PR5 — Capsicum annuum

Summary

CaPR5 (T459_00349) on pepper chromosome 1 encodes an osmotin-like protein OSML13, a member of the thaumatin superfamily with beta-glucanase and endo-1,3(4)-beta-glucanase hydrolase activity. This gene is associated with antifungal innate immune responses, defence against fungi and viruses, hypersensitivity, cell death, metabolic burst, and responses to jasmonic acid and ethylene. It is linked to salinity response, signal transduction, and virus-induced post-transcriptional gene silencing. The protein localises to the vacuole, apoplast, 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 further connect the family to endo-1,3(4)-beta-glucanase activity.
