Abstract: The invention relates to the isolation of promoters from corn capable of directing transcription of an operably linked foreign DNA sequence preferentially, selectively or exclusively in the roots of plants, such as corn plants. The invention also relates to the use of chimeric genes for the preferential or selective expression of biologically active RNA of interest in the roots of plants, such as corn plants. Plants, such as corn plants, comprising corn root preferential or selective promoters operably linked to a foreign DNA sequence which, upon transcription, yield biologically active RNA preferentially or selectively in the roots of plants are also provided.

Abstract: The invention pertains to transgenic cotton plants, plant material and seeds, characterized by harboring a specific transformation event, particularly by the presence of a gene encoding a protein that confers herbicide tolerance, at a specific location in the cotton genome. The cotton plants of the invention combine the herbicide tolerant phenotype with optimal agronomic performance.

Abstract: A method is described for the exact removal of a selected subfragment from a DNA molecule by intrachromosomal recombination between two directly repeated DNA sequences using a rare-cleaving double stranded break inducing DNA endonuclease expressed under control of a micro-spore specific promoter. This method can be applied in a method for the exact exchange of a target DNA fragment for a DNA fragment of interest in plant cells and plants.
Abstract: Plants made resistant to insects by transforming their nuclear genome with two or more DNA sequences, each encoding a different non-competitively binding B. thuringiensis protoxin or insecticidal part thereof, preferably the toxin thereof.

Abstract: Methods are provided for increasing the resistance of plants to hypoxic or anoxic conditions. Such methods may be applied to increase the penetrance of plant roots in the growth medium or into soil. The methods according to the invention may include providing plants with a stress tolerance gene. Similar effects can be obtained by applying chemical compounds, including neonicotinoid compounds, to the plants.
Abstract: The invention provides improved methods and means for introducing inhibitory RNA into plant cells. The invention also provides kits comprising viral RNA vectors derived from satellite viruses and corresponding helper viruses for the introduction of inhibitory RNA into plant cells and plants. Further, the invention comprises methods for obtaining an enhanced or improved gene-silencing phenotype.

Abstract: Four novel Bacillus thuringiensis strains, which are deposited at the BCCM-LMG under accession nos. LMG P-12592, LMG P-12593, LMG P-12594, and LMG P-13493, produce new crystal proteins during sporulation that are toxic to Lepidoptera, more particularly against Noctuidae such as Spodoptera spp. and Agrotis ipsilon, against Pyralidae such as Ostrinta nubilalis, and against Yponomeutidae such as Plutella xylostella, and that are encoded by a novel gene. The crystal proteins contain protoxins, which can yield a toxin as trypsin-digestion product. A plant, the genome of which is transformed with a DNA sequence that comes from either one of the strains and that encodes its respective toxin, is resistant to Lepidoptera. Each strain, itself, or its crystals, crystal proteins, protoxin or toxin can be used as the active ingredient in an insecticidal composition for combatting Lepidoptera.
