Figure 1

Maximum-likelihood phylogeny of the CK/CH/SCMY/160315 strain (green star) and 82 IBV reference strains based on the complete nucleotide sequence of the S1 gene. Four other strains are highlighted with red circles for comparison. The trees were constructed using 1,000 bootstrap replicates with the MEGA 7.0 software. The 82 reference strains include 78 reference strains classified as GI-GVII genotypes and 4 strains (highlighted using a red circle) which were used for whole genome sequence comparison, phylogenetic analysis and the recombination analysis.
