AMT1 — Oryza sativa Japonica

Summary

OS03G0826500 (AMT1, also known as OASA1) encodes a protein with anthranilate synthase and aminodeoxychorismate synthase activity (EC 4.1.3.27) that belongs to the ADC synthase family. In rice, this gene is associated with nitrogen homeostasis, PABA biosynthesis, tetrahydrofolate anabolism, folate biosynthesis, tryptophan formation, regulation of auxin biosynthetic process, nitrate import, pH reduction, phosphate homeostasis, system development, adventitious root development, glutathione metabolism, auxin anabolism, auxin transport, root hair elongation, syngamy, and lateral root development. The protein localizes to the anthranilate synthase complex, chloroplast stroma, cytoplasm, and nucleus. Associations with agronomic traits include root fresh weight, nitrogen content, adventitious rootless, root volume, grain yield per plant, root hair length, root number, lignin content, nitrate uptake, grain number, root length, chlorophyll content, anthesis time, and plant height. Related genes in other species are linked to tryptophan biosynthesis, auxin biosynthesis, and root growth inhibition.
