STAR1 — Sorghum bicolor

Summary

SORBI_3010G246200, designated STAR1 on sorghum chromosome 10, encodes an ABC transporter domain-containing protein with ATP hydrolase activity and ATP binding. The gene is associated with aluminium ion transmembrane transport and detoxification of aluminium ions, and has been connected to aluminium tolerance as a trait. Additional associations include UDP-glucose transmembrane transport, phosphate ion membrane transport, and response to aluminium stress. The encoded protein localises to the ATP-binding cassette (ABC) transporter complex, vesicle membrane, tonoplast, and mitochondria. Studies of related genes in other species link the family to aluminium tolerance.
