NPR1 — Capsicum annuum

Summary

CaNPR3 (T459_19502) on pepper chromosome 7 encodes a regulatory protein of the NPR family, containing BTB/POZ, ankyrin repeat and zinc-finger domains, and binds transcription cis-regulatory regions and zinc. It is associated with the regulation of salicylic acid- and jasmonic acid-mediated signaling pathways, systemic acquired resistance, induced systemic resistance, defence responses to bacteria and herbivores, cell death, floral organ abscission, nodulation, and virus-induced PTGS. The protein localises to the nucleus, cytoplasm, plasmalemma and nuclear body. CaNPR3 is linked to photosynthetic rate and, through related genes in other species, to traits including disease resistance, drought tolerance, water use efficiency, chlorophyll content, root and stem growth, and nitrogen and protein content, as well as resistance to bacterial wilt, bacterial leaf spot and Botrytis cinerea.
