NPR1 — Brassica juncea

Summary

BJUA01G29370S (BjNPR2, also known as NPR1) on chromosome A01 of Indian mustard (Brassica juncea) encodes a protein containing BTB/POZ, ankyrin repeat, and NPR1/NIM1-like C domains, with transcription cis-regulatory region binding, zinc binding, and protein binding molecular functions. 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, floral organ abscission, nodulation, leaf and flower development, stipule development, nuclear import, and responses to thirst and salinity. It localises to the nucleus, cytoplasm, nuclear body, and plasmalemma. Associations with plant height, panicle length, leaf length, water use efficiency, and drought tolerance have been noted. Related genes in other species are linked to bacterial disease response.
