Amylopectin potato starch with improved stability against retrogradation and improved freeze and thaw stability, wherein it contains more than 99% amylopectin, preferably 100% amylopectin, is disclosed, as well as a method for the production of a potato () containing said amylopectin potato starch, wherein said method involves homology-directed mutagenesis using CRISPR/nuclease technology and comprises the following steps:

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.
