WRKY43 — Cucumis sativus

Summary

CsWRKY43 (CSA_2G297180) on cucumber chromosome 2 encodes a WRKY-domain transcription factor with DNA-binding, calmodulin-binding, calcium-binding, and protein homodimerization activities. It is associated with regulation of salicylic acid metabolism, the antifungal innate immune response, abscisic-acid-mediated stomatal movement, gibberellin metabolism, leaf senescence, lignin biosynthesis, and responses to chitin and bacterial molecules. The gene has been linked to traits including callus induction, auxin and jasmonic acid content, leaf shape, root meristem development, stomatal closure time, seed germination under abiotic stress, cold stress tolerance, and resistance to Botrytis cinerea. Studies of related genes in other species connect the family to systemic acquired resistance, secondary metabolite production, salt stress tolerance, and root meristem regulation.
