PR1 — Capsicum annuum

Summary

T459_31879 (PR1, CaPR1) in pepper (Capsicum annuum) on chromosome PGAv.1.6.scaffold504 encodes a protein belonging to the CAP superfamily (CAP_dom, Allrgn_V5/Tpx1_CS, CRISP-related). This gene is associated with a wide range of biological processes, including systemic acquired resistance, induced systemic resistance, immune response, defense response to other organisms, cell death, and killing of cells of other organisms. It is also linked to nitrogen fixation, carotenoid metabolism, phenylpropanoid metabolism, hormone-mediated signalling, detoxification, and homeostasis. The encoded protein localizes to the extracellular region and vacuole. Associations with agronomically important traits include fruit length, fruit weight, plant height, chlorophyll content, seed viability, heterosis, drought tolerance, disease tolerance, chilling injury resistance, and abiotic stress tolerance. Studies of related genes in other species link the family to disease resistance.
