(English Abstract)
Rapid advances in the next-generation sequencing technologies have enabled the accumulation of sequencing data from various species. However, the generation of high-quality Y chromosome assemblies in mammals has lagged because of the genomic complexity of the Y chromosome. This study focuses on developing a method of improving the quality of Y chromosome assembly, which performs the Y chromosome assembly using only the mapped reads to the Y chromosome (Y-reads) in a reference genome. This method was applied to a specific pig breed and a waterbuck with different types of sequencing data. When the assembly was performed with the Y-reads, the total length of the scaffolds and the total length of the aligned scaffolds to the Y chromosome assembly of the reference genome increased as compared to the result from a traditional approach. In addition. in the case of the pig breed with more types of sequencing data, both the size of the largest scaffold and the total length of high-quality scaffolds increased by about two folds compared to results from the traditional approach. These results clearly show the potential of our method in the production of high-quality Y chromosome assemblies for various mammal species.
