WRKY33 — Brassica napus

Summary

BnWRKY33 (DARMORV10_A04P29420.1) on chromosome A04 of oilseed rape encodes a WRKY transcription factor containing the conserved WRKY DNA-binding domain. The protein is annotated as a sequence-specific DNA-binding transcription co-regulator with calmodulin-binding, protein kinase, and homodimerization activities. BnWRKY33 is associated with diverse biological processes including jasmonic acid and ethylene-dependent systemic resistance, salicylic acid-mediated signaling, camalexin anabolism, cellular thermotolerance, abscisic acid-mediated signaling involved in stomatal movement, and male meiosis cytokinesis. It localizes to the nucleus, cytoplasm, mitochondria, and cell plate. The gene is linked to agronomically important traits such as disease tolerance, salt tolerance, cadmium concentration, aluminum response, flowering time, seed growth and development, leaf senescence, root morphology, and stomatal closure. Studies of related genes in other species connect it to pathogen defense, camalexin production, MAP kinase signaling, and drought stress response.
