Patna rice is known for its elongated kernel with grain length greater than 6 mm, and has been used as staple food by the local people for thousands of years. Sometimes, Patna rice is also called "Parimal" rice locally. This mildly flavoured rice comes from the Bihar region of the Ganges plains. It has a robust, long and narrow, opaque grain that keeps its
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".
