PR1 — Zea mays

Summary

ZM00001EB341580, designated ZmPR1 on maize chromosome 8, encodes a CAP-domain protein of the V5 allergen-like family and exhibits cytokine activity. The gene is associated with activation of immune response, cytokine production, and salicylic acid metabolism, as well as responses to water, herbivore, and thiamin. It is linked to defense responses, systemic acquired resistance, disease resistance, and salt tolerance, along with traits including grain yield, plant height, anthocyanin content, total soluble sugar content, and germination rate. The encoded protein localizes to the secretory vesicle, vacuole, plant-type cell wall, and extracellular space. Studies of related genes in other species connect the family to salicylic acid-mediated defense, pathogen resistance, and abiotic stress tolerance.
