Long amplicon HiFi sequencing for mitochondrial DNA genomes.

Long-read sequencing technology is a powerful approach with application in various genetic and genomic research. Herein, we developed the pipeline for long amplicon high-fidelity (HiFi) sequencing and then applied it for sequencing mitochondrial DNA (mtDNA) genomes from pools of 79 Tibetan Mastiffs. We amplified the mtDNA genome with long-range PCR using two pairs of primers.

The high diversity of SARS-CoV-2-related coronaviruses in pangolins alerts potential ecological risks.

Understanding the zoonotic origin and evolution history of SARS-CoV-2 will provide critical insights for alerting and preventing future outbreaks. A significant gap remains for the possible role of pangolins as a reservoir of SARS-CoV-2 related coronaviruses (SC2r-CoVs). Here, we screened SC2r-CoVs in 172 samples from 163 pangolin individuals of four species, and detected positive signals in muscles of four and, for the first time, one .
