MOT1 — Brachypodium distachyon

Summary

BRADI_2G08130V3 (MOT1, also known as BdMOT1 or BdSULTR5) on chromosome 2 of Brachypodium distachyon encodes a member of the MOT1/MOT2 protein family with molybdate and sulphate transporter activity. The gene is associated with molybdate ion export from the vacuole and molybdate ion transport, and its product localises to the vacuolar membrane, plant-type vacuole, mitochondria and general membrane. Associations with heading time and anthesis time have been noted, along with links to sodium accumulation, molybdenum homeostasis, lower root and shoot molybdenum content, and growth. Studies of related genes in other species connect the family to shoot molybdenum content, spikelet number, shoot fresh weight, root mass density, salinity tolerance, drought tolerance, and grain and development phenotypes.
