WRKY24 — Brassica juncea

Summary

BJUA03G39930S (BjWRKY33, also known as WRKY24) on chromosome A03 of Indian mustard encodes a WRKY-domain transcription factor with DNA-binding, calmodulin-binding, and protein kinase activities, and is annotated as a transcriptional co-regulator. The gene is associated with diverse biological processes including jasmonic acid and ethylene-dependent systemic resistance, salicylic acid-mediated signaling, abscisic acid-mediated stomatal movement, camalexin anabolism, cellular thermotolerance, and positive regulation of leaf senescence and autophagy. It is linked to traits such as drought tolerance, water use efficiency, cadmium concentration, aluminum response, disease tolerance, flowering time, seed growth and development, and root morphology. The 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 stomatal immunity.
