NIM1 — Capsicum annuum

Summary

T459_19751 (CaNIM1) on pepper chromosome 7 encodes a regulatory protein of the NPR family, possessing oxidoreductase activity acting on a sulfur group of donors with disulfide as acceptor, salicylic acid binding, calmodulin binding, and DNA-binding transcription factor activity. It is associated with the regulation of systemic acquired resistance, salicylic acid-mediated signaling, defense responses to bacteria and insects, and responses to herbivores, calcium ions, and red or far-red light. The protein localizes to the plasma membrane, cytosol, endoplasmic reticulum, nuclear bodies, and stress granules. CaNIM1 is linked to traits including drought tolerance, herbivore resistance, disease resistance to various pathogens, and responses to abiotic stresses such as aluminum, nitrogen, and sulfur sensitivity. Related genes in other species connect it to pathogen resistance, systemic acquired acclimation to high light, and oxidative stress tolerance.
