YS1 — Brachypodium distachyon

Summary

BdYS1 (BRADI_3G50267V3) on chromosome 3 of Brachypodium distachyon encodes a YSL-like protein with Fe-NA chelate transporter activity and oligopeptide transmembrane transporter activity. It is associated with iron transport, response to iron, secretion, seed development, homeostasis, and flower development, and localises to the vacuolar membrane, plasmalemma, and general membrane. The gene is linked to auxin influx transport, polar auxin transport, root gravitropism, and responses to abiotic stimuli. Associations with seed size, grain size, and grain yield have been noted. Studies of related genes in other species connect the family to metal homeostasis and transport.
