Fig. 2From: HSP70 from the Antarctic sea urchin Sterechinus neumayeri: molecular characterization and expression in response to heat stressPhylogenetic relationships among Hsp70 family members. The tree was constructed by Neighbour-Joining method. Numbers at each branch indicate the percentage of bootstrap values after 1000 replications. Scale bar represent the amino acid substitutions per site for a unit branch lengthBack to article page
