PR5 — Brassica oleracea

Summary

BoPR5, encoded by gene BOLC102_C06P054220.1 on cabbage chromosome 6, belongs to the thaumatin-like protein family and exhibits glucan endo-1,3-beta-D-glucosidase activity, IgE binding, and mRNA binding. The protein localises to the apoplast, cell wall, secretory vesicles, vacuole, and mitochondria. BoPR5 is associated with defence responses to fungi, viruses, and bacteria including Pseudomonas syringae and Verticillium dahliae, as well as responses to salicylate, ethylene, abscisic acid, UV-B, cadmium, and salinity. It is linked to cell death, secretion, lateral root and root development, regulation of anthocyanin anabolism, and egg deposition. Phenotype associations include systemic acquired resistance, insect resistance, drought tolerance, salt tolerance, and stress responses. Related genes in other species are linked to disease resistance, nematode resistance, herbivore defence, seed germination under salt stress, and cell wall integrity.
