WRKY3 — Brassica oleracea var. botrytis

Summary

BoWRKY3, encoded by gene BOLND125_C02P063730.1 on cauliflower chromosome 2, is a WRKY-domain transcription factor with sequence-specific DNA binding and protein homodimerization activity. It is associated with the regulation of antifungal innate immune responses, responses to chitin, fungi, jasmonic acid, and gibberellin, as well as abscisic acid-mediated signalling in stomatal movement and positive regulation of leaf senescence. The gene has been connected to heat acclimation, salinity response, and oxidative stress response, and to traits including abscisic acid sensitivity, salt tolerance, and resistance to necrotrophic pathogens. Its product localizes to the nucleus, cytosol, and cytoplasm. Studies of related genes in other species link the family to salt stress tolerance, methyl jasmonate stress tolerance, basal immunity, and thermo-resilience.
