Phylogenetic analysis of ribosomal RNA operons from uncultivated coastal marine bacterioplankton

Abstract

Analyses of small subunit ribosomal RNA genes (SSU rDNAs) have significantly influenced our understanding of the composition of aquatic microbial assemblages. Unfortunately, SSU rDNA sequences often do not have sufficient resolving power to differentiate closely related species. To address this general problem for uncultivated bacterioplankton taxa, we analysed and compared sequences of polymerase chain reaction (PCR)-generated and bacterial artificial chromosome (BAC)-derived clones that contained most of the SSU rDNAs, the internal transcribed spacer (ITS) and the large subunit ribosomal RNA gene (LSU rDNA). The phylogenetic representation in the rRNA operon PCR library was similar to that reported previously in coastal bacterioplankton SSU rDNA libraries. We observed good concordance between the phylogenetic relationships among coastal bacterioplankton inferred from SSU or LSU rDNA sequences. ITS sequences confirmed the close intragroup relationships among members of the SAR11, SAR116 and SAR86 clades that were predicted by SSU and LSU rDNA sequence analyses. We also found strong support for homologous recombination between the ITS regions of operons from the SAR11 clade.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
