Diagram showing the position of the coding sequences (CDS, grey arrows) and the mature peptides (black arrows) in the IBV genome. The numbers indicate the nucleotide position. The black dotted lines are used to magnify the annotations of the smaller peptides to increase clarity. Nsp, non‐structural protein. *, nsp 11. This genome arrangement is based on the nucleotide sequence of the Australian IBV vaccine strain VicS.
