| Outline of Final Research Achievements |
The computational pipeline was developed to comprehensively identify the animal and/or fish species based on DNA analysis of environmental water samples from sea, river, etc. The pipeline conducts animal metabarcoding analysis using partial mitochondrial 12S rRNA gene (170 bp) amplified from fish- and animal-related water suspensions, in which the quality filtering and the Blast-based species assignment of more than ten million sequences were automated. In addition, the pipeline enables LOD score-based evaluation of species assignment results and automatic generation of molecular phylogenetic trees that would be useful for analysis of ecological diversity and discovery of new species.
