Abstract: The invention provides a transgenic plant, which expresses a transgene encoding a citrate synthase (CS) wherein the transgenic plant seed of the invention is characterized by increased yield and/or enhanced levels of protein, essential amino acids or oil, when compared to an isoline that does not express the transgene; and also provides methods of producing transgenic plants with economically relevant traits and provides expression vectors comprising polynucleotides encoding Citrate Synthase.

Abstract: The present invention relates to expression cassettes comprising at least one transcription regulating nucleotide sequence obtainable from the group of genes of monocotyle-donous plants consisting of caffeoyl-CoA-O-methyltransferase genes, C8,7-sterol isomerase genes, hydroxyproline-rich glycoprotein (HRGP) genes, lactate dehydrogenase genes, and chloroplast protein 12 like genes. More preferably the transcription regulating sequences are obtainable from Zea mays or Oryza sativa. The transcription regulating sequences are especially useful for root/kernel-preferential, leaf/endosperm-preferential, root/silk/kernel-preferential, or constitutive expression.

Abstract: The present invention relates to a process for production of unsaturated ?-3-fatty acids and to a process for production of triglycerides with an elevated content of unsaturated fatty acids, especially of ?-3-fatty acids having more than three double bonds. The invention relates to the production of a transgenic organism, preferably of a transgenic plant or of a transgenic microorganism, with an elevated content of unsaturated ?-3-fatty acids, oils or lipids having ?-3-double bonds as the result of the expression of an ?-3-desaturase from fungi of the family Pythiaceae such as the genus Phytophtora, for example of the genus and species Phytophtora infestans.
