WRKY53 — Brassica napus

Summary

BnWRKY53 (DARMORV10_A01P15120.1) on chromosome A01 encodes a WRKY-domain transcription factor with DNA-binding, transcription factor activity, and MEKK activity, along with calcium ion binding and protein serine/threonine kinase activity. In oilseed rape, this gene is associated with defense responses to nematodes, positive regulation of salicylic acid-mediated signaling, systemic acquired resistance, and regulation of jasmonic acid signaling. It is linked to glucosinolate breakdown, glutathione metabolism, MAPK cascades, root meristem growth, and responses to ozone, water deprivation, and mechanical stimuli. Associations include leaf chlorosis, plant height, flowering time, seed development, aluminum response, salt tolerance, insect and pathogen resistance, and temperature stress responses. Studies of related genes in other species link the family to glucosinolate hydrolysis, immune response, and stress signaling.
