AMT1 — Oryza sativa Japonica

Summary

OS03G0264400 (AMT1, also known as OASA2) encodes an anthranilate synthase alpha subunit, an enzyme with anthranilate synthase and aminodeoxychorismate synthase activities. In rice, this gene is associated with tryptophan content and has been linked to nitrogen homeostasis, nitrate import, auxin biosynthesis and transport, root system development including adventitious root and root hair elongation, and phosphate homeostasis. It is also associated with grain yield, grain number, plant height, anthesis time, chlorophyll content, lignin content, and root traits such as fresh weight, length, volume, and number. The protein localises to the chloroplast stroma, cytoplasm, and nucleus. Studies of related genes in other species link the family to defense response and phytoalexin biosynthesis.
