YS1 — Sorghum bicolor

Summary

SORBI_3004G224000, designated YS1 (also known as YSL1, YSL14, YSL17, YSL18, and SbYSL3–SbYSL9), encodes a member of the YSL-like/OPT protein family on sorghum chromosome 4. The product is an uncharacterized protein with oligopeptide transmembrane transporter activity. This gene is associated with response to iron, glutathione metabolism, sucrose metabolism, phenylpropanoid and lignin anabolism, seed development, defense response, and signal transduction. It is linked to vacuolar membrane, membrane, and plasmalemma localization. Chlorophyll content has also been connected to this gene. Studies of related genes in other species, such as YSL5, YSL9, and YSL16, link the family to metal transport, but these associations are not yet established for sorghum YS1.
