Abstract:
The invention relates to a method for producing a genetically modified plant or woody plant with improved growth properties (in terms of biomass and wood quality) 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 plant cell or woody plant cell; a plant or woody plant; or a part thereof.
Abstract:
The invention relates to methods for producing a plant with altered lignin content by genetically manipulating expression of a PIRIN gene. The said method comprises (a) altering expression of a gene encoding a PIRIN2 polypeptide in the plant; and/or (b) altering expression of a gene encoding a PIRIN4 polypeptide in the plant. A plant with reduced lignin content is produced by increasing expression of a gene encoding a PIRIN2 polypeptide in the plant or decreasing expression of a gene encoding a PIRIN4 polypeptide in the plant. The invention further relates to genetically modified plants produced by the said methods.
Abstract:
An 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 is disclosed. Methods are disclosed for producing a transgenic plant having an increased growth compared to its wild type by 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. Plant cells or plant progeny and wood having modulated gene expression are also disclosed. A DNA construct with a nucleotide sequence for a gene producing a transgenic plant having an increased growth compared to its wild type and a plant cell or plant progeny having the DNA construct are also disclosed.
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 inventionLower 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 present invention relates to methods and systems for obtaining a plantlet from a plurality of somatic plant embryos, and to the use of a compressible and resilient solid substrate comprising a plurality of hydrophilic and biodegradable polymer fibres, as a germination substrate in a method for germination of a somatic plant embryo.
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.
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:
A sowing unit including water-absorbing material, an enclosure and a seed, wherein the water-absorbing material includes a hygroscopic negatively-charged material capable of binding a positively charged nutrient ion selected from NH4+, L-arginine, L-lysine and L-histidine; and optionally a nutrient including a positively charged nutrient ion selected from K+, NH4+, L-arginine, L-lysine and L-histidine. Methods and uses of the sowing unit are described.
Abstract:
Transcription factor polynucleotides and polypeptides incorporated into nucleic acid constructs, including expression vectors, have been introduced into plants and were ectopically expressed. Transgenic plants transformed with many of these constructs have been shown to have increased tolerance to an abiotic stress (in some cases, to more than one abiotic stress), increased growth, and/or increased biomass. The abiotic stress may include, for example, salt, hyperosmotic stress, water deficit, heat, cold, drought, and/or low nutrient conditions.
