Phylogenetic analysis of the complete S1 genes of newly identified IBV in 2019. Phylogenetic analysis based on the deducted amino acid sequences of complete S1 gene of HeN‐1/China/2019, HeN‐2/China/2019, HeN‐101/China/2019 and other IBV isolates available from GenBank database. Phylogenetic tree was constructed by MEGA 7.0 software using the neighbour‐joining method with 1,000 bootstrap replicates. The seven different IBV genotype, with 35 distinct lineage IBV strains were illustrated by the colour scale with iTOL software. Meanwhile, the available IBV vaccine strains in China were indicated by blue star, and the three IBV isolates in this study were indicated by red star [Colour figure can be viewed at wileyonlinelibrary.com]
