PR5 — Capsicum annuum

Summary

CaPR5 (T459_13406) on pepper chromosome 4 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 activities. The gene is associated with immune response, systemic acquired resistance, hypersensitivity, cell death, innate immunity, defence responses to bacteria and fungi, and virus-induced post-transcriptional gene silencing. It is linked to responses to abscisic acid, ethylene, UV-B, cadmium and bacteria, as well as regulation of anthocyanin anabolism and the metabolic burst. The product localises to the apoplast, plant-type cell wall, plant-type vacuole, plasmodesmata, secretory vesicle, 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, drought tolerance, salt tolerance, osmotic stress response, proline accumulation, insect resistance and resistance to Verticillium dahliae and Pseudomonas syringae.
