PR-1 — Capsicum annuum

Summary

CaPR-1 (T459_22804) on pepper chromosome 9 encodes an SCP domain-containing protein belonging to the CRISP-related CAP family. The gene is associated with defense responses, including systemic acquired resistance, immune response, innate immunity, and defense against other organisms, as well as cell death, metabolic burst, signal transduction, and sexual reproduction. The product localizes to the extracellular region and vacuole. Associations with agronomically relevant traits include fruit length and weight, heterosis, seed viability, and drought tolerance. Studies of related genes in other species link the family to traits such as fruit firmness, fruit shape and size, plant height, chlorophyll content, seedling vigor, root length and volume, stem width, leaf number, and responses to abscisic acid and acid sensitivity.
