YS1 — Oryza sativa Japonica

Summary

OsYS1 (OS04G0674600) encodes a YSL-like protein belonging to the OPT family, with oligopeptide transmembrane transporter activity. It is associated with iron transport and response to iron, nitrogen fixation, phytoalexin biosynthesis, pH reduction, glutathione metabolism, secretion, phloem transport, detoxification, chlorophyll anabolism, homeostasis, embryogenesis, seed maturation, seed development, and seed germination. The protein localises to the vacuolar membrane, plasmalemma, and membrane. OsYS1 has been linked to several agronomically important traits, including grain yield, grain weight, harvest index, plant height, leaf temperature, leaf chlorosis, iron concentration, net photosynthetic rate, transpiration rate, stomatal resistance, and chlorophyll content. Studies of related genes in other species further connect the family to metal transport processes.
