Solutions !
• Get involved in the community curation• Provide details as much as possible in your
publications• Work with your species specififc database (if
available*) before/after publication on making sure data from your publication is integrated.– * If not available contact archives, succh as NCBI,
Uniprot, Gramene.• You need it, I need it, community needs it.
