YS1 — Oryza sativa Japonica

Summary

OsYS1 (OS05G0251900) on rice chromosome 5 encodes a member of the YSL-like family of oligopeptide transporters, possessing oligopeptide transmembrane transporter activity. The gene is associated with iron transport and response to iron, as well as nitrogen fixation, phytoalexin biosynthesis, glutathione metabolism, and chlorophyll anabolism. It has been linked to phloem transport, secretion, detoxification, pH reduction, seed maturation, seed germination, and embryogenesis. Localised to the membrane, OsYS1 is associated with 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.
