MAT1 — Oryza sativa Indica Group

Summary

BGIOSGA001851 (MAT1) on chromosome 1 of Indica rice encodes a methionine adenosyltransferase (EC 2.5.1.6) with S-AdoMet synthetase domains, and is also annotated with tRNA-adenosine deaminase, SUMO transferase, kinase, and DNA-binding transcription factor activities. The gene is associated with SAM biosynthetic and one-carbon metabolism processes, ethylene anabolism, lignin anabolism, sumoylation, and responses to brassinosteroid, auxin, and ethylene. In rice, it has been linked to fertility, flowering time, heading date, seed germination, seed size, grain traits, leaf and flower development, senescence, dwarfism, and ethylene response. Additional associations include grain number and yield, plant height, root hair length, stomatal opening, cadmium concentration, phosphorus response, callus induction, and disease tolerance. The protein localizes to the cytosol, ER, plasmodesma, nucleolus, and filiform apparatus.
