YS1 — Oryza sativa Japonica

Summary

OsYS1 (OS08G0280300) encodes a member of the YSL-like and OPT protein families, with annotated oligopeptide transmembrane transporter activity. In rice, this gene is associated with iron transport and response to iron, nitrogen fixation, phytoalexin biosynthesis, pH reduction, glutathione metabolism, secretion, phloem transport, detoxification, chlorophyll anabolism, homeostasis, seed maturation, embryogenesis, and seed germination. It localizes to the vacuolar membrane and membrane. OsYS1 is linked to several agronomically important traits, including grain yield, grain weight, harvest index, grain filling period, plant height, leaf temperature, leaf chlorosis, chlorophyll content, net photosynthetic rate, transpiration rate, stomatal resistance, and iron concentration. Studies of related genes in other species further connect this gene family to metal transport processes.
