The sizes of the black internal node circles are proportional to the posterior node support. Phylogenetic classification of the whole-genome sequences of SARS-CoV-2 Chernomor, O. et al. Google Scholar. To evaluate the performance procedure, we confirmed that the recombination masking resulted in (1) a markedly different outcome of the PHI test64, (2) removal of well-supported (bootstrap value >95%) incompatible splits in Neighbor-Net65 and (3) a near-complete reduction of mosaic signal as identified by 3SEQ. Lemey, P., Minin, V. N., Bielejec, F., Pond, S. L. K. & Suchard, M. A. A distinct name is needed for the new coronavirus. Correspondence to There are outstanding evolutionary questions on the recent emergence of human coronavirus SARS-CoV-2 including the role of reservoir species, the role of recombination and its time of divergence from animal viruses. Med. Isolation of SARS-CoV-2-related coronavirus from Malayan pangolins. Visual exploration using TempEst39 indicates that there is no evidence for temporal signal in these datasets (Extended Data Fig. Virus Evol. and D.L.R. Nguyen, L.-T., Schmidt, H. A., Von Haeseler, A. Lancet 395, 565574 (2020). These differences reflect the fact that rate estimates can vary considerably with the timescale of measurement, a frequently observed phenomenon in viruses known as time-dependent evolutionary rates41,43,44. Discovery and genetic analysis of novel coronaviruses in least horseshoe bats in southwestern China. Bayesian evaluation of temporal signal in measurably evolving populations. Our approach resulted in similar posterior rates using two different prior means, implying that the sarbecovirus data do inform the rate estimate even though a root-to-tip temporal signal was not apparent. GitHub - cov-lineages/pangolin: Software package for assigning SARS-CoV-2 genome sequences to global lineages. 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. The extent of sarbecovirus recombination history can be illustrated by five phylogenetic trees inferred from BFRs or concatenated adjacent BFRs (Fig. A single 3SEQ run on the genome alignment resulted in 67 out of 68sequences supporting some recombination in the past, with multiple candidate breakpoint ranges listed for each putative recombinant. with an alignment on which an initial recombination analysis was done. Pangolin was developed to implement the dynamic nomenclature of SARS-CoV-2 lineages, known as the Pango nomenclature. 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. A hypothesis of snakes as intermediate hosts of SARS-CoV-2 was posited during the early epidemic phase54, but we found no evidence of this55,56; see Extended Data Fig. A., Lytras, S., Singer, J. PLoS Pathog. Collectively our analyses point to bats being the primary reservoir for the SARS-CoV-2 lineage. [12] =0.00075 and one with a mean of 0.00024 and s.d. Now, the two researchers used genomic sequencing to compare the DNA of the new coronavirus in humans with that in animals and found a 99% match with pangolins.

RegionsB and C span nt3,6259,150 and 9,26111,795, respectively. PubMed Central In the meantime, to ensure continued support, we are displaying the site without styles RegionsAC had similar phylogenetic relationships among the southern China bat viruses (Yunnan, Guangxi and Guizhou provinces), the Hong Kong viruses, northern Chinese viruses (Jilin, Shanxi, Hebei and Henan provinces, including Shaanxi), pangolin viruses and the SARS-CoV-2 lineage. PubMed Central The web application was developed by the Centre for Genomic Pathogen Surveillance. Lam, H. M., Ratmann, O. 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). performed codon usage analysis. D.L.R. This is evidence for numerous recombination events occurring in the evolutionary history of the sarbecoviruses22,33; specifying all past events in their correct temporal order34 is challenging and not shown here. CAS Martin, D. P., Murrell, B., Golden, M., Khoosal, A. Virus Evol. 21, 255265 (2004). The histogram allows for the identification of non-recombining regions (NRRs) by revealing regions with no breakpoints. Several of the recombinant sequences in these trees show that recombination events do occur across geographically divergent clades. DRAGEN COVID Lineage App This app aligns reads to a SARS-CoV-2 reference genome and reports coverage of targeted regions. Global epidemiology of bat coronaviruses. Evol. from the European Research Council under the European Unions Horizon 2020 research and innovation programme (grant agreement no. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. In December 2019, a cluster of pneumonia cases epidemiologically linked to an open-air live animal market in the city of Wuhan (Hubei Province), China1,2 led local health officials to issue an epidemiological alert to the Chinese Center for Disease Control and Prevention and the World Health Organizations (WHO) China Country Office. Using the most conservative approach to identification of a non-recombinant genomic region (NRR1), SARS-CoV-2 forms a sister lineage with RaTG13, with genetically related cousin lineages of coronavirus sampled in pangolins in Guangdong and Guangxi provinces (Fig. This statement informs us of the possibility that a virus has spilled over from a very rare and shy reptile-looking mammal . 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). # File containing the ID of the samples, the Sequence of the haplotype, the Continent, the country, the Region, the Data, the Lineage of Pangolin and Nextstrain clade, and the haplotype number # In this order # Could be obtained from the database RegionC showed no PI signals within it. At present, we analyzed the diversity of SARS-CoV-2 viral genomes in India to know the evolutionary patterns of viruses in the country through their pangolin lineage and GISAID-Clade. Microbes Infect. The Pango dynamic nomenclature is a popular system for classifying and naming genetically-distinct lineages of SARS-CoV-2, including variants of concern, and is based on the analysis of complete or near-complete virus genomes. 2 Lack of root-to-tip temporal signal in SARS-CoV-2. While it is possible that pangolins, or another hitherto undiscovered species, may have acted as an intermediate host facilitating transmission to humans, current evidence is consistent with the virus having evolved in bats resulting in bat sarbecoviruses that can replicate in the upper respiratory tract of both humans and pangolins25,32. Virological.org http://virological.org/t/ncov-2019-codon-usage-and-reservoir-not-snakes-v2/339 (2020). Nat. A deep dive into the genetics of the novel coronavirus shows it seems to have spent some time infecting both bats and pangolins before it jumped into humans, researchers said . The lineage B.1 has been the major basal and widespread lineage from the initial SARS-CoV-2 spread and it became the more prevalent lineage in Colombia ( 13 ), while the B.1.111 lineage, first detected in the USA from a sample collected on March 7, 2020 and subsequently in Colombia on March 13, 2020 is currently circulating and mainly represented The rate of genome generation is unprecedented, yet there is currently no coherent nor accepted scheme for naming the expanding .

Note that breakpoints can be shared between sequences if they are descendants of the same recombination events. performed recombination analysis for non-recombining alignment3, calibration of rate of evolution and phylogenetic reconstruction and dating. We extracted a total of 2189 full-length SARS-CoV-2 viral genomes from various states of India from the EpiCov repository of the GISAID initiative on 12 June 2020. Possible Bat Origin of Severe Acute Respiratory Syndrome Coronavirus 2 3). Lie, P., Chen, W. & Chen, J.-P. Duchene, S. et al. Suchard, M. A. et al. Microbiol. 2). A third approach attempted to minimize the number of regions removed while also minimizing signals of mosaicism and homoplasy. https://doi.org/10.1093/molbev/msaa163 (2020). Use of Genomics to Track Coronavirus Disease Outbreaks, New Zealand Proc. & Boni, M. F. Improved algorithmic complexity for the 3SEQ recombination detection algorithm. Zhou et al.2 concluded from the genetic proximity of SARS-CoV-2 to RaTG13 that a bat origin for the current COVID-19 outbreak is probable. However, on closer inspection, the relative divergences in the phylogenetic tree (Fig. & Minh, B. Q. IQ-TREE: a fast and effective stochastic algorithm for estimating maximum-likelihood phylogenies. 3). cov-lineages/pangolin - GitHub Rev. Posada, D., Crandall, K. A. Because 3SEQ is the most statistically powerful of the mosaic methods61, we used it to identify the best-supported breakpoint history for each potential child (recombinant) sequence in the dataset. J. Virol. J. Gen. Virol. However, inconsistency in the nomenclature limits uniformity in its epidemiological understanding. Pangolin-CoV is 91.02% and 90.55% identical to SARS-CoV-2 and BatCoV RaTG13, respectively, at the whole-genome level. Using the most conservative approach (NRR1), the divergence time estimate for SARS-CoV-2 and RaTG13 is 1969 (95% HPD: 19302000), while that between SARS-CoV and its most closely related bat sequence is 1962 (95% HPD: 19321988); see Fig. Download a free copy. Phylogenetic Assignment of Named Global Outbreak Lineages Eden, J.-S., Tanaka, M. M., Boni, M. F., Rawlinson, W. D. & White, P. A. Recombination within the pandemic norovirus GII.4 lineage. 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. Over relatively shallow timescales, such differences can primarily be explained by varying selective pressure, with mildly deleterious variants being eliminated more strongly by purifying selection over longer timescales44,45,46. Extended Data Fig. 2, bottom) show that SARS-CoV-2 is unlikely to have acquired the variable loop from an ancestor of Pangolin-2019 because these two sequences are approximately 1015% divergent throughout the entire Sprotein (excluding the N-terminal domain). Impact of SARS-CoV-2 Gamma lineage introduction and COVID-19 - Nature Accurate estimation of ages for deeper nodes would require adequate accommodation of time-dependent rate variation.

Exploring the temporal structure of heterochronous sequences using TempEst (formerly Path-O-Gen). Of the countries that have contributed SARS-CoV-2 data, 30% had genomes of this lineage. Using a third consensus-based approach for identifying recombinant regions in individual sequenceswith six different recombination detection methods in RDP5 (ref. 6, e14 (2017). 6, 8391 (2015). We named the length-sorted BFRs as: BFRA (ntpositions 13,29119,628, length=6,338nt), BFRB (ntpositions 3,6259,150, length=5,526nt), BFRC (ntpositions 9,26111,795, length=2,535nt), BFRD (ntpositions 27,70228,843, length=1,142nt) and six further regions (EJ). Novel Coronavirus (2019-nCoV) Situation Report 1, 21 January 2020 (World Health Organization, 2020). Did Pangolin Trafficking Cause the Coronavirus Pandemic? While there is evidence of positive selection in the sarbecovirus lineage leading to RaTG13/SARS-CoV-2 (ref. 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. 91, 10581062 (2010). Of importance for future spillover events is the appreciation that SARS-CoV-2 has emerged from the same horseshoe bat subgenus that harbours SARS-like coronaviruses. A counting renaissance: combining stochastic mapping and empirical Bayes to quickly detect amino acid sites under positive selection. Nat. Slider with three articles shown per slide. Developed by the Centre for Genomic Pathogen Surveillance. c, Maximum likelihood phylogenetic trees rooted on a 2007 virus sampled in Kenya (BtKy72; root truncated from images), shown for five BFRs of the sarbecovirus alignment.

China corresponds to Jilin, Shanxi, Hebei and Henan provinces, and the N. China clade also includes one sequence sampled in Hubei Province in 2004. Specifically, progenitors of the RaTG13/SARS-CoV-2 lineage appear to have recombined with the Hong Kong clade (with inferred breakpoints at 11.9 and 20.8kb) to form the CoVZXC21/CoVZC45-lineage. Emergence of SARS-CoV-2 through recombination and strong purifying selection. We infer time-measured evolutionary histories using a Bayesian phylogenetic approach while incorporating rate priors based on mean MERS-CoV and HCoV-OC43 rates and with standard deviations that allow for more uncertainty than the empirical estimates for both viruses (see Methods). 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.

The key to successful surveillance is knowing which viruses to look for and prioritizing those that can readily infect humans47. From this perspective, it may be useful to perform surveillance for more closely related viruses to SARS-CoV-2 along the gradient from Yunnan to Hubei. B.W.P. Nat Microbiol 5, 14081417 (2020). PDF How COVID-19 Variants Get Their Name - doh.wa.gov Background & objectives: Several phylogenetic classification systems have been devised to trace the viral lineages of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). PubMed PLoS Pathog. Open reading frames are shown above the breakpoint plot, with the variable-loop region indicated in the Sprotein. 94, e0012720 (2020). Pink, green and orange bars show BFRs, with regionA (nt 13,29119,628) showing two trimmed segments yielding regionA (nt13,29114,932, 15,40517,162, 18,00919,628). Another similarity between SARS-CoV and SARS-CoV-2 is their divergence time (4070years ago) from currently known extant bat virus lineages (Fig. Further information on research design is available in the Nature Research Reporting Summary linked to this article.

Because there is no single accepted method of inferring breakpoints and identifying clean subregions with high certainty, we implemented several approaches to identifying three classic statistical signals of recombination: mosaicism, phylogenetic incongruence and excessive homoplasy51. Subsequently a bat sarbecovirusRaTG13, sampled from a Rhinolophus affinis horseshoe bat in 2013 in Yunnan Provincewas reported that clusters with SARS-CoV-2 in almost all genomic regions with approximately 96% genome sequence identity2. B., Weaver, S. & Sergei, L. Evidence of significant natural selection in the evolution of SARS-CoV-2 in bats, not humans. In regionA, we removed subregion A1 (ntpositions 3,8724,716 within regionA) and subregion A4 (nt1,6422,113) because both showed PI signals with other subregions of regionA.
