Plain language summary

Two bioactive omega-3 long-chain fatty acids (EPA and DHA), normally found in algal and fish oils, can now be produced in genetically engineered terrestrial oilseed crops. The production of these fatty acids by seed oil crops represents a fundamental shift in the accessibly of bioactive fatty acids to terrestrial consumers. Here we discuss the potential ecological and evolutionary consequences of the novel production of EPA and DHA by genetically engineered oilseed crops and suggest research directions.

Abstract

Two bioactive omega-3 long-chain fatty acids (EPA and DHA), found in algal and fish oils, can now be produced in genetically engineered terrestrial oilseed crops. These fatty acids are involved in key physiological functions in invertebrates and vertebrates. They are known to be synthesized by primary producers in aquatic ecosystems, but not by terrestrial crop plants. The production of these fatty acids by seed oil crops thus represents a fundamental shift in the accessibility of bioactive fatty acids to terrestrial consumers; one that may change their physiology and survival thereby altering ecological interactions amongst terrestrial organisms. Here we discuss the potential ecological and evolutionary consequences of the novel production of EPA and DHA by genetically engineered oilseed crops.
