PR5 — Capsicum annuum

Summary

CaPR5 (T459_34253) on pepper chromosome PGAv.1.6.scaffold1577 encodes a member of the osmotin/thaumatin-like superfamily with glucan endo-1,3-beta-D-glucosidase activity, IgE binding, mRNA binding and protein binding. The gene is associated with diverse stress and defence responses including response to bacteria, viruses, UV-B, ethylene, salicylate, cadmium, arachidonate, and salinity, as well as hypersensitivity, systemic acquired resistance, innate immunity, cell death, metabolic burst, virus-induced PTGS, and regulation of anthocyanin anabolism. It localises to the apoplast, plant-type cell wall, vacuole, secretory vesicle, plasmodesma, membrane, mitochondria and extracellular space. Associations with agronomic traits include leaf area index, stem diameter, chlorophyll content, plant height, and linked phenotypes such as disease resistance, fungal resistance, salt tolerance, drought tolerance, osmotic stress response, proline accumulation, insect resistance, and resistance to Verticillium dahliae and Pseudomonas syringae. Related genes in other species link the family to seed germination under salt stress, cell wall integrity, and reduced ABA responses.
