AMT1 — Oryza sativa Japonica

Summary

OsAMT1 (OS06G0699700) encodes a protein with anthranilate synthase, aminodeoxychorismate synthase, and isochorismate mutase activities, and belongs to the anthranilate synthase family. It is associated with tryptophan, auxin, folate, phylloquinone, and glutathione biosynthesis, as well as nitrogen and phosphate homeostasis, nitrate import, pH reduction, and root system development including adventitious root and root hair elongation. The gene is linked to grain yield, grain number, plant height, anthesis time, chlorophyll content, root fresh weight, root volume, root length, root number, root hair length, lignin content, and nitrogen content. Studies of related genes in other species connect the family to tryptophan and auxin biosynthesis, lateral and adventitious root formation, root growth inhibition, and ethylene-insensitive root phenotypes.
