NPR1 — Brassica juncea

Summary

BJUB04G43750S (BjNPR3) encodes a transcriptional co-regulator with salicylic acid binding, calmodulin binding, DNA binding, and hydrolase activity, containing BTB/POZ, ankyrin repeat, and NPR1/NIM1-like domains. In Indian mustard, this gene is associated with regulation of systemic acquired resistance, salicylic acid and jasmonic acid mediated signaling pathways, defense responses to bacteria and herbivores, response to hypoxia, stipule development, floral organ abscission, and nuclear import. It localizes to the nucleus, cytoplasm, and plasma membrane. Associations with agronomic traits include bacterial blight disease resistance, drought sensitivity, leaf length, panicle length, stem senescence, water use efficiency, and responses to Cercospora leaf spot, wheat stripe rust, and rice sheath blight. Related genes in other species link it to pathogen resistance, cold tolerance, and thermotolerance.
