Oryza sativa indicates that rice domestication likely began before 5000 BC, but that most sites in China from which rice remains have been recovered are younger than 5000 BC. Rice begins to be cultivated in South Asia from as early as 5000 BC. Wild rice appeared in the Belan and Ganges valley regions of northern India as early as 4530 BC and 5440 BC, respectively, J.Bates et al.(2016) found early domestication process of rice in ancient South Asia was based around the wild species "Oryza nivara". This led to the local development of a mix of 'wetland' and 'dryland' agriculture of local
Arogenate dehydratase hybrida", "Sorghum bicolor"", "and "Oryza sativa"", "which are all considered higher-order plants. "Erwinia herbicola"" and Pseudomonas aeruginosa"" "are known to" "have homologues for cyclohexadienyl dehydratase. Of the plants with ADT homologues, both "Arabidopsis thaliana "and "Petunia hybrida "are known to have paralogues for the gene (six and three, respectively). Arogenate dehydratase Arogenate dehydratase (ADT) (EC 4.2.1.91) is an enzyme that catalyzes the chemical reaction Hence, this enzyme has one substrate, L-arogenate, but 3 products:L-phenylalanine, HO, and CO. Certain forms of the protein have the potential to catalyze a second reaction, L-prephenate → L-phenylpyruvate + HO + CO This enzyme participates
