  • VEGETABILE MATERIAL, PLANTS AND A METHOD OF PRODUCING A PLANT HAVING ALTERED LIGNIN PROPERTIES
    Publication number: 20140298509
    Abstract: The present invention is related to a set of genes, which when modified in plants gives altered lignin properties. The invention provides DNA construct such as a vector useful in the method of the invention. Further, the invention relates to a plant cell or plant progeny of the plants and wood produced by the plants according to the invention Lower lignin levels will result in improved saccharification for bio-refining and ethanol production and improved pulp and paper. Increased lignin levels will utilise lignin properties for energy production. The genes and DNA constructs may be used for the identification of plants having altered lignin characteristics as compared to the wild-type. According to the invention genes and DNA constructs may also be used as candidate genes in marker assisted breeding.

  • Yeast strains producing cellulolytic enzymes and methods and means for constructing them
    Patent number: 5766915
    Abstract: Functional derivatives of endoglucanase I (EGI), and the cloning and recombinant expression thereof, are described.
    Type: Grant

  • Method of making endoglucanase I
    Patent number: 5529919
    Abstract: Described are methods and means for the construction of strains of yeast capable of producing cellulolytic enzymes. This is achieved by the transfer of chromosomal genes or cDNA copies of mRNAs coding for cellulolytic enzymes isolated from the fungus Trichoderma reesei to yeast cells using recombinant DNA vectors capable of replicating in yeast. The correct expression of these cellulolytic genes in yeast leads to the production of cellulolytic enzymes which are secreted from the cell. This allows the yeast to hydrolyze 3-1,4-glucan substrates such as cellulose.

  • Yeast strains producing cellulolytic enzymes and methods and means for constructing them
    Patent number: 4894338
    Abstract: The full length DNA sequence encoding the mature cellobiohydrolase II(CHBII), as well as the DNA sequence encoding the CBHII signal sequence, have been isolated and cloned from the fungus Trichoderma reesei. Recombinant vectors comprising these sequences, and yeast hosts transformed with such vectors are disclosed. Also disclosed are methods for constructing the vectors and hosts according to the invention, as well as methods for expressing the disclosed sequences. CBHII is involved in hydrolysis of cellulose.
