WRKY24 — Brassica juncea

Summary

BJUB06G51800S (BjWRKY33, also known as WRKY24) encodes a WRKY-domain transcription factor with DNA-binding, calmodulin-binding, and protein kinase activities, and functions as a transcriptional co-regulator. In Indian mustard, this gene is associated with diverse processes including jasmonic acid/ethylene-dependent systemic resistance, salicylic acid-mediated signaling, camalexin anabolism, cellular thermotolerance, abscisic acid-mediated signalling involved in stomatal movement, and positive regulation of leaf senescence. It has been linked to traits such as drought tolerance, water use efficiency, cadmium concentration, aluminum response trait, flowering time trait, seed growth and development trait, and disease tolerance. The encoded protein localizes to the nucleus, cytoplasm, mitochondria, and cell plate. Studies of related genes in other species connect the family to pathogen resistance, camalexin production, MAP kinase signaling, and responses to drought, salt, and heavy metal stress.
