PR5 — Solanum tuberosum

Summary

StPR5 (PGSC0003DMG400009871) on potato chromosome 4 encodes a thaumatin-like protein with glucan endo-1,3-beta-D-glucosidase activity and IgE binding capacity. The protein belongs to the osmotin/thaumatin-like superfamily and is localised to the apoplast and extracellular space. StPR5 is associated with defence responses, including systemic acquired resistance, induced systemic resistance, defence response to fungi, and cell death. It has also been connected to responses to abscisic acid, stress, DNA replication, cell division, nitric oxide storage, and killing of cells of other organisms. Related genes in other species link the family to glucan endo-1,3-beta-glucosidase activity.
