FIG. 5.

Maximum-likelihood tree of the HSP70 alignment (the 492 positions marked in Fig. 1). The QP method was used with a gamma-distributed model of site-to-site rate variation using eight rate categories. The gamma distribution parameter α estimated from the data set was 0.71 ± 0.04, and the log-likelihood of the tree was −19,510.8. Numbers above nodes are QP reliability values. The scale bar represents 0.1 amino acid substitution per site. For other details, see the legend to Fig. 3.
