Red-billed quelea including annual grasses of the genera "Echinochloa", "Panicum", "Setaria", "Sorghum", "Tetrapogon" and "Urochloa". One survey at Lake Chad showed that two thirds of the seeds eaten belonged to only three species: African wild rice ("Oryza barthii"), "Sorghum purpureosericeum" and jungle rice ("Echinochloa colona"). When the supply of these seeds runs out, seeds of cereals such as barley ("Hordeum disticum"), teff ("Eragrostis tef"), sorghum ("Sorghum bicolor"), manna ("Setaria italica"), millet ("Panicum miliaceum"), rice ("Oryza sativa"), wheat ("Triticum"), oats ("Avena aestiva"), as well as buckwheat ("Phagopyrum esculentum") and sunflower ("Helianthus annuus") are eaten on a large scale. Red-billed queleas have also been
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".
