YS1 — Sorghum bicolor

Summary

SORBI_3003G343300, designated YS1 (also known as SbYSL3–SbYSL9, YSL1, YSL14, YSL17, and YSL18) on sorghum chromosome 3, encodes an uncharacterized protein belonging to the YSL-like and OPT domain families and is annotated with oligopeptide transmembrane transporter activity. The gene is associated with membrane localisation and has been linked to glutathione metabolism, sucrose metabolism, phenylpropanoid anabolism, lignin anabolism, defense response, and signal transduction. It is also associated with chlorophyll content. Studies of related genes in other species link the family to metal-chelate transport, though this is not established for sorghum.
