PR2 — Capsicum annuum

Summary

CaPR2 (T459_28102) on pepper chromosome 11 encodes a protein with glucan endo-1,3-beta-D-glucosidase and lichenase activity, belonging to the glycosyl hydrolase 17 family. This gene is associated with defense responses, including induced systemic resistance, immune response, hypersensitive response-programmed cell death, and cell death, as well as jasmonic acid signaling and virus-induced post-transcriptional gene silencing. It is also linked to nitrogen fixation, leaf formation, and carbohydrate metabolism. The encoded protein localizes to the vacuole and extracellular space. CaPR2 has been connected to photosynthetic rate and plant height. Related genes in other species are associated with disease and virus resistance, and sequence similarity links the family to traits including drought tolerance, chlorophyll content, fruit weight, and germination rate.
