PR5 — Solanum tuberosum

Summary

StPR5 (PGSC0003DMG400006202) on potato chromosome 1 encodes a thaumatin-like protein with glucan endo-1,3-beta-D-glucosidase activity, and is associated with IgE binding, mRNA binding, and protein binding. The gene is linked to late blight resistance in potato, as well as defence responses to bacteria, fungi, and viruses, systemic acquired resistance, and cell death. It has been connected to responses to abscisic acid, ethylene, UV-B, cadmium, and osmotic stress, and to the regulation of anthocyanin anabolism. The protein localises to the apoplast, plant-type cell wall, vacuole, plasmodesma, secretory vesicle, and membrane. Associations also include disease resistance to Pseudomonas syringae and Verticillium dahliae, insect resistance, salt and drought tolerance, and proline accumulation. Studies of related genes in other species link the family to pathogen resistance, induced systemic resistance, and seed germination under salt stress.
