PR1 — Solanum tuberosum

Summary

PGSC0003DMG400043736, designated PR1 (also known as PR1B1 or StPR1) on potato chromosome 1, encodes a PR1 protein belonging to the CAP superfamily, which includes the V5 allergen-like and CRISP-related domains. The gene is associated with blackleg disease resistance and pathogen defense response, as well as broader defense responses to other organisms and fungi. Annotated biological processes include cell death, pH reduction, response to hormone, primary metabolism, killing of cells of other organisms, and NO storage. The product localizes to the extracellular region and vacuole. Related genes in other species link the family to disease tolerance and pathogen resistance.
