Using a third consensus-based approach for identifying recombinant regions in individual sequenceswith six different recombination detection methods in RDP5 (ref. However, the coronavirus isolated from pangolin is similar at 99% in a specific region of the S protein, which corresponds to the 74 amino acids involved in the ACE (Angiotensin Converting Enzyme . and D.L.R. Pangolin was developed to implement the dynamic nomenclature of SARS-CoV-2 lineages, known as the Pango nomenclature. Li, X. et al. Aiewsakun, P. & Katzourakis, A. Time-dependent rate phenomenon in viruses. To obtain Below, we report divergence time estimates based on the HCoV-OC43-centred rate prior for NRR1, NRR2 and NRA3 and summarize corresponding estimates for the MERS-CoV-centred rate priors in Extended Data Fig. Press, H.) 3964 (Springer, 2009). Extended Data Fig. Evol. 3) clusters with viruses from provinces in the centre, east and northeast of China. Google Scholar. Nature 583, 286289 (2020). Wong, A. C. P., Li, X., Lau, S. K. P. & Woo, P. C. Y. Evolutionary origins of the SARS-CoV-2 sarbecovirus lineage responsible for the COVID-19 pandemic, https://doi.org/10.1038/s41564-020-0771-4. While pangolins could be acting as intermediate hosts for bat viruses to get into humansthey develop severe respiratory disease38 and commonly come into contact with people through traffickingthere is no evidence that pangolin infection is a requirement for bat viruses to cross into humans. In other words, a true breakpoint is less likely to be called as such (this is breakpoint-conservative), and thus the construction of a non-recombining region may contain true recombination breakpoints (with insufficient evidence to call them as such). All three approaches to removal of recombinant genomic segments point to a single ancestral lineage for SARS-CoV-2 and RaTG13. It allows a user to assign a SARS-CoV-2 genome sequence the most likely lineage (Pango lineage) to SARS-CoV-2 query sequences.

Maciej F. Boni, Philippe Lemey, Andrew Rambaut or David L. Robertson. wrote the first draft of the manuscript, and all authors contributed to manuscript editing. CNN . This long divergence period suggests there are unsampled virus lineages circulating in horseshoe bats that have zoonotic potential due to the ancestral position of the human-adapted contact residues in the SARS-CoV-2 RBD. These shy, quirky but cute mammals are one of the most heavily trafficked yet least understood animals in the world. 110. Sequences are colour-coded by province according to the map. P.L. 82, 48074811 (2008). Genetic lineages of SARS-CoV-2 have been emerging and circulating around the world since the beginning of the COVID-19 pandemic. Calibration of priors can be performed using other coronaviruses (SARS-CoV, MERS-CoV and HCoV-OC43), but estimated rates vary with the timescale of sample collection. Biol. The consistency of the posterior rates for the different prior means also implies that the data do contribute to the evolutionary rate estimate, despite the fact that a temporal signal was visually not apparent (Extended Data Fig. 11,12,13,22,28)a signal that suggests recombinationthe divergence patterns in the Sprotein do not show evidence of recombination between the lineage leading to SARS-CoV-2 and known sarbecoviruses. We compiled a set of 69SARS-CoV genomes including 58 sampled from humans and 11 sampled from civets and raccoon dogs. Note that six of these sequences fall under the terms of use of the GISAID platform. An initial genomic sequence analysis found that the reemergence of COVID-19 in New Zealand was caused by a SARS-CoV-2 from the (now ancestral) lineage B.1.1.1 of the pangolin nomenclature ( 17 ). The canine viral genome was excluded from the Bayesian phylogenetic analyses because temporal signal analyses (see below) indicated that it was an outlier. NTD, N-terminal domain; CTD, C-terminal domain. Divergence time estimates based on the HCoV-OC43-centred rate prior for the separate BFRs (Supplementary Table 3) show consistency in TMRCA estimates across the genome. 25, 3548 (2017). He, B. et al. Unlike other viruses that have emerged in the past two decades, coronaviruses are highly recombinogenic14,15,16. Add entries for pangolin-data/-assignment 1.18.1.1 (, Really add a document on testing strategy. RegionB is 5,525nt long. Green boxplots show the TMRCA estimate for the RaTG13/SARS-CoV-2 lineage and its most closely related pangolin lineage (Guangdong 2019), with the light and dark coloured version based on the HCoV-OC43 and MERS-CoV centred priors, respectively. PLoS Pathog. The genetic distances between SARS-CoV-2 and RaTG13 (bottom) demonstrate that their relationship is consistent across all regions except for the variable loop. The Artic Network receives funding from the Wellcome Trust through project no. Xiao, K. et al. These residues are also in the Pangolin Guangdong 2019 sequence. Extensive diversity of coronaviruses in bats from China. COVID-19 lineage names can be confusing to navigate; there are many aliases and if you want to catch them all to examine further in data analyses it helps to Allen O'Brien on LinkedIn: #r #rstudio #rstats #pangolin #covid19 #datascience #epidemiology The construction of NRR1 is the most conservative as it is least likely to contain any remaining recombination signals. This dataset comprises an updated version of that used in Hon et al.15 and includes a cluster of genomes sampled in late 2003 and early 2004, but the evolutionary rate estimate without this cluster (0.00175 substitutions per siteyr1 (0.00117,0.00229)) is consistent with the complete dataset (0.00169 substitutions per siteyr1, (0.00131,0.00205)). The fact that these estimates lie between the rates for MERS-CoV and HCoV-OC43 is consistent with the intermediate sampling time range of about 18years (Fig. Boni, M. F., Zhou, Y., Taubenberger, J. K. & Holmes, E. C. Homologous recombination is very rare or absent in human influenza A virus. B.W.P. S. China corresponds to Guangxi, Yunnan, Guizhou and Guangdong provinces. Given what was known about the origins of SARS, as well as identification of SARS-like viruses circulating in bats that had binding sites adapted to human receptors29,30,31, appropriate measures should have been in place for immediate control of outbreaks of novel coronaviruses. We showed that severe acute respiratory syndrome coronavirus 2 is probably a novel recombinant virus. The command line tool is open source software available under the GNU General Public License v3.0. Viruses 11, 174 (2019). PubMed Central SARS-CoV-2 is an appropriate name for the new coronavirus. Suchard, M. A. et al. & Andersen, K. G. The evolution of Ebola virus: insights from the 20132016 epidemic. As a proxy, it would be possible to model the long-term purifying selection dynamics as a major source of time-dependent rates43,44,52, but this is beyond the scope of the current study. PubMed Central 1c). Syst. Across a large region of the virus genome, corresponding approximately to ORF1b, it did not cluster with any of the known bat coronaviruses indicating that recombination probably played a role in the evolutionary history of these viruses5,7. obtained the genome sequences of 10 SARS-CoV-2 virus strains through nanopore sequencing of nasopharyngeal swabs in Malta and analyzed the assembled genome with pangolin software, and the results showed that these virus strains were assigned to B.1 lineage, indicating that SARS-CoV-2 was widely spread in Europe (Biazzo et al., 2021). Because these subclades had different phylogenetic relationships in regionD (Supplementary Fig. In early January, the aetiological agent of the pneumonia cases was found to be a coronavirus3, subsequently named SARS-CoV-2 by an International Committee on Taxonomy of Viruses (ICTV) Study Group4 and also named hCoV-19 by Wu et al.5. Specifically, using a formal Bayesian approach42 (see Methods), we estimate a fast evolutionary rate (0.00169 substitutions per siteyr1, 95% highest posterior density (HPD) interval (0.00131,0.00205)) for SARS viruses sampled over a limited timescale (1year), a slower rate (0.00078 (0.00063,0.00092) substitutions per siteyr1) for MERS-CoV on a timescale of about 4years and the slowest rate (0.00024 (0.00019,0.00029) substitutions per siteyr1) for HCoV-OC43 over almost five decades. Nature 579, 265269 (2020). This is notable because the variable-loop region contains the six key contact residues in the RBD that give SARS-CoV-2 its ACE2-binding specificity27,37. and P.L.) Chernomor, O. et al. Extended Data Fig. with an alignment on which an initial recombination analysis was done. Bioinformatics 28, 32483256 (2012). These means are based on the mean rates estimated for MERS-CoV and HCoV-OC43, respectively, while the standard deviations are set ten times higher than empirical values to allow greater prior uncertainty and avoid strong bias (Extended Data Fig. We compiled a dataset including 27human coronavirus OC43 virus genomes and ten related animal virus genomes (six bovine, three white-tailed deer and one canine virus). Yuan, J. et al. Su, S. et al. We demonstrate that the sarbecoviruses circulating in horseshoe bats have complex recombination histories as reported by others15,20,21,22,23,24,25,26. Bioinformatics 22, 26882690 (2006). Nature 558, 180182 (2018). Sequencing from Malayan pangolins collected during anti-smuggling operations in southern China detected coronavirus lineages related to SARS-CoV-2. While there is evidence of positive selection in the sarbecovirus lineage leading to RaTG13/SARS-CoV-2 (ref. Nature 583, 282285 (2020). We thank T. Bedford for providing M.F.B.

BEAST inferences made use of the BEAGLE v.3 library68 for efficient likelihood computations. Scientists defined the pangolin lineage of this variant to be B.1.1.523 and it was originally recognized as a variant under monitoring on July 14, 2021. Region A has been shortened to A (5,017nt) based on potential recombination signals within the region. PLoS ONE 5, e10434 (2010). =0.00075 and one with a mean of 0.00024 and s.d. J. Virol.
