PR-1 — Solanum lycopersicum

Summary

SOLYC07G006700.1, designated SlPR-1, encodes a protein belonging to the CAP (cysteine-rich secretory proteins, antigen 5, and pathogenesis-related 1) superfamily, containing a V5 allergen-like domain and a CRISP-related region. In tomato, this gene is associated with pathogen and herbivore resistance. It has been linked to a wide range of biological processes, including viral life cycle, immune evasion, response to water, hormone metabolism, fatty acid breakdown, and sterol anabolism. The encoded protein is localized to the extracellular region and the vacuole. Associations with agronomically relevant traits include seedling vigor, fruit firmness, fruit size and shape, plant height, chlorophyll content, drought tolerance, and abscisic acid sensitivity. Studies of related genes in other species link the family to late blight resistance in potato and defense responses in cucumber.
