MAT1 — Oryza sativa Indica Group

Summary

BGIOSGA001769 (MAT1) in Indica rice encodes a methionine adenosyltransferase (EC 2.5.1.6) that catalyzes S-adenosylmethionine (SAM) biosynthesis. The gene is associated with SAM biosynthetic and methionine metabolism processes, ethylene biosynthesis and signaling, lignin anabolism, and one-carbon metabolism. In this species, MAT1 has been linked to fertility, flowering time, heading date, seed germination, seed size, grain traits, leaf and flower development, senescence, dwarfism, and ethylene response. It is also associated with phosphorus and nutrient responses, cadmium concentration, root hair length, callus induction, brassinosteroid and auxin sensitivity, abiotic stress tolerance, grain number and yield, plant height, and salt tolerance. The encoded protein localizes to the cytosol, cytoplasm, endoplasmic reticulum, plasmodesmata, and nucleolus. Studies of related genes in other species link the family to vascular tissue development, iron deficiency response, DNA methylation, and stress responses.
