EF1A — Brachypodium distachyon

Summary

BdEF1A (BRADI_1G06851V3) on chromosome 1 of Brachypodium distachyon encodes a eukaryotic translation elongation factor 1-alpha, a GTP-binding protein with GTPase activity that also exhibits SUMO transferase activity, SUMO binding, and protein tag activity. 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 protein localises to multiple cellular compartments including the cytosol, chloroplast stroma, mitochondria, vacuole, nucleolus, Golgi complex, and plasmodesmata. Related genes in other species are linked to drought tolerance, water use efficiency, seed germination, and immune response.
