Orthologs of Escherichia coli ygjD and yeaZ genes are highly conserved in various organisms. The genome of the radioresistant bacterium Deinococcus radiodurans possesses single orthologs of ygjD (DR_0382) and yeaZ (DR_0756). Complete loss of either one or both genes did not result in any significant changes in cell growth efficiency, indicating that both(More)
Here, we have developed an extremely efficient in vivo Tn5-based mutagenesis procedure to construct a Deinococcus radiodurans insertion mutant library subsequently screened for sensitivity to genotoxic agents such as γ and UV radiations or mitomycin C. The genes inactivated in radiosensitive mutants belong to various functional categories, including DNA(More)
Calcium-dependent Paenibacillus sp. strain TCA20 was isolated from a water sample of a hot spring containing a high concentration of calcium ions. Here, we report the draft genome sequence of this bacterium, which may be the basis for the research of calcium ion homeostasis.
The potassium-dependent alkaliphilic Bacillus sp. strain TS-2 was isolated from the mashed extract of a jumping spider, and its draft genome sequence was obtained. Comparative genomic analysis with a previously sequenced sodium-dependent alkaliphilic Bacillus species may reveal potassium-dependent alkaline adaptation mechanisms.
Deinococcus grandis is a radioresistant bacterium isolated from freshwater fish in Japan. Here we reported the draft genome sequence of D. grandis (4.1 Mb), which will be useful for elucidating the common principles of radioresistance in Deinococcus species through the comparative analysis of genomic sequences.
Methylobacterium sp. ME121 was isolated from soil as a mixed single colony with Kaistia sp. 32K, and its growth was enhanced by coculture. Here, we report the draft genome sequence of Methylobacterium sp. ME121, which may contribute to the study of the molecular mechanisms underlying this phenomenon.
Alkaliphilic Microbacterium sp. strain TS-1, newly isolated from the jumping spider, showed Na(+)-independent growth and motility. Here, we report the draft genome sequence of this bacterium, which may provide beneficial information for Na(+)-independent alkaline adaptation mechanisms.
