PR5 — Solanum tuberosum

Summary

StPR5 (PGSC0003DMG400006543) on potato chromosome 11 encodes a thaumatin-like protein belonging to the osmotin/thaumatin-like superfamily. The gene is associated with a broad range of biological processes, including defence responses to fungi, induced systemic resistance, systemic acquired resistance, and cell death. It is also linked to responses to abscisic acid, ethylene, salicylate, UV-B, and salinity, as well as to pollen hydration and germination. The encoded product localises to the vacuole, endoplasmic reticulum, Golgi cisterna, vesicles, and pollen wall structures such as the intine, exine, tryphine, and orbicules. Related genes in other species encode thaumatin-like proteins, including pollen allergens and osmotin-like proteins.
