Scientists engineer yellow-seeded camelina with high oil output

Efforts to achieve net-zero carbon emissions from transportation fuels are increasing demand for oil produced by nonfood crops. These plants use sunlight to power the conversion of atmospheric carbon dioxide into oil, which accumulates in seeds. Crop breeders, interested in selecting plants that produce a lot of oil, look for yellow seeds. In oilseed crops like canola, yellow-seeded varieties generally produce more oil than their brown-seeded counterparts. The reason: The protein responsible for brown seed color—which yellow-seeded plants lack—also plays a key role in oil production.
