WRKY3 — Brassica oleracea var. botrytis

Summary

BoWRKY3, located on chromosome 7 of cauliflower (Brassica oleracea var. botrytis), encodes a WRKY transcription factor characterized by a WRKY DNA-binding domain and promoter-specific chromatin binding activity. It is associated with regulation of antifungal innate immune response, response to chitin, response to fungi, and positive regulation of leaf senescence. The gene is linked to abscisic acid and gibberellic acid signaling, including abscisic acid mediated signalling involved in stomatal movement and downregulation of these pathways, as well as heat acclimation, salinity response, and response to jasmonic acid. It localizes to the nucleus, cytosol, and cytoplasm. Associations with plant growth and development trait, oxidative stress response, abscisic acid sensitivity, and salt tolerance have been noted. Studies of related genes in other species link the family to salt stress tolerance, methyl jasmonate stress tolerance, basal immunity, and thermo-resilience.
