PR5 — Solanum lycopersicum

Summary

SlPR5 (SOLYC06G073000.4) encodes a thaumatin-like protein belonging to the osmotin/thaumatin-like superfamily, with beta-glucanase and glucan endo-1,3-beta-D-glucosidase activity, and is associated with IgE binding. This gene is linked to antifungal innate immune response, induced systemic resistance, and the regulation of proline, salicylic acid, ethylene, auxin, lycopene, and chlorophyll anabolism. It is also associated with ergosterol anabolism, spore germination, fermentation, photoperiodism, and mRNA breakdown. The protein localizes to the vacuole, apoplast, and extracellular space. Associations with agronomic traits include fruit shape, sugar content, protein content, seed size, stomatal opening, and sensitivity to acid and abscisic acid. Related genes in other species link the family to glucan endo-1,3-beta-glucosidase activity (EC 3.2.1.39).
