Oryza rufipogon Oryza rufipogon Oryza rufipogon, known as brownbeard rice, wild rice, and red rice, is a member of the genus "Oryza". It is native to East, South and Southeast Asia. It has a close evolutionary relation to "Oryza sativa", the plant grown as a major rice food crop throughout the world. "Oryza rufipogon" is an invasive species and listed as a 'noxious weed' by the United States, and also listed as a noxious weed in Alabama, California, Florida, Massachusetts, Minnesota, North Carolina, Oregon, South Carolina, and Vermont. According to the North American Plant Protection Association, "O. rufipogon" blends in with cultivated
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".
