EF1A — Brachypodium distachyon

Summary

BdEF1A (BRADI_1G06861V3) on chromosome 1 of Brachypodium distachyon encodes a eukaryotic translation elongation factor 1-alpha, a GTP-binding protein with translation elongation factor activity, GTPase activity, and SUMO transferase activity. The gene is associated with translation elongation, sumoylation, and regulation of metabolism. It is linked to stomatal closure, response to abscisic acid, seedling development, and embryo development ending in seed dormancy. The protein localises to multiple cellular compartments including the cytosol, chloroplast stroma, mitochondria, vacuole, nucleolus, and plasmodesmata. Associations with plant stress response, stomatal opening, abscisic acid sensitivity, flowering time, root morphology, and plant growth and development traits have been reported. Studies of related genes in other species connect the family to drought tolerance, water use efficiency, seed germination, and immune response.
