DAO — Oryza sativa Indica Group

Summary

BGIOSGA001294 (DAO) on chromosome 1 of Indica rice encodes a protein with a FAD-dependent oxidoreductase domain and exhibits D-aspartate oxidase and D-amino-acid oxidase activities. The gene is associated with nitrogen utilization, the ascorbate-glutathione cycle, the shikimate pathway, auxin metabolism, and signal transduction, and its product localizes to the cytoplasm and the chloroplast. DAO is associated with photosynthetic rate and chlorophyll content. Studies of related genes in other species link the family to test weight, grain weight, net photosynthetic rate, transpiration rate, stomatal resistance, photochemical quenching, proline content, protein content, and salinity tolerance.
