PR-1 — Solanum tuberosum

Summary

PGSC0003DMG401029578, designated StPR-1 on potato chromosome 8, encodes a protein belonging to the CAP superfamily, containing a V5 allergen-like domain and a CRISP-related domain. The gene is associated with defense responses, including late blight resistance, pathogen defense, and systemic acquired resistance, as well as induced systemic resistance and cell death. It is linked to salicylic acid anabolism, secretion, pistil development, and sexual reproduction. The protein localizes to the extracellular region and vacuole. StPR-1 is also associated with root volume and length, nematode resistance, and osmotic stress response. Studies of related genes in other species link the CAP family to pathogen and herbivore resistance, and to traits including chlorophyll content, plant height, fruit firmness, and drought tolerance.
