Figure 4From: Linear normalised hash function for clustering gene sequences and identifying reference sequences from multiple sequence alignmentsThe linear mapping clustering for the 109 EV71 VP1 sequences shown on the first and second PCA coordinates. Eleven clusters corresponding to the genogroups/subgenogroups are presented. The legend indicates EV71 VP1 genogroups/subgenogroups, years of isolation for sequences viruses or their deposition to GenBank, and country of origin. Relevant cluster centroids are highlighted in red. Isolate AF 119795 (&), belonging to C/B genogroups, is a result of intergenotypic recombination [41].
