Outline of Final Research Achievements

I have developed a method to simultaneously detect genes (transcripts) common to all organisms, from prokaryotic bacteria to eukaryotic whales, by full-length sequencing, and to identify all organisms living in a given environment. Compared to the previous method, this method can estimate the classification of organisms and functional information with high accuracy, and can improve the bias of diversity caused by gene amplification by PCR. Since rRNA is abundant in extracted RNA, this method consists of the following elemental technologies: securing the necessary amount of cDNA from RNA without PCR by reverse transcription alone, and decoding the nucleotide sequence with a long read sequencer.

Academic Significance and Societal Importance of the Research Achievements

現在、自然環境に生息する動植物の種類を調査する方法として、環境DNAが注目されている。なぜなら、直接的に動植物を採集する必要が無いので、環境への悪影響が小さいと考えられているからだ。一方、環境DNAで使われている分析手法には改良すべき点がある。それは、魚類や昆虫類など、特定の分類群単位でしか同時に分析できない点である。本研究では、この点を改良し、原核生物のバクテリアから真核生物のクジラまで、全生物を同時に分析できる手法を開発した。
