Recombination events in DENV-1 strains. Schematic representation indicates the recombination events in DENV-1 strains analyzed by RDP3 package with P-value < 0.05. Continues lines indicate no recombination possibility. Analysis was performed on all sequences included in the phylogenetic tree in Figure 3. The following strains did not show any recombination events and are not shown in the figure; KJ189366-Peurto Rico-2010, KJ189304-Colombia-2005, JN054256-SriLanka-2009, KF955446-Vietnam-2008, JX669473-Brazil-2001, JQ915076-French Polynesia:Tahiti-2009, FJ850114-Nicaragua-2005, FJ810415-Venezuela-2005, JN697058-Malaysia-2005, GQ398255-Singapore-2008 and AB074761-Japan-2001.
