BACKGROUND The number of available genome sequences is increasing, and easy-to-use software that enables efficient comparative analysis is needed. RESULTS We developed GenomeMatcher, a stand-alone software package for Mac OS X. GenomeMatcher executes BLAST and MUMmer, and the detected similarities are displayed in two-dimensional and parallel views with(More)
Rhizobia are nitrogen-fixing soil bacteria that establish endosymbiosis with some leguminous plants. The completion of several rhizobial genome sequences provides opportunities for genome-wide functional studies of the physiological roles of many rhizobial genes. In order to carry out genome-wide phenotypic screenings, we have constructed a large mutant(More)
Ralstonia pickettii strain DTP0602 utilizes 2,4,6-trichlorophenol as its sole carbon and energy source. Here, we report the complete genome sequence of strain DTP0602, which comprises three chromosomes and no plasmids. We also found that the two had gene clusters responsible for the degradation of 2,4,6-trichlorophenol are located on the 2.9-Mb chromosome 2.
The deep sequencing of 16S rRNA genes amplified by universal primers has revolutionized our understanding of microbial communities by allowing the characterization of the diversity of the uncultured majority. However, some universal primers also amplify eukaryotic rRNA genes, leading to a decrease in the efficiency of sequencing of prokaryotic 16S rRNA(More)
Haloalkane dehalogenases are key enzymes for the degradation of halogenated aliphatic pollutants. Two rhizobial strains, Mesorhizobium loti MAFF303099 and Bradyrhizobium japonicum USDA110, have open reading frames (ORFs), mlr5434 and blr1087, respectively, that encode putative haloalkane dehalogenase homologues. The crude extracts of Escherichia coli(More)
γ-Hexachlorocyclohexane (γ-HCH) is a man-made chlorinated insecticide that has caused serious environmental problems. Here, we report the complete genome sequence of the γ-HCH-degrading bacterium Sphingomonas sp. strain MM-1, which consists of one chromosome and five plasmids. All the specific lin genes that are almost identical to those of Sphingobium(More)
Extracellular alginate lyase (alyA) has an important role in the use of alginate in the marine bacterial strain Pseudoalteromonas atlantica AR06. Green fluorescent protein (GFP) is a convenient, useful tool for visualization of gene expression, and here we introduced the gfp gene at the end of alyA by homologous recombination in AR06. The gfp gene was(More)
Sphingomonas paucimobilis UT26 utilizes gamma-hexachlorocyclohexane (gamma-HCH) as a sole source of carbon and energy. In our previous study, we cloned and characterized genes that are involved in the conversion of gamma-HCH to maleylacetate (MA) via chlorohydroquinone (CHQ) in UT26. In this study, we identified and characterized an MA reductase gene,(More)
Soil microbial communities have great potential for bioremediation of recalcitrant aromatic compounds. However, it is unclear which taxa and genes in the communities, and how they contribute to the bioremediation in the polluted soils. To get clues about this fundamental question here, time-course (up to 24 weeks) metagenomic analysis of microbial community(More)
The replicative DNA polymerase Polδ consists of a catalytic subunit POLD1/p125 and three regulatory subunits POLD2/p50, POLD3/p66 and POLD4/p12. The ortholog of POLD3 in Saccharomyces cerevisiae, Pol32, is required for a significant proportion of spontaneous and UV-induced mutagenesis through its additional role in translesion synthesis (TLS) as a subunit(More)
