PR5 — Cucumis sativus

Summary

CsPR5 (CSA_2G361370) on cucumber chromosome 2 encodes a pathogenesis-related protein 5-like thaumatin family member with glucan endo-1,3-beta-D-glucosidase activity and IgE binding. The gene is associated with systemic acquired resistance, defence response to fungi, and responses to salicylate, ethylene, abscisic acid, and arachidonate. It is linked to salinity response, killing of cells of other organisms, and localises to the apoplast and extracellular space. Studies of related genes in other species link the family to glucan endo-1,3-beta-glucosidase activity (EC 3.2.1.39).
