NAS1 — Oryza sativa Japonica
Summary
Os03g0307200, designated NAS1 (also known as NAS2, NAS3, or NAS4) in rice (Oryza sativa Japonica) on chromosome 3, encodes a nicotianamine synthase with EC 2.5.1.43, placing it in the nicotianamine synthase family and the SAM-dependent methyltransferase superfamily. The gene is associated with nicotianamine anabolism, phytoalexin biosynthesis, and responses to iron and zinc. It has been linked to saline-alkaline stress tolerance, grain zinc and iron content, and traits such as seedling height, plant height, panicle length, chlorophyll content, grain yield, and heat tolerance. Localization evidence connects it to the nucleus. Studies of related genes in other species link the family to iron transport, homeostasis, and cadmium detoxification.
