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: Important aims in nearly all tree-breeding programs around the world are to produce plants with increased growth rates and stem volumes, and shorter rotation times. Such trees would yield more biomass per area unit. Here the present inventors have shown that when over-expressing a key regulatory gene in the biosynthesis of the plant hormone gibberellin (GA) in hybrid aspen (Populus tremula×P. tremuloides), improvements in valuable traits such as growth rate and biomass are obtained. In addition, these trees also have longer xylem fibres than unmodified wild type plants. Long fibers are very desirable in the production of strong paper, but it has not (as yet) proved possible to influence this trait by traditional breeding techniques. A further advantage of the present invention is that it may reduce or eliminate the use of growth influencing chemicals in forestry.

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: This invention relates to fertilizer and herbicide compositions. The present invention provides a composition for selective fertilization of a transgenic plant comprising a polypeptide which metabolizes a D-amino acid substrate; said composition comprising said D-amino acid substrate. Another aspect of the present invention provides a selective herbicide composition comprising a D-amino acid. Such a herbicide will inhibit or reduce the growth of plants which do not contain the appropriate D-amino acid metabolizing enzyme, while the growth of transgenic plants which are able to metabolize the D-amino acid will be unaffected or, more preferably, be increased or enhanced. Methods and means are also provided for selectively modulating the growth and stress tolerance such plants using D-amino acids.

Abstract: This invention relates to plants and plant cells which express heterologous D-amino acid metabolizing 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 of such plants using D-amino acids. The methods can be used either for detoxification of phytotoxic D-amino acids such as D-alanine and D-serine, thereby allowing for selection of plants comprising said D-amino acid metabolizing enzymes, or for enhancing toxicity of lesser phytotoxic D-amino acids such as D-isoleucine, thereby allowing for selection of plants not comprising said D-amino acid metabolizing enzymes.
