Abstract: The present invention relates to methods to modify at least one target locus in a plant cell, comprising, providing a plant cell with one or more target loci and one or more donor loci, followed by induction of homologous recombination between homologous regions of at least one target locus and at least one donor locus by at least one rare cleaving nuclease. The present invention related also to target loci, donor loci and nuclease loci used in these methods, and plant cells, plants and plant parts comprising these target loci, donor loci, nuclease loci and/or the recombined loci.

Abstract: The invention provides polynucleotides encoding N-terminal truncated forms of sucrose isomerase polypeptides which are capable of conferring increased nematode resistance in a plant. The invention also provides methods of producing transgenic plants with increased nematode resistance, seeds of such transgenic plants, and expression vectors, all of which comprise the polynucleotides of the invention.

Abstract: The invention relates to improved recombination systems and methods for eliminating maker sequences from the genome of plants. Particularly the invention is based on use of an expression cassette comprising the parsley ubiquitin promoter, and operably linked thereto a nucleic acid sequence coding for a sequence specific DNA-endonuclease.
