Abstract:
The present invention pertains to a novel and extensive analytical platform for selecting genes with a possible commercial phenotype from a large group of candidate genes identified using tools in bioinformatics, data from EST sequencing and DNA array. The analytical platform is concentrated on analyses of fiber length and/or width and growth behavior based on a combination of multiple criteria. An object of the present invention relates to a method of producing a transgenic plant having an increased fibre length and/or width compared to its wild type. The method comprises altering in the plant the level of a gene product of at least one gene specifically expressed during different phases of wood formation phases. Further aspects of the invention provide a plant cell or plant progeny of a transgenic plant comprising a recombinant polynucleotide according to the invention. Other aspects pertain to wood produced by a transgenic plant of the invention as well as a DNA construct comprising a nucleotide sequence of the invention and a plant cell or plant progeny comprising the DNA construct.
Abstract:
The present invention relates to genetically modified plants comprising a heterologous nucleic acid construct comprising a promoter sequence operably linked to a coding sequence encoding a gene product. The invention further relates to methods for producing such plants.
Abstract:
Tissue specific promoters (SEQ. ID. NO. 1 - 5) are disclosed, these being preferentially expressed in the xylem tissue of woody plants. These promoters are used e.g. to specifically regulate gene expression in xylem tissue and alter xylem properties in plants. Transgenic plants, exhibiting modified xylem properties can be produced using these promoters.

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.

Abstract:
The invention relates to a method for preventing and/or suppressing growth of transgenic plants comprising a transgenic expression cassette for a D-amino acid oxidase, which are grown on a field, in subsequent seasons among a population of other plants on said field or neighboring fields based on selective killing of the transgenic plants by application of a D-amino acid (e.g. D-isoleucine) which is metabolized by said D-amino acid in said transgenic plants into a phytotoxic compound.
Abstract:
The present invention relates to genetically modified woody plants comprising a heterologous nucleic acid construct comprising a promoter sequence operably linked to a coding sequence encoding a gibberellin 20-oxidase gene product, wherein the promoter is preferentially or specifically expressed in meristematic tissue of said plant. The invention further relates to methods for producing such plants and to certain nucleic acid molecules useful as promoters.
