YS1 — Sorghum bicolor

Summary

SORBI_3006G152900, designated YS1 (also known as SbYSL3 through SbYSL9 and YSL1, YSL14, YSL17, YSL18), encodes an uncharacterized protein belonging to the YSL-like and OPT domain families on sorghum chromosome 6. The gene product is annotated with oligopeptide transmembrane transporter activity and is associated with response to iron, glutathione metabolism, sucrose metabolism, phenylpropanoid and lignin anabolism, seed development, defense response, and signal transduction. It localizes to the vacuolar membrane, plasmalemma, and general membrane. The gene is also linked to chlorophyll content. Studies of related YSL family members in other species, such as YSL5, YSL9, and YSL16, connect this family to metal transport processes, though these associations are not yet established for sorghum.
