PR5 — Solanum lycopersicum

Summary

SlPR5 (SOLYC07G017970.3) encodes a thaumatin-like protein belonging to the osmotin/thaumatin-like superfamily, with glucan endo-1,3-beta-D-glucosidase activity and IgE binding capacity. This tomato gene on chromosome 7 is associated with diverse biological processes including regulation of proline anabolism, lycopene anabolism, salicylic acid anabolism, auxin anabolism, chlorophyll anabolism, ethylene anabolism, ergosterol anabolism, fermentation, photoperiodism, induced systemic resistance, response to arachidonate, response to host, spore germination, mRNA breakdown, RNA metabolism, metabolic burst, and killing of cells of other organisms. It localizes to the apoplast and extracellular space. SlPR5 is associated with fruit shape, sugar content, protein content, seed size, stomatal opening, acid sensitivity, abscisic acid sensitivity, and salt tolerance. Related genes in other species link the family to glucan endo-1,3-beta-glucosidase activity (EC 3.2.1.39).
