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 present invention relates to a method for obtaining a genetically modified plant having increased yield and improved drought tolerance, as compared to a wild type control plant of the same species, comprising: Modifying the genomic DNA in at least one cell of said plant species to increase expression of a FTSHi3 gene thereby obtaining a genetically modified cell; generating a plant from the genetically modified cell to obtain a genetically modified plant; growing said genetically modified plant under conditions which permit development of a plant; and selecting a genetically modified plant having improved drought tolerance. The invention also relates to plants obtainableby such methods, and genetically modified plants exhibiting at least 50% increased expression of a FTSHi3 gene as compared to the wild-type control plant of the same species.

Methods and uses of a sowing unit.
Abstract:
The present invention provides a method for the production of a superhydrophobic film, surface or material comprising the steps of:(i) providing a composition comprising a hydrophobic substance and a hydrophilic solvent, the hydrophilic solvent being a liquid at a temperature of 25 °C and atmospheric pressure; and (ii) spraying the composition towards a substrate for deposition of a solid residue onto the surface of the substrate for generation of the superhydrophobic film, surface or material;wherein the temperature of the composition is higher that the temperature of the substrate when carrying out step (ii).A composition, use of the composition and a substrate is also provided.
Abstract:
Methods and devices for dispersion of assemblies of biological material (such as plant embryogenic mass, plant tissue, cultured plant cells, animal tissue and/or cultured animal cells)suspended in a liquid are disclosed. The methods comprise i) subjecting the assemblies of biological material to fluid dynamics forces causing axially extensional strain and radially compressional strain and ii) subjecting the assemblies of biological material to fluid dynamics forces causing axially compressional strain and radially extensional strain fluid dynamics and iii) repeating said steps i) and ii) in sequence until assemblies of biological material is dispersed into the desired smaller size. The devices may comprise a flow channel arranged in a loop configuration for re-circulation in the flow channel, the flow channel including at least one constriction, such that the assemblies of biological material flowing through the flow channel are first subjected to axially extensional strain and radially compressional strain, and then to axially compressional strain and radially extensional strain from fluid dynamics forces.
Abstract:
This invention relates to methods of increasing the growth and/or biomass of plants by partially suppressing the expression of a SHORT-ROOT [SHR) polypeptide, such as AtSHR or PtSHRl . Manipulation of SHORT-ROOT expression may be useful, for example, in accelerating growth and increasing biomass production in transgenic plants.
Abstract:
The present invention relates to ferromagnetic materials based on nano-sized bacterial cellulose templates. More specifically, the present invention provides an agglomerate free magnetic nanoparticle cellulose material and a method of forming such magnetic nanoparticle cellulose material. Further, the magnetic nonoparticles are physically attached on the cellulose material and evenly distribute.
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 a method 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. 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 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 a novel group of copolymers comprising a soluble carbohydrate polymer (SCP), which typically is a non-starch carbohydrate, and a macromolecule covalently attached to the SCP. The macromolecule may e.g. be a hydrophobic copolymer, a polyelectrolyte polymer or a biodegradable polymer. The present invention furthermore relates to a method of preparing the copolymer, products comprising the copolymer, and to methods of preparing the products comprising the copolymer. The products comprising a copolymer are for example a polymeric carbohydrate material (PCM) modified by attachment of a copolymer, and a composite material comprising the modified PCM.
