Fig. 3From: Identification of combinatorial host-specific signatures with a potential to affect host adaptation in influenza A H1N1 and H3N2 subtypesPhylogeny of PB2 H3N2 protein of avian hosts annotated with top 5 avian rules form the PB2 H3N2 model. Each sequences is represented by its GeneBank accession. The violet nodes mark the sequences that supports rule 1,2,3,4 and 5, which are 91.4Â % of the total sequences. Similarly the DarkViolet nodes mark the sequences that support rule 1, 2, 3 and 4 but lacks support for rule 5, which are 2.2Â % of the total sequences. The nodes with a LightBlue background are the new, unseen sequences. The unmarked nodes do not support the top 5 rules, and were either supporting rules other than the top 5 or were not classified by the modelsBack to article page
