NPR1 — Brassica juncea

Summary

BJUA01G29390S (NPR1) on chromosome A01 of Indian mustard encodes a transcription cis-regulatory region binding protein with zinc-binding activity, belonging to the NPR1/NIM1-like family and containing BTB/POZ, ankyrin repeat, and zinc finger domains. The gene is associated with regulation of salicylic acid- and jasmonic acid-mediated signaling pathways, systemic acquired resistance, induced systemic resistance, defence responses to bacteria and fungi, response to herbivore, and responses to salinity and thirst. It is also linked to nuclear import, stipule, leaf, flower, and plant organ development, floral organ abscission, nodulation, and regulation of DNA-templated transcription. The protein localizes to the nucleus, cytoplasm, nuclear body, and plasmalemma. Associations with agronomic traits include panicle length, leaf length, plant height, photosynthetic rate, water use efficiency, and drought tolerance. Studies of related genes in other species link the family to net photosynthetic rate, leaf water potential, transpiration rate, and stomatal resistance.
