PR5 — Capsicum annuum

Summary

CaPR5 (T459_06215) on pepper chromosome 2 encodes a glucan endo-1,3-beta-glucosidase, a thaumatin-like protein belonging to the osmotin/thaumatin-like superfamily. The gene is associated with immune response, hypersensitivity, cell death, metabolic burst, and defence response to fungi, as well as with virus-induced PTGS, innate immunity, and response to abscisic acid. It is linked to IgE binding and killing of cells of other organisms. The product localises to the apoplast and extracellular space. CaPR5 has been connected to agronomic traits including leaf area index, stem diameter, chlorophyll content, and plant height. Studies of related genes in other species link the family to glucan endo-1,3-beta-glucosidase activity (EC 3.2.1.39).
