NAS1 — Oryza sativa Japonica

Summary

OS03G0307300, also known as NAS1, encodes a nicotianamine synthase with EC 2.5.1.43, placing it in the Nicotian_synth domain family. In rice, this gene is associated with saline-alkaline stress tolerance, vascular bundle and xylem development, ethylene response, and transcription factor activity. The gene is linked to grain zinc and iron content, root and shoot traits, zinc deficiency response, and endosperm development. Annotated associations include zinc and iron content traits, seedling height, panicle length, grain protein content, grain yield, heat tolerance, leaf chlorosis, and salt tolerance. The encoded product is associated with nicotianamine anabolism, phytoalexin biosynthesis, cell redox homeostasis, response to iron and zinc, seed maturation, phloem transport, and chlorophyll anabolism. Related genes in other species link the family to iron transport, homeostasis, and deficiency response, as well as cadmium detoxification and tolerance.
