From: Thiotrophic bacterial symbiont induces polyphenism in giant ciliate host Zoothamnium niveum
Bayesian tree inferred from the nucleotide sequences of the small subunit 18S rRNA gene of the monophyletic clade 2 of Zoothamnium and combined with colony drawings and life style. Support metrics are provided (BI/ML/MP). Scale bar corresponds to 1 substitution per 200 nt positions; numbers in parentheses are the NCBI accession numbers for each species. All colony drawings, including Z. alternans53, Z. pelagicum54, Z. plumula57, Z. ignavum51 and Z. niveum symbiotic43 and aposymbiotic Z. niveum (drawing from a colony grown in a flow-through chamber) show macrozooids in grey. Colony drawing of Z. plumula57 is under copyright and its use was granted by Magnolia Press www.mapress.com/j/zt. Colony drawings reproduction of Z. alternans53 was granted by the Instytut Biologii Doświadczalnej im. M. Nenckiego, and of Z. niveum43 by Elsevier. Colony drawing of Z. pelagicum54 is under copyright and its use was granted by CNRS Éditions (M. Laval; Zoothamnium pelagicum du Plessis. Cilié Péritriche planctonique: morphologie, croissance et comportement in Protistologica n°4 ©CNRS Éditions, 1968).
