Abstract: A transgenic seed or plant of a corn, cotton, rapeseed or soybean species having a recombinant chromosome with multiple transgenes for imparting traits to said seed or its plant. Useful traits include herbicide tolerance, insect resistance, nematode resistance, viral resistance, tolerance to water deficit, tolerance to nitrogen deficit, enhanced amino acid level in seed, enhanced starch level in seed, enhanced oil level in seed, modified oil composition, and increased yield. Useful recombinant chromosomes are produced with centromere DNA from the plant targeted for transformation or from truncated native chromosomes.

Abstract: The present invention is in the field of plant biochemistry. More specifically the invention relates to nucleic acid sequences from plant cells, in particular, DNA sequences from maize and soybean plants associated with the methionine pathway. The invention encompasses nucleic acid molecules that encode proteins and fragments of proteins. In addition, the invention also encompasses proteins and fragments of proteins so encoded and antibodies capable of binding these proteins or fragments. The invention also relates to methods of using the nucleic acid molecules, proteins and fragments of proteins and antibodies, for example for genome mapping, gene identification and analysis, plant breeding, preparation of constructs for use in plant gene expression and transgenic plants.
