PR5 — Asparagus officinalis

Summary

A4U43_C05F23640, also known as PR5 or AoPR5, encodes a protein with a thaumatin-like domain and osmotin/thaumatin-like superfamily domain, and is annotated with glucan endo-1,3-beta-D-glucosidase activity. The gene is associated with defence responses, including systemic acquired resistance, response to viruses, bacteria, and fungi, as well as killing of cells of other organisms. It is linked to responses to abscisic acid, ethylene, UV-B, and cadmium, and to regulation of anthocyanin anabolism. The protein localises to the apoplast, plant-type cell wall, secretory vesicle, vacuole, and plasmodesmata. Associations include disease resistance, salt and drought tolerance, insect resistance, and resistance to Verticillium dahliae and Pseudomonas syringae. Studies of related genes in other species link the family to pathogen resistance, induced systemic resistance, and seed germination under salt stress.
