YS1 — Sorghum bicolor

Summary

SORBI_3006G152801, designated YS1 (also known as SbYSL3–SbYSL9 and YSL1, YSL14, YSL17, YSL18), encodes a YSL-like protein of the OPT family with Fe-NA chelate transporter and oligopeptide transmembrane transporter activity. In sorghum, this gene is associated with iron ion membrane transport, responses to iron and zinc, glutathione and sucrose metabolism, phenylpropanoid and lignin anabolism, seed development, defense response, and signal transduction. It is linked to grain filling period, photosynthetic rate, chlorophyll content, heavy metal stress response, heavy metal stress tolerance, chromium stress response, iron tolerance, iron deficiency tolerance, iron homeostasis, seed iron content, copper distribution, mineral transport, copper remobilization, iron remobilization, zinc remobilization, metal ion homeostasis, and copper homeostasis. The protein localizes to the plastid envelope, vacuolar membrane, tonoplast, Golgi, mitochondria, and plasmalemma. Related genes in other species are linked to mineral and ion transport, grain size and weight, yield, root morphology, plant height, and disease tolerance.
