NPR1 — Brassica juncea

Summary

BJUB05G53290S (NPR1) on chromosome B05 of Indian mustard encodes a protein with a BTB/POZ domain, ankyrin repeats, and a C2HC-type zinc finger, and is annotated to transcription cis-regulatory region binding and zinc binding. The gene is associated with the regulation of salicylic-acid-mediated and jasmonic-acid-mediated signaling pathways, systemic acquired resistance, induced systemic resistance, defence responses to bacteria and fungi, and response to herbivore. It has also been connected to stipule, leaf, flower and plant organ development, floral organ abscission, nodulation, nuclear import, and responses to thirst and salinity. The product 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 link the family to systemic acquired resistance and salicylic acid signalling.
