Abstract
AbstractPlant fatty acids are used for food, feed, fuel, and industrial materials. Structurally and chemically diverse fatty acids, referred to as unusual or specialized fatty acids, are found in the seed oils of diverse plant species. Many unusual fatty acids have potential use as alternative and renewable sources of biofuels and bio‐based industrial feedstocks due to their variant structures' physical or functional properties. Oils enriched in these fatty acids can increase the value of oilseed crops and provide co‐products that can be readily extracted from lignocellulosic materials in biomass crops. Here, we describe recent progress in strategies for enhancement of oil production and quality in oilseed crops and the extension of this knowledge for metabolic engineering of biomass crops. Successful implementation of these strategies, in part, through the use of emerging synthetic biology tools, will provide added product value for the economic sustainability of biomass crops as bioenergy feedstocks.
Highlights
Vegetable oils extracted from plant seeds have been widely used for food, feed, and industrial materials
Bio-prospecting in the plant kingdom has led to the identification and biochemical characterization of specialized enzymes involved in the synthesis and metabolism of unusual fatty acids
Recent studies have to lead to new strategies to limit feedback inhibition of fatty acid and TAG biosynthesis caused by unusual fatty acid metabolism in engineered oilseed hosts
Summary
Vegetable oils extracted from plant seeds have been widely used for food, feed, and industrial materials. In the case of seeds from species such as those from the Cuphea genus that produce oils with ≥90% of saturated C8 and C10 fatty acids or castor bean that accumulates >90% of the Δ12-hydroxylated ricinoleic acid, structurally and functionally variant LPATs have been identified that enable accumulation of these unusual fatty acids at the TAG sn-2 position (H.J. Kim et al, 2015; Lunn, Wallis, & Browse, 2019).
