PR5 — Solanum lycopersicum

Summary

SlPR5 (SOLYC12G056390.1) encodes a thaumatin-like protein belonging to the osmotin/thaumatin-like superfamily, with beta-glucanase and endo-1,3(4)-beta-glucanase activities. This gene is associated with antifungal innate immune response, induced systemic resistance, and regulation of proline, lycopene, salicylic acid, auxin, ethylene, and chlorophyll anabolism. It is linked to the apoplast and vacuole, and has been connected to fruit shape, sugar content, protein content, seed size, stomatal opening, and sensitivity to acid and abscisic acid. Studies of related genes in other species link the family to endo-1,3(4)-beta-glucanase activity (EC 3.2.1.6).
