NPR1 — Brassica juncea

Summary

BJUB06G26950S (BjNPR3) on chromosome B06 of Indian mustard encodes a transcriptional co-regulator with salicylic acid binding, calmodulin binding, DNA binding, and hydrolase activity, belonging to the NPR family with BTB/POZ and Znf_C2HC_NPR-type domains. It is associated with regulation of systemic acquired resistance, salicylic acid and jasmonic acid mediated signaling pathways, defense responses to bacteria, insects, and herbivores, as well as responses to hypoxia, xenobiotic stimuli, and extracellular ATP signaling. The gene is linked to traits including bacterial blight disease resistance, drought sensitivity, water use efficiency, leaf and root development, panicle length, and responses to various fungal diseases such as Cercospora leaf spot, wheat stripe rust, and rice sheath blight. Related genes in other species connect the family to pathogen resistance, cold tolerance, and thermotolerance.
