  • Publication number: 20230332096
    Abstract: The present invention relates to pheromone production, desaturated fatty alcohols or aldehydes or acetates using recombinant yeasts expressing acyl-CoA oxidase to shorten fatty acyl-CoA by two carbons, deleting endogenous acyl-CoA oxidase, express desaturase to introduce at least one double bond, acyl-CoA-reductase to convert fatty acyl-CoA into fatty alcohol. Further, acetyltransferase can be used to convert to desaturated acyl fatty acetate, alcohol dehydrogenase or fatty acyl oxidase to convert to desaturated fatty aldehyde.

  • Publication number: 20230242945
    Abstract: The present invention relates to methods of producing Amyelois transitella pheromone precursors and genetically modified plants and microorganisms capable of producing Amyelois transitella pheromone precursors. The genetically modified plants and microorganisms include a heterologous gene encoding a first fatty-acyl desaturase and a second fatty-acyl desaturase in combination, and a fatty-acyl reductase.

  • Patent number: 11162111
    Abstract: Wax esters (WE) and triacylglycerols (TAG) can be accumulated in large amounts in plant cells. The present invention relates to insect pheromone precursors which are produced as components of WE or TAG in plants. Further the invention concerns means and methods for the production of plant cells producing WE and/or TAG containing insect pheromone precursors in form of either a fatty acid or a fatty alcohol. Said method uses plants where wax esters are modified by desaturase, fatty acyl reductase and wax ester synthase or the triacylglycerol is modified by a desaturase. Finally the insect pheromone precursors can be extracted and used in the manufacturing of insect pheromones from WE and TAG.
