SUMMARY
Aims: To construct a Japanese reference genome sequence
Methods: Sequence data were obtained from each of three healthy Japanese males by the PacBio, Bionano, and Illumina HiSeq platforms. De novo assembly was performed for each individual, and then the three assemblies were integrated by meta-assembly. In addition, the majority variant was adopted by majority vote for the polymorphic sites among the three assemblies. Finally, the meta-scaffolds were anchored by markers from genetic and radiation hybrid maps and integrated as a pseudo-chromosome sequence set.
Participants/Materials: three Japanese male individuals

| Genome Sequence Construction Methods |
1. highly contiguous de novo assembly: 1) PacBio long reads were de novo assembled to yield primary contigs 2) Bionano raw data were also de novo assembled (independent of the PacBio assembly) to yield genome maps 3) the PacBio-derived contigs were scaffolded by the Bionano genome maps 2. Polishing the hybrid scaffolds with Illumina short reads (paired-end) 3. Integrating and filling the gaps of the hybrid scaffolds of each individual with an aid of mate pair Illumina short reads 4. meta-assembly with Metassembler software 5. Anchoring scaffolds to chromosomes with genetic and radiation hybrid maps |
