Oryza barthii grows in deep water, seasonally flooded land, stagnant water, and slowly flowing water or pools; it prefers clay or black cotton soils, and is found in open habitats. It is the progenitor of cultivated "Oryza glaberrima", African rice. Recently, the genome of "O. barthii" was sequenced. Oryza barthii Oryza barthii, also called Barth's rice, wild rice, or African wild rice, is a grass in the rice genus "Oryza". It is an annual, erect to semierect grass. It has leaves with a short ligule (<13 mm), and panicles that are compact to open, rarely having secondary branching. The inflorescence structure are
12-oxophytodienoate reductase 12-oxophytodienoate reductase 12-oxophytodienoate reductase (OPRs) is an enzyme of the family of Old Yellow Enzymes (OYE). OPRs are grouped into two groups: OPRI and OPRII – the second group is the focus of this article, as the function of the first group is unknown, but is the subject of current research. The OPR enzyme utilizes the cofactor flavin mononucleotide (FMN) and catalyzes the following reaction in the jasmonic acid synthesis pathway: This reaction occurs in peroxisomes in plants. Several isozymes have been discovered, with varying substrate stereospecificity: three in "Lycopersicon esculentum", 13 in "Oryza sativa", and five in "Arabidopsis thaliana".
