Figure 1.

Phylogenetic tree of the 17 human Hsp70 proteins encoded in the genes studied in this work. The seven distinct evolutionary groups supported by bootstrap values (1000 samples) equal or greater than 85% are indicated by brackets to the right. Alignments were obtained with Clustal W [42] and the evolutionary tree was obtained using the neighbor-joining algorithm [38] with the distance transformation method of Kimura [39], as implemented in Clustal W. A similar tree (not shown) was obtained using the maximum likelihood approach implemented in the program PHYML [40].
