  • Publication number: 20190376073
    Abstract: Compositions and methods are provided for stacking multiple independent transgenic loci into the genome of a plant. Compositions include plants, seeds or plant cells comprising at least one transgenic target site and at least one genomic locus of interest integrated at different genomic sites within a genomic window. Plant breeding techniques can be employed such that the transgenic target site and the genomic locus of interest can be bred together. In this way, multiple independent transgene integrations can be generated within a genomic window to create a complex trait locus. The complex trait locus is designed such that the transgenic target sites and/or genomic loci of interest can segregate independently of each other, thus providing the benefit of altering a complex trait locus by breeding-in and breeding-away specific elements. Various methods can also be employed to modify the target sites such that they contain a variety of polynucleotides of interest.

  • Patent number: 10428362
    Abstract: A method is disclosed for hydrolyzing an alpha-1,5 glucosyl-fructose linkage in a saccharide (disaccharide or oligosaccharide) such as leucrose. This method comprises contacting the saccharide with an alpha-glucosidase enzyme such as transglucosidase or glucoamylase under suitable conditions, during which contacting step the enzyme hydrolyzes at least one alpha-1,5 glucosyl-fructose linkage of the saccharide. This method is useful for reducing the amount of leucrose in a filtrate isolated from a glucan synthesis reaction, for example.
