PR5 — Cucumis sativus

Summary

CsPR5 (CSA_3G002750) in cucumber encodes a thaumatin-like protein 1, a member of the osmotin/thaumatin-like superfamily with glucan endo-1,3-beta-D-glucosidase activity and IgE binding capacity. This gene is associated with defence responses, including systemic acquired resistance, defence response to fungi, and killing of cells of other organisms. It is associated with responses to salicylate, ethylene, abscisic acid, and arachidonate, as well as salinity response. CsPR5 is linked to shoot and root development, and its product localises to the apoplast and extracellular space. Related genes in other species further connect the family to glucan endo-1,3-beta-glucosidase activity (EC 3.2.1.39).
