YS1 — Sorghum bicolor

Summary

SORBI_3006G264700 (YS1) on sorghum chromosome 6 encodes a YSL-like protein with Fe-NA chelate transporter and oligopeptide transmembrane transporter activity. It is associated with iron ion membrane transport, response to iron and zinc, glutathione and sucrose metabolism, phenylpropanoid and lignin anabolism, seed development, defense response, and signal transduction. The protein localizes to plastid envelope, vacuolar membrane, tonoplast, Golgi, mitochondria, and plasma membrane. YS1 is associated with grain filling period, photosynthetic rate, chlorophyll content, heavy metal stress response and tolerance, 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. Related genes in other species are linked to iron transport, seed metal loading, metal remobilization during senescence, and tolerance to iron deficiency and saline-alkaline stress.
