Abstract

‘Candidatus Chloroploca asiatica’ B7–9 and ‘Candidatus Viridilinea mediisalina’ Kir15-3F are mesophilic filamentous anoxygenic phototrophic bacteria from alkaline aquatic environments. Both bacteria became available in the last few years and only in stable enrichment culture. In this study, we report the draft genomic sequences of ‘Ca. Chloroploca asiatica’ B7–9 and ‘Ca. Viridilinea mediisalina’ Kir15-3F, which were assembled from metagenomes of their cultures with a fold coverage 86.3× and 163.8×, respectively. The B7–9 (5.8 Mb) and the Kir15-3F (5.6 Mb) draft genome harbors 4818 and 4595 predicted protein-coding genes, respectively. In this article, we analyzed the phylogeny of representatives of the Chloroflexineae suborder in view of the appearance of new genomic data. These data were used for the revision of earlier published group-specific conserved signature indels and for searching for novel signatures for taxons in the Chloroflexineae suborder.
