YS1 — Sorghum bicolor

Summary

SORBI_3006G164300, also known as YS1 or YSL1, encodes a member of the YSL-like family of oligopeptide transporters (OPT) with Fe-NA chelate transporter activity and oligopeptide transmembrane transporter activity. In sorghum, this gene is associated with saline-alkaline stress tolerance, iron transport and response to iron, glutathione metabolism, sucrose metabolism, phenylpropanoid and lignin anabolism, seed development, defense response, and signal transduction. The encoded protein localizes to the vacuolar membrane, plasmalemma, and general membrane. It is linked to chlorophyll content and salt tolerance (SALTTL). Studies of related genes in other species connect the family to iron uptake and transport in the root vascular system and response to iron deficiency.
