YS1 — Oryza sativa Japonica

Summary

OS01G0829900, designated YS1 and also known as YSL18, encodes a member of the YSL-like family with Fe-NA chelate transporter activity and oligopeptide transmembrane transporter activity. In rice, the gene is associated with seed iron concentration and grain iron content, as well as metal transport and saline-alkaline stress tolerance. It has been linked to crown root development, lamina and sheath traits, and pollen function. The encoded product localizes to the plastid envelope, tonoplast, Golgi, mitochondria, and plasma membrane. The gene is associated with nitrogen fixation, phytoalexin biosynthesis, iron and zinc responses, glutathione metabolism, phloem transport, and nematode response. Associations with grain weight, yield, plant height, chlorophyll content, photosynthetic rate, and leaf temperature have also been observed. Studies of related genes in other species link the family to seed metal loading, copper and zinc remobilization, and fertility.
