Figure 2From: Higher transactivation activity associated with LTR and Tat elements from HIV-1 BF intersubtype recombinant variantsPhylogenetic analysis of 24 LTR sequences from Argentinean samples. A neighbour-joining phylogenetic tree was built and maximum parsimony bootstrap values were calculated. The genetic distance corresponding to the length of the branches is shown by the bottom line. Reference samples are those recommended by the Los Alamos Database. ▲ and ●: Unknown samples.Back to article page
