FIGURE 1. Molecular phylogeny of Chloroidium based on SSU and ITS rDNA sequence comparisons. The phylogenetic trees shown were inferred using the maximum likelihood method based on the data sets (2643 aligned positions of 58 taxa) using PAUP 4.0b10. For the analyses the best model was calculated by Modeltest 3.7. The setting of the best model was given as follows: GTR+I+G (base frequencies: A 0.2263, C 0.2597, G 0.2814, T 0.2326; rate matrix A-C 3.0220, A-G 3.2461, A-U 1.8828, C-G 1.0985, C-U 7.0041, G-U 1.0000) with the proportion of invariable sites (I = 0.7069) and gamma shape parameter (G = 0.6406). The branches in bold are highly supported in all analyses (Bayesian values> 0.95 calculated with PHASE and MrBayes; bootstrap values> 70% calculated with PAUP using maximum likelihood, neighbor-joining, maximum parsimony and RAxML using maximum likelihood). The taxa originally described as Parachloroidium were indicated by an asterisk. The ITS-2 haplotype designations as well as the geographical origins and habitats are given color-coded after the strain designations.
