| Outline of Final Research Achievements |
Major marine primary producers such as diatoms and haptophytes have red-algal-derived-chloroplast acquired through secondary endosymbiotic events. Due to different evolutional origin, these marine secondary algae have distinct features in carbon metabolism compared with the well-studied green lineage. Here I characterized putative metabolic enzymes involved in the oil accumulation in a marine diatom. As a result, I revealed that some glycolytic enzymes which are usually absent in the chloroplast were located in the chloroplast of a diatom. The chloroplastic glycolytic pathway is expected to supply precursors for oil biosynthesis. I tried to generate overexpression and suppression mutant of the chloroplatic glycolytic enzymes. I could successfully obtain overexpression mutant while no RNAi mutants have been obtained yet. The overexpression mutant will be useful to reveal the entire pathway of oil synthesis and accumulation in marine diatom.
