YS1 — Oryza sativa Japonica

Summary

Rice YSL16 (Os04g0542800) encodes a YSL-like oligopeptide transporter with Fe-NA chelate transporter activity, belonging to the OPT family. It is associated with iron transport and response to iron, as well as nitrogen fixation, phytoalexin biosynthesis, glutathione metabolism, phloem transport, secretion, detoxification, pollen germination, embryogenesis, seed maturation and development, seed germination, chlorophyll anabolism, and pH reduction. The protein localizes to the vacuolar membrane, plasmalemma, and general membrane. Phenotypically, YSL16 has been connected to leaf, root, shoot, vascular bundle, spikelet, palea, lemma, floral organ, seed, and homeostasis traits. Agronomically, it is linked to grain yield, grain weight, harvest index, grain filling period, plant height, chlorophyll content, net photosynthetic rate, transpiration rate, stomatal resistance, leaf temperature, leaf chlorosis, and iron concentration.
