PR5 — Solanum lycopersicum

Summary

SlPR5 (SOLYC02G083790.4) encodes a thaumatin-like protein with glucan endo-1,3-beta-D-glucosidase activity, belonging to the osmotin/thaumatin-like superfamily. It is associated with regulation of proline anabolism, anthocyanin anabolism, lycopene anabolism, chlorophyll anabolism, auxin anabolism, ethylene anabolism, and salicylic acid anabolism, as well as response to cadmium, photoperiodism, and fermentation. The protein localizes to the apoplast, plant-type cell wall, plant-type vacuole, plasmodesma, and secretory vesicle. SlPR5 is associated with fruit shape, sugar content, seed size, stomatal opening, and acid sensitivity, along with osmotic stress response, proline accumulation, disease resistance, pathogen response, defense response, fungal resistance, ABA response, stress response, salicylic acid defense response, insect resistance, salt tolerance, drought tolerance, UV-B stress response, resistance to Verticillium dahliae, and resistance to Pseudomonas syringae. Studies of related genes in other species connect the family to pathogen resistance, herbivore defense, and cell wall integrity.
