PR5 — Capsicum annuum

Summary

CaPR5 (T459_13405) on pepper chromosome 4 encodes a protein of the osmotin/thaumatin-like superfamily with glucan endo-1,3-beta-D-glucosidase activity, mRNA binding, IgE binding and protein binding. The gene is associated with immune response, systemic acquired resistance, hypersensitivity, cell death, metabolic burst, and defence responses to bacteria, fungi and viruses, as well as virus-induced PTGS. It is linked to responses to abscisic acid, ethylene, UV-B, cadmium and bacteria, and to regulation of anthocyanin anabolism. The product localises to the apoplast, plant-type cell wall, plant-type vacuole, secretory vesicle, plasmodesma, membrane and mitochondria. Associations with agronomic traits include plant height, stem diameter, leaf area index and chlorophyll content, and with phenotypes such as disease resistance, salt and drought tolerance, osmotic stress response, proline accumulation, and resistance to Verticillium dahliae and Pseudomonas syringae.
