Oryza glaberrima is a crossbreed of Carolina Gold and two "Oryza sativa" breeding lines called IR64 (Indica) and IR65610-24-3-6-3-2-3, which raised the yield, shortened the stem, and added an aromatic quality to the rice. 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
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".
