PR5 — Cucumis sativus

Summary

CsPR5 (CSA_6G506010) encodes a protein belonging to the osmotin/thaumatin-like superfamily, with glucan endo-1,3-beta-D-glucosidase activity, and is associated with mRNA, protein, and IgE binding. The gene is linked to defence responses against bacteria, fungi, and viruses, systemic acquired resistance, and regulation of anthocyanin biosynthesis. It has been connected to responses to abscisic acid, ethylene, UV-B, cadmium, and osmotic stress, as well as to disease resistance, insect resistance, salt and drought tolerance, and resistance to Verticillium dahliae and Pseudomonas syringae. The protein localises to the apoplast, plant-type cell wall, vacuole, plasmodesma, secretory vesicle, membrane, and mitochondria. Studies of related genes in other species link the family to pathogen resistance, induced systemic resistance, nematode resistance, and seed germination under salt stress.
