Bayesian phylogeny of the SSU rDNA sequences obtained from the collodarians.

<p>Four novel collodarian sequences and two environmental sequences (<3 µm) are shown in bold and light gray text, respectively. Family names are shown to the right of the black bars. Numbers on nodes indicates posterior probabilities of the Bayesian method and bootstrap values of the ML analysis. Scale bar at lower left shows 0.1 substitutions per site for the Bayesian analyses.
