PR2 — Capsicum annuum

Summary

CaPR2 (T459_13848) on pepper chromosome 5 encodes a glucan endo-1,3-beta-D-glucosidase, a member of the glycosyl hydrolase family 17, with O-glucosyl hydrolase and protein homodimerization activities. This vacuolar and extracellular protein is associated with 1,3-beta-glucan breakdown, carbohydrate metabolism, defense response, immune response, induced systemic resistance, hypersensitive response-programmed cell death, cell death, jasmonic acid signaling, virus-induced post-transcriptional gene silencing, leaf formation, and nitrogen fixation. It is linked to photosynthetic rate and plant height. Related genes in other species are associated with disease and virus resistance, and with traits including fruit weight, starch content, drought tolerance, chlorophyll content, and germination rate.
