PR5 — Solanum tuberosum

Summary

StPR5 (PGSC0003DMG400025250) on potato chromosome 1 encodes a thaumatin-like protein, a member of the osmotin/thaumatin-like superfamily, with glucan endo-1,3-beta-D-glucosidase activity and IgE binding capacity. The gene is associated with defense responses, including systemic acquired resistance, induced systemic resistance, and defense against fungi. It is also linked to cell death, cell division, DNA replication, nitric oxide storage, and response to abscisic acid and stress. The protein localizes to the apoplast and extracellular space. Related genes in other species connect the family to glucan endo-1,3-beta-glucosidase activity (EC 3.2.1.39).
