Schematic representation of the mapping of conserved regions, functional motifs, and accessible regions to conserved regions on the six studied Influenza A viruses. The functional motifs, referred to as(M), are highlighted in red and numbered in each segment (m1, m2, etc), the accessible regions are highlighted in grey, and the highly conserved regions are framed in orange. The location, length and conservation percentage of each segment are shown in additional file 7. The location length and sequence of each functional motif is shown in table 3. The location and length of each accessible region is shown in additional file 9.
