Complete genome sequence of the extremely acidophilic methanotroph isolate V4, Methylacidiphilum infernorum, a representative of the bacterial phylum Verrucomicrobia (2008)

Hou, Shaobin, Makarova, Kira S, Saw, Jimmy HW, Senin, Pavel, Ly, Benjamin V, Zhou, Zhemin, ...

Abstract Background The phylum Verrucomicrobia is a widespread but poorly characterized bacterial clade. Although cultivation-independent approaches detect representatives of this phylum in a wide...

Comparative genomics of Thermus thermophilusand Deinococcus radiodurans: divergent routes of adaptation to thermophily and radiation resistance (2005)

Omelchenko, Marina V, Wolf, Yuri I, Gaidamakova, Elena K, Matrosova, Vera Y, Vasilenko, Alexander, Zhai, Min, ...

Abstract Background Thermus thermophilus and Deinococcus radiodurans belong to a distinct bacterial clade but have remarkably different phenotypes. T. thermophilus is a thermophile, which is...

Evolution of mosaic operons by horizontal gene transfer and gene displacement in situ (2003)

Omelchenko, Marina V, Makarova, Kira S, Wolf, Yuri I, Rogozin, Igor B, Koonin, Eugene V

Abstract Background Shuffling and disruption of operons and horizontal gene transfer are major contributions to the new, dynamic view of prokaryotic evolution. Under the 'selfish operon' hypothesis,...

Genome Sequence and Comparative Analysis of the Solvent-Producing Bacterium Clostridium acetobutylicum

Nölling, Jörk, Breton, Gary, Omelchenko, Marina V., Makarova, Kira S., Zeng, Qiandong, Gibson, Rene, ...

The genome sequence of the solvent-producing bacterium Clostridium acetobutylicum ATCC 824 has been determined by the shotgun approach. The genome consists of a 3.94-Mb chromosome and a 192-kb...

Transcriptome dynamics of Deinococcus radiodurans recovering from ionizing radiation

Liu, Yongqing, Zhou, Jizhong, Omelchenko, Marina V., Beliaev, Alex S., Venkateswaran, Amudhan, Stair, Julia, ...

Deinococcus radiodurans R1 (DEIRA) is a bacterium best known for its extreme resistance to the lethal effects of ionizing radiation, but the molecular mechanisms underlying this phenotype remain...

Evolution of mosaic operons by horizontal gene transfer and gene displacement in situ

Omelchenko, Marina V, Makarova, Kira S, Wolf, Yuri I, Rogozin, Igor B, Koonin, Eugene V

Comparative genomics and phylogenetic analysis have been used to examine horizontal transfer of entire operons versus displacement of individual genes within operons by horizontally acquired...

Genome-Wide Molecular Clock and Horizontal Gene Transfer in Bacterial Evolution

Novichkov, Pavel S., Omelchenko, Marina V., Gelfand, Mikhail S., Mironov, Andrei A., Wolf, Yuri I., Koonin, Eugene V.

We describe a simple theoretical framework for identifying orthologous sets of genes that deviate from a clock-like model of evolution. The approach used is based on comparing the evolutionary...

Genome sequence of the deep-sea γ-proteobacterium Idiomarina loihiensis reveals amino acid fermentation as a source of carbon and energy

Hou, Shaobin, Saw, Jimmy H., Lee, Kit Shan, Freitas, Tracey A., Belisle, Claude, Kawarabayasi, Yutaka, ...

We report the complete genome sequence of the deep-sea γ-proteobacterium, Idiomarina loihiensis, isolated recently from a hydrothermal vent at 1,300-m depth on the Lōihi submarine volcano, Hawaii....

Transcriptome Analysis Applied to Survival of Shewanella oneidensis MR-1 Exposed to Ionizing Radiation

Qiu, Xiaoyun, Daly, Michael J., Vasilenko, Alexander, Omelchenko, Marina V., Gaidamakova, Elena K., Wu, Liyou, ...

The ionizing radiation (IR) dose that yields 20% survival (D20) of Shewanella oneidensis MR-1 is lower by factors of 20 and 200 than those for Escherichia coli and Deinococcus radiodurans,...
