Abstract:
This invention relates to finding that plant growth is directly affected by alterations in the expression of amino acid transporters that mediate the uptake of amino acids from the environment. Methods of modulating plant growth by modulation of amino acid transporter expression are provided.
Abstract:
Methods for Increasing Plant Growth This invention relates to methods for increasing growth and biomass accumulation in woody perennial plants, in particular in trees and other forestry crops, by increasing sucrose-phosphate synthase (SPS) activity in the plant, for example, by expression of a heterologous nucleic acid encoding an SPS polypeptide.
Abstract:
A transgenic plant exhibiting an improved biomass related property, such as an altered lignin content, lignin composition or extractability of lignin, or an altered fibre length, or a combination thereof, said alteration determined by comparison to the corresponding property of the wild-type of the same species, can be achieved by modifying the expression of a pectin methyl esterase (PME) gene in at least one cell of said plant. The down-regulation of PttPMEI (GenBank Accession No. AJ277547) has been shown to result in a fibre length increase of about 5 % and the up- regulation of said gene correspondingly a reduction of about 7 %. Transgenic plants exhibiting altered biomass related properties and methods for their production are disclosed.
Abstract:
This invention relates to a plant regulatory factor (termed APL) which modulates the formation of phloem and xylem in the plant vascular system and which may be useful in altering the vasculature of plants. Isolated APL polypeptides and nucleic acids are provided, along with methods of use, for example in altering the development of phloem/xylem in a plant.
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 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:
The invention relates to methods for increasing saccharification potential in a plant, comprising overexpressing a polynucleotide encoding an acetyl xylan esterase polypeptide in at least one cell type in said plant. The invention further relates to methods for producing genetically modified plants overexpressing a polynucleotide encoding an acetyl xylan esterase polypeptide, as well as to genetically modified plants produced by such methods.
Abstract:
The present invention pertains to processes for preparing granules comprising cellulose-containing fibers and biocomposites comprising disintegrated fibers, granulesand biocomposites produced by the processes of the invention, as well as uses of said granules in methods for producing biocomposites comprising disintegrated fibers.
Abstract:
The present invention relates to a method for the preparation of polymer shells, preferably composed of cellulose or hemicellulose, comprising the steps of dissolving the polymer component in a first solvent, preferably an organic solvent and precipitating the polymer component by contacting the first solution with a second solvent, which second solvent has a polar character, and in which second solvent the polymer component is essentially insoluble, thereby obtaining polymer shells. Moreover, the invention refers to the polymer shells as such, having permeable and responsive properties, as well as various applications comprising such polymer shells within the fields of drug delivery, separation techniques, and inter alia filling material.
