EF1A — Brachypodium distachyon

Summary

BdEF1A (BRADI_4G12750V3) on chromosome 4 of Brachypodium distachyon encodes a protein with a Transl_elong_EF1A_euk/arc domain, a GTP-binding protein with GTPase activity, translation elongation factor activity, and SUMO transferase and binding activities. The gene is associated with translation elongation, sumoylation, and regulation of metabolism, as well as stomatal closure, response to abscisic acid, seedling development, and embryo development ending in seed dormancy. It has been linked to traits including plant stress response, stomatal opening, abscisic acid sensitivity, flowering time, plant growth and development, and root morphology. The encoded protein localises to multiple cellular compartments including the cytosol, chloroplast stroma, mitochondria, vacuole, nucleolus, and plasmodesmata. Studies of related genes in other species connect the family to drought tolerance, water use efficiency, seed germination, and immune response.
