Figure 3From: Hsp-90 and the biology of nematodesUnrooted phylogenetic tree showing relationship of hsp-90 sequences from fifteen different nematode species. The tree was generated using phyML [37] under the HKY substitution model. 1000 bootstrap replicates were performed and node labels represent percent bootstrap support. Branches A, B and C were shown to have significant evidence of positive selection. Scale bar shows substitutions per site.Back to article page
