YS1 — Oryza sativa Japonica

Summary

OsYS1 (OS05G0252000) on rice chromosome 5 encodes a member of the YSL (Yellow Stripe-Like) family, specifically YSL4, which belongs to the OPT (Oligopeptide Transporter) superfamily and possesses oligopeptide transmembrane transporter activity. The gene is associated with iron transport and response to iron, nitrogen fixation, phytoalexin biosynthesis, pH reduction, glutathione metabolism, secretion, phloem transport, detoxification, embryogenesis, seed maturation and germination, chlorophyll anabolism, and homeostasis. It is linked to membrane localisation. Traits associated with OsYS1 include grain yield, grain weight, harvest index, grain filling period, plant height, leaf temperature, leaf chlorosis, iron concentration, chlorophyll content, net photosynthetic rate, transpiration rate, stomatal resistance, and photosynthetic rate.
