The case for relationship of the flavobacteria and their relatives to the green sulfur bacteria.
Analysis of 16S rRNA sequences suggests, but does not convincingly demonstrate a specific relationship between the eubacterial phylum defined by the flavobacteria and their relatives and that defined by the green sulfur bacteria.  Consequently, we have sequenced the 23S rRNA from several representatives of the former group and one of the latter in order to bring more data to bear upon this point.  The 23S rRNA data alone strongly suggest a specific relationship between the two phyla, and, together with the 16S rRNA results, provides what we consider now to be a convincing case for this specific relationship.
