PR5 — Capsicum annuum

Summary

CaPR5 (T459_12127) on pepper chromosome 4 encodes a protein of the osmotin/thaumatin-like superfamily with mRNA and protein binding activities. The gene is associated with immune response, systemic acquired resistance, hypersensitivity, cell death, and defence against bacteria and viruses. It is linked to responses to salicylic acid, ethylene, UV-B, cadmium, and arachidonate, as well as regulation of anthocyanin metabolism and the metabolic burst. The protein localises to the apoplast, cell wall, vacuole, plasmodesmata, secretory vesicles, membrane, and mitochondria. CaPR5 has been connected to agronomic traits including plant height, stem diameter, leaf area index, and chlorophyll content, and to tolerance of drought, salt, and osmotic stress, as well as resistance to Verticillium dahliae and Pseudomonas syringae.
