PR2 — Capsicum annuum

Summary

CaPR2 (T459_13849) on pepper chromosome 5 encodes an X8 domain-containing protein with glucan endo-1,3-beta-D-glucosidase and O-glucosyl hydrolase activities, placing it in the Glyco_hydro_17 family. It 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. The protein localizes to the vacuole, extracellular space, and plasmalemma. CaPR2 is linked to photosynthetic rate and plant height. Studies of related genes in tomato associate the family with disease resistance and virus resistance.
