Oryza glaberrima Oryza glaberrima Oryza glaberrima, commonly known as African rice, is one of the two domesticated rice species. It was first domesticated and grown in West Africa, and was brought to the Americas by enslaved West African rice farmers. It is now largely a subsistence crop, rarely sold in markets even in West Africa. While it has been partly replaced by higher-yielding Asian rice, and the number of varieties grown is declining, it persists, making up an estimated 20% of rice grown in West Africa. By comparison to Asian rice, it is hardy, pest-resistant, low-labour, suited to a variety of African
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
