GENETICALLY MODIFIED STRAIN OF EUKARYOTIC MICROALGA HAVING IMPROVED TRIGLYCERIDE PRODUCTIVITY, AND USE THEREOF

摘要

The objective of the present invention is to provide a eukaryotic microalga which has been genetically manipulated so that more of the anabolites produced by photosynthesis are directed into triglyceride (triacylglycerol, TAG) synthesis. Specifically, the present invention concerns a genetically modified strain of eukaryotic microalga in which the gene that encodes the AGL1 protein is expressed at high levels, or, in addition to said gene, the gene that encodes the FAT1 protein and/or the gene that encodes the DGAT2 protein are also expressed in high levels, wherein TAG productivity is improved compared to the parent strain.
