Human heart health benefits from a diet rich in the polyunsaturated fatty acids found in oily fish such as salmon and anchovies. Unfortunately, marine fisheries are increasingly fragile, and farm-raised salmon require expensive supplements to generate the desirable fatty acids. Ruiz-Lopez et al. engineered the oilseed crop plant Camelina into a source of the key fatty acids by plucking enzymes from sources as diverse as phytoplankton, microalgae, and oomycetes. Camelina expressing the transgenes made as much as a quarter of their seed lipids into replacements for fish oil, surpassing salmon, pound for pound, as a source of the right fatty acids.

Widely grown Camelina sativa can be engineered to produce fish oil
