Harvest and phylogenetic network analysis of SARS virus genomes (CoV-1 and CoV-2)

(2020), <i>PNAS</i>, doi: 10.1073/pnas.2004999117 <br><i></i>The 7z-archive [7z.org/Wikipedia] includes all used data (non-curated gene bank harvest, curated alignment) and analysis files in standard phylogenetic data formats (FASTA, NEXUS, NEWICK, Splits-NEXUS). For labelling conventions and archive content see ReadMe.txt.<br>New in Version 2: Fully annotated genotype spread sheet, <i>CoV2Genotyping</i> (XLSX) of the CoV-2 subsample included in our original harvest tabulating particular and general mutations patterns. The archive has been updated.<br><br><b>Figures</b><i>MLTreeStrictGrCons.png—</i>Maximum likelihood tree based on strict group consensus sequences and branch support established via non-parametric bootstrapping<i>NNetCPlusRecomb.png—</i>Uncorrected <i>p-</i>distance (Hamming) based planar phylogenetic network based on the (strict) group consensus<br>data. Coloured lines refer to shared sequence patterns as visible from the alignment (likely recombination events)<i>NNetPlusSupport.png—</i>Uncorrected <i>p</i>-distance (Hamming) based planar phylogenetic networks based on the non-consensed (original) data (in total, 291 near-complete virus genomes) used to define major groups for consensing approach. Bottom-right, bootstrap consensus network for the same data.<i>MutationPatterns1, ...2—</i>Visualisation of mutation patterns that are either the consequence of homoplasy, i.e. convergent mutation from C to U in independent CoV-2 sublineages, or recombination.
