Bayesian phylogenetic analyses of interhomolog recombination proteins. (a) SPO11 phylogeny based on an alignment of 284 amino acids. Parameter means: α = 2.16, pI = 0.019 and lnL = -9924.87. (b) MND1 phylogeny based on alignment of 205 amino acids. Parameter means: α = 1.87, pI = 0.024 and lnL = -5532.70. (c) HOP2 phylogeny based on an alignment of 192 amino acids. Parameter means: α = 3.23, pI = 0.022 and lnL = -6807.46. (d) RAD54/RAD54B phylogeny based on an alignment of 485 amino acids. Parameter means: α = 1.27, pI = 0.14 and lnL = -17500.27. (e) Phylogeny of RAD51-like family proteins based on an alignment 232 amino acids. Parameter means: α = 2.21, pI = 0.017 and lnL = -18082.74. For all analyses, the tree shown is a consensus of 951 best trees. Blue, red and black names indicate animals, fungi and choanoflagellates, respectively. Thickened branches refer to posterior probabilities from 0.95 to 1.0. Protein identifiers for D. pulex sequences (in bold) are in Additional File 2.
