Genomic Characteristics of Desulfonema ishimotonii Tokyo 01^T Implying Horizontal Gene Transfer Among Phylogenetically Dispersed Filamentous Gliding Bacteria.

ABSTRACT: Desulfonema ishimotonii strain Tokyo 01^T is a filamentous sulfate-reducing bacterium isolated from a marine sediment. In this study, the genome of this strain was sequenced and analyzed with a focus on gene transfer from phylogenetically distant organisms. While the strain belongs to the class Deltaproteobacteria, hundreds of proteins encoded in the genome showed the highest sequence similarities to those of organisms outside of the class Deltaproteobacteria, suggesting that more than 20% of the genome is putatively of foreign origins. Many of these proteins had the highest sequence identities with proteins encoded in the genomes of filamentous bacteria, including giant sulfur oxidizers of the orders Thiotrichales, cyanobacteria of various genera, and
