Abstract:
The invention relates to a method for producing a genetically modified woody plant with improved growth properties (in terms of biomass and/or wood density) as compared to a corresponding non-genetically modified wild type plant or woody plant, said method comprising altering the level of expression of a polypeptide in a woody plant cell; a woody plant; or a part thereof.
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. An aspect of the invention provides methods of producing a transgenic plant having an increased growth 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. This may be done with transgenic methods or by specific crossing methods. Further aspects of the invention provide a plant cell or plant progeny and wood having modulated gene expression according to the invention. Other aspects pertain a DNA construct comprising a nucleotide sequence of the invention and a plant cell or plant progeny comprising the DNA construct.
Abstract:
This invention relates to the modulation of growth and wood quality in trees by co-expression of a growth promoting polypeptide, for example a plant hormone biosynthesis polypeptide, for example a GA20 oxidase, and a wood quality polypeptide, for example a pectin methyl esterase, expansin or sucrose phosphate synthase.
Abstract:
The invention relates to improved construct and methods for eliminating maker sequences from the genome of plants, based on dual-function selection marker which - depending on the employed compound - can act as both negative and counter-selection marker.
Abstract:
This invention relates to plants and plant cells which express heterologous D-amino acid metabolising enzymes and may therefore employ D-amino acids as a source of nitrogen. Methods and means are provided for selectively modulating the growth and stress tolerance such plants using D-amino acids.
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:
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.
