YS1 — Sorghum bicolor

Summary

SORBI_3006G053200, designated YS1, encodes a metal-nicotianamine transporter YSL6 family protein with Fe-NA chelate transporter activity and oligopeptide transmembrane transporter activity. This sorghum gene on chromosome 6 is associated with iron transport and response to iron, as well as glutathione metabolism, sucrose metabolism, phenylpropanoid and lignin anabolism. It has been linked to seed development, defense response, and signal transduction. The product localizes to the vacuolar membrane, plasmalemma, and general membrane. Additionally, YS1 is associated with chlorophyll content. Studies of related YSL family members in other species connect this gene family to metal homeostasis and transport processes.
