YS1 — Oryza sativa Japonica
Summary
OsYS1 (OS04G0524600) encodes a YSL-like protein with Fe-NA chelate transporter and oligopeptide transmembrane transporter activity, placing it in the OPT family. In rice, the gene is associated with seed iron concentration, grain iron content, metal transport, and saline-alkaline stress tolerance. It is linked to iron ion membrane transport, phytoalexin biosynthesis, nitrogen fixation, response to iron and zinc, glutathione metabolism, phloem transport, and seed maturation. The protein localises to the plastid envelope, vacuolar membrane, tonoplast, Golgi, mitochondria, and plasma membrane. Associations with leaf temperature, grain filling period, chlorophyll content, photosynthetic rate, grain weight, plant height, and grain yield have been noted. Studies of related genes in other species link the family to seed metal loading, copper distribution, and metal remobilisation during senescence.
