JAZ1 — Brachypodium distachyon

Summary

BdJAZ1 (BRADI_4G31240V3) on chromosome 4 of Brachypodium distachyon encodes a TIFY/JAZ family protein with sequence-specific DNA-binding and transcription corepressor activity, and is associated with chromatin binding, histone deacetylase activity, and calcium ion binding. The gene is linked to regulation of defense responses to insects, jasmonic acid/ethylene-dependent systemic resistance, stomatal lineage progression, seed dormancy, and ascorbate biosynthesis. It has been connected to numerous agronomic traits including seed protein content, seedling vigor, shoot elongation under submergence, plant size, stem length, branch angle, leaf trichome density, iron content, phosphorus and nitrate responses, temperature stress tolerance, and fruit ripening. Studies of related genes in other species link the family to stamen development, flavonol accumulation, and responses to salt, drought, and nutrient deficiency.
