NPR1 — Brassica juncea

Summary

BJUB05G53310S (BjNPR2, also known as NPR1) on Indian mustard chromosome B05 encodes a protein with a BTB/POZ domain, ankyrin repeats, and a NPR1/NIM1-like C-terminal region, characteristic of the NPR family. The product binds cis-regulatory DNA, homodimerizes, binds zinc and other proteins, and localizes to the nucleus, cytoplasm, plasma membrane and nuclear bodies. BjNPR2 is associated with systemic acquired resistance, salicylic acid- and jasmonic acid-mediated signaling, induced systemic resistance, defence responses to bacteria and fungi, response to herbivores, nodulation, floral organ abscission, stipule development, plant organ development, nuclear import, and responses to salinity and thirst. It is also linked to traits including drought tolerance, water use efficiency, plant height, panicle length, and leaf length. Related genes in other species are linked to bacterial disease response.
