GT1 — Brachypodium distachyon

Summary

BdGT1 (BRADI_1G49620V3) on chromosome 1 of Brachypodium distachyon encodes an oligopeptide transporter belonging to the OPT family, with oligopeptide transmembrane transporter activity. The gene is associated with oligopeptide transport, protein transport, and pollen sperm cell differentiation, and its product localises to the membrane, plasmalemma, and cytoplasm. BdGT1 is associated with cadmium tolerance, flowering time, glutathione transport, phytochelatin content in sink organs, cadmium distribution, and glutathione content in shoots. Studies of related genes in other species connect the family to cadmium accumulation in reproductive sink organs, peptide transport, stress resistance, metal homeostasis, and zinc transport into shoots. Sequence similarity with related genes in other species further links the family to traits including grain number, tiller number, plant height, spikelet number, drought tolerance, cold tolerance, and dry matter digestibility.
