PR5 — Capsicum annuum

Summary

CaPR5 (T459_06217) on pepper chromosome 2 encodes a thaumatin-like protein 1, belonging to the osmotin/thaumatin-like superfamily and possessing glucan endo-1,3-beta-D-glucosidase activity and IgE binding. This gene is associated with defence responses, including innate immunity, defence response to fungi, hypersensitivity, cell death, metabolic burst, and virus-induced PTGS. It is also linked to signal transduction, response to abscisic acid, and killing of cells of other organisms. CaPR5 localises to the apoplast and extracellular space. Additionally, it has been connected to agronomic traits such as plant height, stem diameter, leaf area index, and chlorophyll content. Studies of related genes in other species link the family to glucan endo-1,3-beta-glucosidase activity.
