WRKY33 — Brassica napus

Summary

BnWRKY33 (DARMORV10_C03P25210.1) on chromosome C03 of oilseed rape encodes a protein containing a WRKY DNA-binding domain. The protein possesses sequence-specific DNA binding, transcriptional co-regulator, calmodulin binding, and protein kinase activities. BnWRKY33 is associated with jasmonic acid/ethylene-dependent systemic resistance, salicylic acid-mediated signaling, camalexin anabolism, cellular thermotolerance, abscisic acid-mediated signalling involved in stomatal movement, and male meiosis cytokinesis. It localizes to the nucleus, cytoplasm, mitochondria, and cell plate. The gene is linked to disease tolerance, salt tolerance, cadmium concentration, aluminum response, leaf senescence, flowering time, seed growth and development, and root morphology. Studies of related genes in other species connect the family to pathogen resistance, camalexin production, MAP kinase signaling, and drought stress response.
