Loss of the flagellum happened only once in the fungal lineage: phylogenetic structure of Kingdom Fungi inferred from RNA polymerase II subunit genes

Table 3 Comparison between 18S rRNA and RPB gene phylogenies in the topology and statistical support for the major clades.

Major clade	18S rDNA	RPB1+RPB2
Monophyletic Ascomycota	100%, 75% ^a	100%, 99%
Monophyletic Basidiomycota	100%, 89%	100%, 100%
Monophyletic Dikaryomycota	100%, 89%	100%, 100%
Monophyletic Zygomycota	No (polyphyletic)	100%, 78%
Clade of Asco-, Basidio- and Zygomycota	No ^b	100%, 84%
Monophyletic Chytridiomycota	No (polyphyletic)	No (paraphyletic)
Monophyletic kingdom Fungi	72%, 71%	100%, 91%
Microsporidia sister to Fungi	No^c	100%, 99%

a. The numbers are the values of Bayesian posterior probability and parsimony bootstrap support respectively.
b. Zygomycota did not form a clade with Ascomycota and Basidiomycota in the 18S rDNA phylogeny (Figure 2A).
c. Microsporidia is not included in the phylogenetic analyses based on 18S rDNA (Figure 2A) due to highly divergence of the sequences and difficulty in the alignment.
