Maximum likelihood phylogeny inferred under the GTR+F+I+G4 model from an open reading frame (ORF) 1AB alignment (17,592 bp, after trimming of sites with more than 10% of gaps), comprehending coronavirus sequences available on NCBI RefSeq and the novel Ptajacu-CoV. Different genera or Betacoronavirus clades are colour labelled and asterisks mark nodes inferred with low support values (SH-aLRT < 0.70). Branch lengths bigger than 0.7 have been trimmed and annotated to keep figure dimensions.
