Abstract

Severe acute respiratory syndrome coronavirus (SARS-CoV) was discovered as a novel pathogen in the 2002-2003 SARS epidemic. The emergence and disappearance of this pathogen have brought questions regarding its source and evolution. Within the genome sequences of 281 SARS-CoVs, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and SARS-related CoVs (SARSr-CoVs), a ~430 bp genomic region (from 27 701 bp to 28 131 bp in AY390556.1) with regular variations was investigated. This ~430 bp region overlaps with the ORF8 gene and is prone to deletions and nucleotide substitutions. Its complexity suggested the need for a new genotyping method for coronaviruses related to SARS-similar coronaviruses (SARS-CoV, SARSr-CoV, and SARS-CoV-2). Bat SARSr-CoV presented 3 genotypes, of which type 0 is only seen in bat SARSr-CoV, type I is present in SARS in the early phase, and type II is found in all SARS-CoV-2. This genotyping also shows potential usage in distinguishing the SARS-similar coronaviruses from different hosts and geographic areas. This genomic region has important implications for predicting the epidemic trend and studying the evolution of coronavirus.
