Biofortification of safflower: an oil seed crop engineered for ALA-targeting better sustainability and plant based omega-3 fatty acids

Abstract

Alpha-linolenic acid (ALA) deficiency and a skewed n6:n3 fatty acid ratio in the diet is a major explanation for the prevalence of cardiovascular diseases and inflammatory/autoimmune diseases. There is mounting evidence of the health benefits associated with omega-3 long chain polyunsaturated fatty acids (LC PUFA's). Although present in abundance in fish, a number of factors limit our consumption of fish based omega-3 PUFA's. To name a few, overexploitation of wild fish stocks has reduced their sustainability due to increased demand of aquaculture for fish oil and meal; the pollution of marine food webs has raised concerns over the ingestion of toxic substances such as heavy metals and dioxins; vegetarians do not consider fish-based sources for supplemental nutrition. Thus alternative sources are being sought and one approach to the sustainable supply of LC-PUFAs is the metabolic engineering of transgenic plants with the capacity to synthesize n3 LC-PUFAs. The present investigation was carried out with the goal of developing transgenic safflower capable of producing pharmaceutically important alpha-linolenic acid (ALA, C18:3, n3). This crop was selected as the seeds accumulate ~ 78% of the total fatty acids as linoleic acid (LA...Continue Reading

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.
