Sora (bird) Soras often eat the seeds of plants, such as smartweeds, bulrushes, sedges, and barnyard grasses. Seeds of annual wildrice ("Zizania aquatica") and rice cutgrass are eaten by soras in the eastern United States. A literature review lists crowngrass ("Paspalum" spp.) and rice ("Oryza sativa") as relatively important food sources for soras in the Southeast. Plants comprising <5% of the sora's diet are also listed and include spikerushes ("Eleocharis" spp.), duckweeds (Lemnaceae), pondweeds ("Potamogeton" spp.), panicgrasses ("Panicum" spp.), cordgrasses ("Spartina" spp.), and saltgrass ("Distichlis spicata"). Soras eat more plant food in fall and winter (68%–69%) than in spring and summer (40%).
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".
