PR5 — Capsicum annuum

Summary

CaPR5 (T459_00348) on pepper chromosome 1 encodes a thaumatin-like protein belonging to the osmotin/thaumatin-like superfamily and exhibits beta-glucanase, endo-1,3(4)-beta-glucanase, glycosidase and hydrolase activities. The gene is associated with antifungal innate immune response, defence response to fungi, hypersensitivity, cell death, metabolic burst, response to virus and virus-induced PTGS, as well as responses to jasmonic acid and ethylene. It is linked to signal transduction, innate immunity, salinity response and killing of cells of other organisms. The protein localises to the vacuole, extracellular space and cytoplasm. CaPR5 is also linked to agronomic traits including leaf area index, stem diameter, chlorophyll content and plant height. Related genes in other species support the family’s association with endo-1,3(4)-beta-glucanase activity.
