Abstract: The present invention provides a nucleic acid molecule comprising: DGAT1 promoter or an active fragment thereof, the ammonium transporter promoter or an active fragment thereof, or the putative purine permease promoter or an active fragment thereof; coupled to a gene. The invention further provides a vector including the nucleic acid molecule and cells harboring the nucleic acid molecule.

Abstract: An isolated protein which is at least partially encoded by a polynucleotide sequence encoding a novel acyl-CoA: diacylglycerol acyltransferase 1-like gene (PtDGAT1) from the diatom Phaeodactylum tricomutum is provided together with a composition which includes the isolated protein and a transgenic organism transformed by a polynucleotide encoding same. The invention also provides a method for producing or enhancing the production of oil or triacylglycerols with high saturated fatty acids content.

Abstract: Isolated proteins which are at least partially encoded by polynucleotide sequences encoding novel desaturases are provided together with a composition which includes these isolated proteins. A transgenic plant, a transgenic alga, or a transgenic seed transformed by the polynucleotides encoding proteins which are at least partially encoded by novel desaturases are also provided. The invention also includes a process for making a very long-chain polyunsaturated fatty acid in a transformed cell, a transgenic alga, or a transgenic plant expressing the isolated protein or proteins which are at least partially encoded by the polynucleotide sequences encoding novel ?5, ?6, or ?12 desaturases.

Abstract: The present invention provides a protein, specifically Parietochloris incisa acetohydroxyacid synthase, and methods for producing branched-chain amino acid in a cell. The present invention further provides polypeptides and polynucleotides useful for conferring herbicide resistance in a cell or an organism. In particular, the present invention discloses a mutated acetohydroxyacid synthase which is resistant to herbicides.
