Sequencing of bacterial and archaeal genomes has revolutionized our understanding of the many roles played by microorganisms. There are now nearly 1,000 completed bacterial and archaeal genomes available, most of which were chosen for sequencing on the basis of their physiology. As a result, the perspective provided by the currently available genomes is(More)
Pseudomonas fluorescens are common soil bacteria that can improve plant health through nutrient cycling, pathogen antagonism and induction of plant defenses. The genome sequences of strains SBW25 and Pf0-1 were determined and compared to each other and with P. fluorescens Pf-5. A functional genomic in vivo expression technology (IVET) screen provided(More)
Metagenomics is a rapidly emerging field of research for studying microbial communities. To evaluate methods presently used to process metagenomic sequences, we constructed three simulated data sets of varying complexity by combining sequencing reads randomly selected from 113 isolate genomes. These data sets were designed to model real metagenomes in terms(More)
Thermobifida fusca is a moderately thermophilic soil bacterium that belongs to Actinobacteria. It is a major degrader of plant cell walls and has been used as a model organism for the study of secreted, thermostable cellulases. The complete genome sequence showed that T. fusca has a single circular chromosome of 3,642,249 bp predicted to encode 3,117(More)
Bacteria of the genus Deinococcus are extremely resistant to ionizing radiation (IR), ultraviolet light (UV) and desiccation. The mesophile Deinococcus radiodurans was the first member of this group whose genome was completely sequenced. Analysis of the genome sequence of D. radiodurans, however, failed to identify unique DNA repair systems. To further(More)
As random shotgun metagenomic projects proliferate and become the dominant source of publicly available sequence data, procedures for the best practices in their execution and analysis become increasingly important. Based on our experience at the Joint Genome Institute, we describe the chain of decisions accompanying a metagenomic project from the viewpoint(More)
We report the complete genome of Thermofilum pendens, a deeply branching, hyperthermophilic member of the order Thermoproteales in the archaeal kingdom Crenarchaeota. T. pendens is a sulfur-dependent, anaerobic heterotroph isolated from a solfatara in Iceland. It is an extracellular commensal, requiring an extract of Thermoproteus tenax for growth, and the(More)
The relationship between the hyperthermophiles Ignicoccus hospitalis and Nanoarchaeum equitans is the only known example of a specific association between two species of Archaea. Little is known about the mechanisms that enable this relationship. We sequenced the complete genome of I. hospitalis and found it to be the smallest among independent, free-living(More)
The gene encoding alkaline phosphatase (AP) from the psychrophilic strain TAB5 was cloned, and its nucleotide sequence was determined. A single open reading frame consisting of 1125 base pairs which encodes a polypeptide consisting of signal peptide of 22 amino acids and a mature protein of 353 amino acids was identified. The deduced protein sequence of AP(More)
The genomes of three representatives of the family Methylophilaceae, Methylotenera mobilis JLW8, Methylotenera versatilis 301, and Methylovorus glucosetrophus SIP3-4, all isolated from a single study site, Lake Washington in Seattle, WA, were completely sequenced. These were compared to each other and to the previously published genomes of Methylobacillus(More)
