antioxidant potential of plant extracts against known radicals was measured using various standard in
vitro methods. Anti-inflammatory activity was determined using the paw edema model in mice whereas
the anti-diabetic effect was assessed in vivo by streptozotocin (STZ)-induced diabetic rats and in vitro by
inhibition of alpha-amylase. Anti-inflammatory activity of plant extracts using in vitro assay was equally
evaluated by measuring the secretion of pro-inflammatory cytokine (Interleukin-1β) using ELISA kits.
Diuretic activity was assessed by measurement of urinary volume output and determination of electrolytes
(Na+ and K+), whereas neuroprotective activity was investigated using Aluminum-induced toxicity test.
Identification of phenolics was also carried out using HPLC-MS.
Pistacia lentiscus extracts and fractions exhibited high scavenging capacity against DPPH, NO. and ABTS+
radicals in a dose-dependent manner, with respective IC50 values of 4.6, 2.71 and 1.0µg/ml and restored blood
glucose levels, in vivo, to normal values, in agreement with the in vitro anti-diabetic effect (65% inhibition of
α-amylase). Oral administration of plant extracts significantly decreased (60% inhibition) carrageenan-
induced mice paw oedema, similar to the standard drug, diclofenac, was effective in reducing the serum levels
of IL-1β in cell culture and induced a significant increase in urinary volume in mice, associated to a promising
anti-hyperuricemic activity.
Title: Metabolomics of a resurrection plant during a complete dehydration/rehydration cycle.
Kjell Sergeant | Institute of Science and Technology, Luxembourg
Abstract:
A limited number of plant species have the capacity to undergo close-to-complete loss of water and recover
from this, Craterostigma plantagineum is such resurrection plant. In the frame of the current climate change
and the predicted higher frequency of drought, studies of the mechanisms by which C. plantagineum can
withstand drought can provide leads to improve the drought resistance of crops.
In addition to other analyses, the changes in the metabolite profile during a dehydration/rehydration cycle
were followed. Metabolites were extracted at different stages (fully hydrated, partially dehydrated, 2%
relative water content and 24 hours after rewatering) and analysed with both GC-MS (targeting amino acids
and mono-saccharides) and LC-MS for secondary metabolites.
In total about 150 metabolites that undergo a chance in abundance during the dehydration/rehydration cycle
were identified. Major known processes (accumulation of mono- and disaccharides, decreased abundance of
octulose, …) were confirmed by our data. Specific processes for which numerous compounds were identified
include the biosynthesis and degradation of chlorophyll.
However the bulk of the identified compounds is made up of lipids, with most lipid classes including
phophocholines and phosphoethanolamines having an increased abundance during dehydration.
Title: 2 Da, a small but significant difference
Kjell Sergeant | Institute of Science and Technology, Luxembourg
Abstract:
Although rare in natural proteins, α-β didehydroamino acids are essential components of numerous bioactive
peptides. They are furthermore intensively studied for their conformation-directing properties and in the
production of recombinant proteins with a custom-made fold.
While doing a study on the cell wall proteome of alfalfa stems, a mass shift of -2Da was observed on a
phenylalanine of the β-subunit of polygalacturonase (BPG). An observation confirmed by reanalysis of
datasets generated in-house or downloaded from proteomics repositories. The conclusion of these analyses is
that all identified phenylalanines in the sequence FxxY of the active BPG are modified by desaturation of the
alpha-beta carbon bond, resulting in didehydrophenylalanine (ΔPhe). The same modification was not
observed in any other protein, not from plants nor from animal or bacterial origin.
The known fold-determining properties of didehydroamino acids also give a clue on the functional
significance of this modification. The protein is inherently disordered without modification but known to
interact tightly with the catalytic subunit of polygalacturonase and pectin nonetheless. The repetitive
occurrence of ΔPhe might be the way by which the protein’s fold is stabilized to ensure these interactions.

Title: Screening Vitis Genotypes for Responses to Botrytis cinerea and Evaluation of Antioxidant Enzymes,
Reactive Oxygen Species and Jasmonic Acid in Resistant and Susceptible Hosts
Mati Ur Rahman | State Key Laboratory of Crop Stress Biology in Arid Areas, China.
Abstract:
Botrytis cinerea is a necrotrophic fungal phytopathogen with devastating effects on many Vitis genotypes.
Here, a screening of 81 Vitis genotypes for leaf resistance to B. cinerea revealed two highly resistant (HR),
twelve resistant (R), twenty-five susceptible (S) and forty-two highly susceptible (HS) genotypes. We focused
on the HR genotype, ‘Zi Qiu’ (Vitis davidii), and the HS genotype ‘Riesling’ (V. vinifera), to elucidate
mechanisms of host resistance and susceptibility against B. cinerea, using detached leaf assays. These
involved a comparison of fungal growth, reactive oxygen species (ROS) responses, jasmonic acid (JA) levels,
and changes in the anti-oxidative system between the two genotypes after inoculation with B. cinerea. Our
results indicated that the high-level resistance of ‘Zi Qiu’ can be attributed to insignificant fungal
development, low ROS production, timely elevation of anti-oxidative functions, and high JA levels.
Moreover, severe fungal infection of ‘Riesling’ and sustained ROS production coincided with relatively
unchanged anti-oxidative activity, as well as low JA levels. This study provides insights into B. cinerea
infection in grape, which can be valuable for breeders by providing information for selecting suitable
germplasm with enhanced disease resistance.
Title: Spatio-Temporal Analysis of Vegetation Dynamics as a Response to Climate Variability
and Drought Patterns in the Semiarid Region, Eritrea
Simon Measho | Institute of Geographic Sciences and Natural Resources Research, China
Abstract:
There is a growing concern over change in vegetation dynamics and drought patterns with the increasing
climate variability and warming trends in Africa, particularly in the semiarid regions of East Africa. Here,
several geospatial techniques and datasets were used to analyze the spatio-temporal vegetation dynamics in
response to climate (precipitation and temperature) and drought in Eritrea from 2000 to 2017. A pixel-based
trend analysis was performed, and a Pearson correlation coefficient was computed between vegetation indices
and climate variables. In addition, vegetation condition index (VCI) and standard precipitation index (SPI)
classifications were used to assess drought patterns in the country. The results demonstrated that there was a
decreasing NDVI (Normalized Difference Vegetation Index) slope at both annual and seasonal time scales
(Figure 1). In the study area, 57.1% of the pixels showed a decreasing annual NDVI trend, while the
significance was higher in South-Western Eritrea. In most of the agro-ecological zones, the shrublands and
croplands showed decreasing NDVI trends. About 87.16% of the study area had a positive correlation
between growing season NDVI and precipitation (39.34%, p < 0.05). The Gash Barka region of the country
showed the strongest and most significant correlations between NDVI and precipitation values. The specific
drought assessments based on VCI and SPI summarized that Eritrea had been exposed to recurrent droughts
of moderate to extreme conditions during the last 18 years. Based on the correlation analysis and drought
patterns, this study confirms that low precipitation was mainly attributed to the slowly declining vegetation
trends and increased drought conditions in the semi-arid region.
Title: Physiological and qualitative response of rice (Oryza sativa L.) to varying planting methods, sowing time and irrigation schedules Wasiq Ikram| Minhaj University Lahore
Abstract:
Crop management strategies that reduce ground water depletion and labour requirement, while maintaining
and enhancing crop yields are urgently needed in Pakistan, to grow more crops with efficient natural resource
management. Dry direct-seeded rice (DSR) has been proposed as one of the means in achieving these
objectives. However, optimal water management strategy for DSR is required to be devised with respect to
paddy yield as well as grain quality. Moreover planting time also affects crop growth, yield and quality.
Therefore field experiments were conducted to investigate the physiological and qualitative response of rice
(Oryza sativa L.) to varying planting methods, sowing time and irrigation schedules. The irrigation scheduling
was based on soil moisture conditions ranging from continuous flooding (CF) for transplanted rice (TPR) to
alternate wetting and drying (AWD) for DSR. Different growth, yield and qualitative parameters were
recorded to evaluate sowing window, planting methods and irrigation schedules using Basmati variety (Super
Basmati). The higher paddy yield was recorded in early planted (EP) DSR than TPR. Among different
irrigation schedules, 3 supplemental irrigations (SI) at reproductive stage in addition to AWD style resulted in
higher yield as compared to the other schedules. Under DSR, EP (mid June) produced enhanced crop growth
and yield than end June sowing. The DSR-AWD treatment improved water use efficiency with 17 % water
saving than TPR. Furthermore, DSR+AWD at reproductive stage resulted in higher leaf protein but less sugar
as compared to the other irrigation treatments.
