Eukaryotic microalgae genetically modified strains with improved triglyceride productivity and use thereof

摘要

It is an object of the present invention to provide the eukaryotic microalgae, which have been genetically modified such that larger amounts of assimilation products produced by photosynthesis are directed to the synthesis of triglyceride (=triacylglycerol; TAG), and specifically, the present invention relates to a genetically modified strain of eukaryotic microalgae, in which a gene encoding an AGL1 protein is highly expressed, or a gene encoding an FAT1 protein and/or a gene encoding a DGAT2 protein are further highly expressed, as well as the gene encoding an AGL1 protein, wherein TAG productivity is improved in comparison to the parent strain thereof.
