PR5 — Nicotiana attenuata

Summary

A4A49_13365 (PR5, also known as PRR1) in Nicotiana attenuata encodes a thaumatin-like protein with beta-glucanase and endo-1,3(4)-beta-glucanase activity, placing it in the osmotin/thaumatin-like superfamily. This gene is associated with antifungal innate immune response, defence response to fungi, systemic acquired resistance, response to viruses, and programmed cell death. It is linked to ethylene anabolism, response to jasmonic acid, and posttranscriptional regulation of gene expression. The product localises to the vacuole and apoplast. PR5 has been connected to leaf curling. Related genes in other species link the family to glucan endo-1,3-beta-glucosidase activity (EC 3.2.1.6).
