From: A full-length S1 gene sequencing of a novel emerged GI-19 and GI-23 lineages of Infectious bronchitis virus currently circulating in chicken flocks in upper Egypt reveals marked genetic diversity and recombination events

Fig. 3

A ccollective phylogenetic tree was constructed using the nucleotide sequence alignments of Full-length S1 gene sequencing (1610 Nucleotide) in comparison to other reference strains including Egyptian strains. The phylogenetic analysis of the S1 gene revealed that 5 ACoV isolates (labelled with blue colour and black triangle) were located in various genotypes as follows: (three isolates clustered as GI-23, two isolates clustered as GI-19). The tree was constructed by the Maximum likelihood method with 1,000 bootstrap replicates, using MEGA 7.0 software
