FIGURE 13 in New dictyostelid cellular slime molds from South Africa

FIGURE 13. An 18S ribosomal RNA phylogeny including all new species of dictyostelids. The figure shows portions of a single tree expanded separately for the (A) Cavenderiaceae, (B) the Acytosteliaceae and (C) the Raperosteliaceae. The tree was derived by maximum likelihood analysis of ~1500 aligned positions of the SSU rDNA molecule using the program RAxML 8.2.10 with a GTR+gamma substitution model. The sequence alignment was staggered for two hypervariable regions so that only relationships within families were analyzed for these regions. New species described here are indicated in red and environmental (culture-independent) sequences in purple (Baldauf et al. 2018). Bootstrap values of 60-95% are shown on or adjacent to the relevant branches, and values of 95-100% are indicated by filled circles. The scale bar at the bottom indicates substitutions per site.
