WRKY33 — Brassica oleracea

Summary

BoWRKY33 (BOLC102_C03P026730.1) on cabbage chromosome 3 encodes a WRKY-domain transcription factor with DNA-binding, calmodulin-binding, and protein kinase activities, and is annotated as a transcriptional co-regulator. It is associated with jasmonic acid/ethylene-dependent systemic resistance, salicylic acid-mediated signaling, camalexin anabolism, and positive regulation of leaf senescence and autophagy. The gene is linked to responses to light, carbon dioxide, hypotonic salinity, abscisic acid-mediated signalling involved in stomatal movement, and cellular thermotolerance. It localizes to the nucleus, cytoplasm, mitochondria, and cell plate. Associations with agronomic traits include cadmium concentration, aluminum response, low-temperature stress, disease tolerance, salt tolerance, flowering time, seed growth and development, root morphology, and leaf senescence. Studies of related genes in other species link the family to pathogen resistance, camalexin production, MAP kinase signaling, and drought stress response.
