PR1 — Brachypodium distachyon

Summary

BRADI_1G64890V3 (BdJIOSPR10, also known as PR1) on chromosome 1 encodes a Bet_v_I/MLP domain-containing protein with abscisic acid binding, nuclease, hydrolase, signaling receptor, and protein phosphatase inhibitor activities. It is associated with immune and defense responses, ABA signaling, and localizes to both the cytoplasm and nucleus. The gene is linked to flower, root, and palea development, as well as responses to biotic and abiotic stresses including drought, salt, oxidative stress, and ethylene. Associations with defense, stress tolerance, and defense response have also been noted. Related genes in other species connect the family to jasmonic acid signaling, seedling development, blast disease resistance, and root development.
