YS1 — Sorghum bicolor

Summary

SORBI_3004G011800 (YS1, SbYS1) on sorghum chromosome 4 encodes a metal-nicotianamine transporter YSL7, a member of the YSL-like and OPT domain families, with oligopeptide transmembrane transporter activity. It is associated with glutathione metabolism, sucrose metabolism, phenylpropanoid anabolism, lignin anabolism, defense response, and signal transduction, and localizes to the vacuolar membrane and membrane. The gene is associated with chlorophyll content. Studies of related genes in other species link the family to metal transport, but these associations are not established for this sorghum gene.
