Abstract:
Recent advances in gene isolation, plant transformation, and genetic engineering are being used extensively to alter metabolic pathways in plants by tailormade modifications to single or multiple genes. Many of these modifications are directed toward increasing the nutritional value of plant-derived foods and feeds. These approaches are based on rapidly growing basic knowledge, understanding, and predictions of metabolic fluxes and networks. Some of the predictions appear to be accurate, while others are not, reflecting the fact that plant metabolism is more complex than we presently understand. Tailor-made modifications of plant metabolism has so far been directed into improving the levels of primary metabolites that are essential for growth and development of humans and their livestock. Yet, the list of improved metabolites is expected to grow tremendously after new discoveries in nutritional, medical, and health sciences. Despite our extensive knowledge of metabolic networks, many of the genes encoding enzymes, particularly those involved in secondary metabolism, are still unknown. These genes are being discovered at an accelerated rate by recent advances in genetic and genomics approaches. In the present review, we discuss examples in which the nutritional and health values of plant-derived foods and feeds were improved by metabolic engineering. These include modifications of the levels of several essential amino acids, lipids, fatty acids, minerals, nutraceuticals, antinutritional compounds, and aromas.

Genetic, molecular, and genomic approaches to improve the value of plant foods and feeds
Recent advances in gene isolation, plant transformation, and genetic engineering are being used extensively to alter metabolic pathways in plants by tailormade modifications to single or multiple genes.
