YS1 — Sorghum bicolor

Summary

SORBI_3006G164200 (YS1) on sorghum chromosome 6 encodes a YSL-like protein with Fe-NA chelate transporter and oligopeptide transmembrane transporter activity, placing it in the OPT family. The gene is associated with iron transport and response to iron, as well as glutathione, sucrose, phenylpropanoid and lignin metabolism. It has been linked to seed development, defense response, signal transduction, and chlorophyll content. The product localizes to the vacuolar membrane, plasmalemma, and general membrane. Related genes in other species link the family to metal-chelate transport and iron homeostasis.
