Disease relevance of rrna

• Lipid A analyses confirm not only the present taxa of the purple nonsulfur bacteria (formerly Rhodospirillaceae), but also phylogenetical relatedness of distinct phototrophic to distinct non-phototrophic bacteria, as was suggested by cataloguing 16S rRNA [1].
• Comparative analyses of ribosomal 16S rRNA gene and internally transcribed spacer region sequences indicated that B. denitrificans is a member of the alpha-subdivision of Proteobacteria [2].
• All strains showed positive signals for tfdAalpha, and its phylogenetic tree was congruent with that of 16S rRNA genes in alpha-Proteobacteria, indicating evolution of tfdAalpha without horizontal gene transfer [3].
• The phylogeny of bacteria belonging to the genus Nitrobacter was investigated by sequencing the whole 16S rRNA gene [4].
• Phylogeny of the phototrophic rhizobium strain BTAi1 by polymerase chain reaction-based sequencing of a 16S rRNA gene segment [5].

High impact information on rrna

• The cadA genes were phylogenetically separated between 2,4-D-degrading and nondegrading strains, and the cadA genes of 2,4-D degrading strains were further separated between Bradyrhizobium sp. and Sphingomonas sp., indicating the incongruency of cadA with 16S rRNA genes [3].
• Representatives of these four major genotypes were tentatively identified as R. palustris based on phylogentic analyses of 16S rRNA gene sequences [6].
• 16S rRNA sequences of Bartonella bacilliformis and cat scratch disease bacillus reveal phylogenetic relationships with the alpha-2 subgroup of the class Proteobacteria [7].
• Based on 16S rRNA gene sequences, the 14 strains could be grouped into three distinct clusters (A, B, and C), and this clustering was congruent with that based on gene sequences of form II ribulose-1,5-bisphosphate carboxylase/oxygenase (RubisCO) [8].
• The relatedness of these species to the glucosamine-containing species of the genus Rhizobium and to Agrobacterium tumefaciens is rather distant as documented by 16S rRNA studies [9].

Analytical, diagnostic and therapeutic context of rrna

• A 260-bp segment of the DNA that encodes 16S rRNA, corresponding to positions 44 to 337 in the Escherichia coli sequence, was amplified by the polymerase chain reaction and sequenced from each of 13 bacteria (rhizobia and purple phototrophs) in the alpha subdivision of the class Proteobacteria [5].
• 16S rRNA gene clone sequence analysis revealed that the bacteria affiliated with Alphaproteobacteria, followed by Betaproteobacteria, were numerically important microbial groups in three tanks [10].
• The bacterial community structure, in situ spatial distributions and activities of nitrifying and denitrifying bacteria in biofilms treating industrial wastewater were investigated by combination of the 16S rRNA gene clone analysis, fluorescence in situ hybridization (FISH) and microelectrodes [10].
