PR5 — Solanum tuberosum

Summary

StPR5 (PGSC0003DMG400004262) on potato chromosome 12 encodes a thaumatin-like protein with beta-glucanase, endo-1,3(4)-beta-glucanase, glycosidase, hydrolase, mRNA binding, and protein binding activities. It is associated with late blight resistance in potato, as well as antifungal innate immune response, systemic acquired resistance, cell death, and responses to jasmonic acid, ethylene, UV-B, cadmium, viruses, bacteria, and fungi. The protein localizes to the apoplast, vacuole, secretory vesicle, plant-type cell wall, plasmodesma, membrane, and mitochondria. StPR5 is also linked to regulation of anthocyanin anabolism, DNA replication, and NO storage. Related genes in other species link the family to osmotic stress response, proline accumulation, abscisic acid response, disease resistance, salt tolerance, drought tolerance, and resistance to Verticillium dahliae and Pseudomonas syringae.
