YS1 — Sorghum bicolor

Summary

SORBI_3004G299700, designated YS1 (also known as SbYSL3–SbYSL9, YSL1, YSL14, YSL17, YSL18), encodes a member of the YSL-like and OPT protein families on sorghum chromosome 4. The product possesses Fe-NA chelate transporter activity and oligopeptide transmembrane transporter activity, and is associated with iron transport, response to iron, glutathione metabolism, sucrose metabolism, cell wall modification, phenylpropanoid and lignin anabolism, seed development, defense response, and signal transduction. It localizes to the vacuolar membrane, plasmalemma, and membrane. The gene is linked to chlorophyll content. Studies of related genes in other species connect the family to metal chelate transport.
