YS1 — Oryza sativa Japonica
Summary
YS1 (YSL2) on rice chromosome 2 encodes a member of the YSL/OPT family with Fe-NA chelate transporter and oligopeptide transmembrane transporter activity. The gene is associated with iron transport, nitrogen fixation, phytoalexin biosynthesis, glutathione metabolism, and responses to iron, zinc, and nematodes. It is linked to seed iron concentration and content, grain traits, metal transport, and saline-alkaline stress tolerance. The protein localises to multiple membranes including the plastid envelope, tonoplast, vacuolar membrane, Golgi, plasmalemma, mitochondria, and extracellular space. Associations also extend to grain filling period, harvest index, photosynthetic rate, chlorophyll content, plant height, grain weight and yield, leaf chlorosis, and stomatal resistance. Related genes in other species connect the family to seed metal loading, copper and zinc homeostasis, metal remobilisation during senescence, and pathogen susceptibility.
