PR5 — Solanum lycopersicum

Summary

SlPR5 (SOLYC08G080590.3) encodes a thaumatin-like protein belonging to the osmotin/thaumatin superfamily, with beta-glucanase and endo-1,3(4)-beta-glucanase activity. This tomato gene on chromosome 8 is associated with antifungal innate immune response, induced systemic resistance, and response to host. It is linked to regulation of proline anabolism, lycopene anabolism, salicylic acid anabolism, auxin anabolism, ethylene anabolism, chlorophyll anabolism, ergosterol anabolism, fermentation, photoperiodism, and metabolic burst. The protein localises to the vacuole, apoplast, extracellular space, and cytoplasm. SlPR5 is linked to fruit shape, sugar content, protein content, seed size, stomatal opening, and sensitivity to acid and abscisic acid. Related genes in other species connect the family to endo-1,3(4)-beta-glucanase activity.
