Fig. 2 — Phylogenetic tree of Spo11 proteins inferred from maximum likelihood analysis. Archaeal topoisomerase VIA protein sequences (underlined) were used as an out-group.

Among-site substitution rate heterogeneity was corrected using two gamma-distributed substitution rate categories and LG substitution model for amino acid substitutions. Diatom sequences are indicated in bold
