Evolution of the Order Urostylida (Protozoa, Ciliophora): New Hypotheses Based on Multi-Gene Information and Identification of Localized Incongruence
Figure 2
Phylogeny of the class Spirotrichea inferred by ML of SSU rRNA gene sequences (A), and two systems (B, C).
A. Urostylids are labeled in colours. Species newly sequenced in the present study is shown in bold type. BP for ML tree and PP for BI tree are given near nodes, respectively. Asterisks show different node topologies between BI and ML trees. Fully supported (100%/1.00) branches are marked with solid circles. The scale bar corresponds to 5 substitutions per 100 nucleotide positions; black dot marks the genus Hemigastrostyla which is a non-urostylid. B. System of Lynn [1] containing only sequenced urostylid genera, with several highlighted genera not included by Lynn [1]. C. System of Berger [9] containing only sequenced urostylid genera.
