  5. 4. Genetically modified tobacco (Nicotiana tabacum) plants for an increased production of wax esters

    University essay from SLU/Dept. Of Plant Biology

    Author : Linn Nilsson; [2022]
    Keywords : Wax esters; metabolic engineering; nicotiana tabacum; fatty acid reductase; phytyl ester synthase;

    Abstract : Wax esters (WE) are naturally occurring lipids consisting of a fatty acid bound to a fatty alcohol with an ester bond. As an alternative to petrochemicals, plant-derived WE:s are of considerable commercial interest as lubricants, but have in recent years also received great attention for their potential as a starting material for bio-fuel production.
