WRKY33 — Brassica napus

Summary

BnWRKY33 (DARMORV10_A03P21330.1) on chromosome A03 of oilseed rape encodes a protein containing the WRKY DNA-binding domain. The protein possesses sequence-specific DNA binding, transcriptional co-regulator, calmodulin binding, and protein kinase activities. It is associated with diverse biological processes including jasmonic acid/ethylene-dependent systemic resistance, salicylic acid-mediated signaling, camalexin anabolism, cellular thermotolerance, and regulation of stomatal movement. The gene has been linked to agronomically important traits such as disease tolerance, salt tolerance, cadmium concentration, flowering time, seed growth and development, leaf senescence, and root morphology. It localizes to the nucleus, cytoplasm, mitochondria, and cell plate. Studies of related genes in other species connect it to pathogen defense responses, camalexin production, MAP kinase signaling, and drought stress response.
