NIM1 — Brassica juncea

Summary

BJUA09G58380S (BjNIM1) on chromosome A09 of Indian mustard encodes a transcriptional co-regulator with salicylic acid binding, oxidoreductase, and calmodulin binding activities, containing BTB/POZ, ankyrin repeat, and NPR1/NIM1-like domains. It is associated with regulation of systemic acquired resistance, salicylic acid-mediated signaling, defense responses to bacteria, insects, and herbivores, as well as responses to pH, xenobiotics, and red/far-red light. The gene is linked to traits including bacterial blight disease resistance, drought sensitivity, photosynthetic rate, water use efficiency, panicle length, and iron content. It localizes to the nucleus, plasma membrane, plasmodesmata, and stress granules. Related genes in other species are associated with pathogen resistance, systemic acquired resistance, and salicylic acid-responsive gene expression.
