PR5 — Capsicum annuum

Summary

CaPR5 (T459_11528) on pepper chromosome 4 encodes a thaumatin-like protein 1 belonging to the osmotin/thaumatin-like superfamily and is annotated with glucan endo-1,3-beta-D-glucosidase activity, IgE binding, mRNA binding, and protein binding. The gene is associated with defence responses to bacteria, fungi, and viruses, systemic acquired resistance, innate immunity, hypersensitivity, cell death, metabolic burst, and virus-induced post-transcriptional gene silencing. It is linked to responses to abscisic acid, ethylene, UV-B, cadmium, and osmotic stress, as well as regulation of anthocyanin anabolism. The protein localises to the apoplast, plant-type cell wall, vacuole, plasmodesmata, secretory vesicles, membrane, and mitochondria. Associations with agronomic traits include plant height, stem diameter, leaf area index, and chlorophyll content.
