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 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 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. 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.

Abstract:
La invención se refiere a un método para producir una planta o planta leñosa genéticamente modificada con propiedades de crecimiento mejoradas (en términos de biomasa y calidad de la madera) en comparación con una planta o planta leñosa tipo salvaje no genéticamente modificada correspondiente, comprendiendo dicho método alterar el nivel de expresión de un polipéptido en una célula vegetal o célula de planta leñosa; una planta o planta leñosa; o una parte de la misma.
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.
