PR5 — Cucumis sativus

Summary

CsPR5 (CSA_3G004490) in cucumber (Cucumis sativus) on chromosome 3 encodes a thaumatin-like protein with glucan endo-1,3-beta-D-glucosidase activity and IgE binding capacity. This protein is localized to the apoplast and extracellular space. CsPR5 is associated with systemic acquired resistance, defense response to fungi, and general defense response, as well as response to abscisic acid. It is also linked to killing of cells of other organisms. Studies of related genes in other species connect the thaumatin-like protein family to similar defense-related functions, including glucanase activity.
