Fig. 5

Phylogenetic incongruity among rotavirus segments confirming genomic reassortment. Diagram outlines G1P[8] VP7-VP4 segments and the DS-1-like backbone segments in four Vietnamese G1P[8] rotaviruses. a Tanglegram showing corresponding VP7 and VP4 segments of G1P[8] and G2P[4] genotypes. b Tanglegram showing phylogenetic incongruity between the VP7 and VP6 segments of the G1P[8] and G2P[4] genotype for four reassortant rotaviruses from Vietnam. Sequences from nonreassortant Vietnamese rotaviruses are indicated by connection with black lines. Sequences from reassortant Vietnamese viruses are indicated by connection with red lines. Segments between which no reassortment is detected (i.e. VP7-VP4) are depicted with reassortant viruses connected by red dashed lines. Asterisks indicate ≥85% bootstrap support at internal nodes of interest
