PR-1 — Solanum tuberosum

Summary

PGSC0003DMG400027491, symbol PR-1, on potato chromosome 7, encodes a CAP-domain protein of the V5 allergen-like family. The gene is associated with defense responses, including late blight resistance and resistance to Phytophthora infestans, as well as pathogen defense, disease resistance, and nematode resistance. It is linked to systemic acquired resistance, induced systemic resistance, cell death, secretion, and salicylic acid anabolism. Associations also include sexual reproduction, pistil development, and primary metabolism. The protein localises to the extracellular region and vacuole. Additionally, PR-1 is associated with root volume and root length. Studies of related genes in tomato link the family to pathogen and herbivore resistance, while sequence similarity analyses connect the family to traits such as drought tolerance, chlorophyll content, plant height, fruit firmness, and seedling vigor.
