Horizontal gene transfer is one of the main mechanisms contributing to microbial genome diversification. To clarify the overall picture of interspecific gene flow among prokaryotes, we developed a new method for detecting horizontally transferred genes and their possible donors by Bayesian inference with training models for nucleotide composition.

Corynebacterium efficiens is the closest relative of Corynebacterium glutamicum, a species widely used for the industrial production of amino acids. C. efficiens but not C. glutamicum can grow above 40 degrees C. We sequenced the complete C. efficiens genome to investigate the basis of its thermostability by comparing its genome with that of C. glutamicum.(More)
Nori, a marine red alga, is one of the most profitable mariculture crops in the world. However, the biological properties of this macroalga are poorly understood at the molecular level. In this study, we determined the draft genome sequence of susabi-nori (Pyropia yezoensis) using next-generation sequencing platforms. For sequencing, thalli of P. yezoensis(More)
Corynebacterium species are members of gram-positive bacteria closely related to Mycobacterium species, both of which are classified into the same taxonomic order Actinomycetales. Recently, three corynebacteria, Corynebacterium efficiens, Corynebacterium glutamicum, and Corynebacterium diphtheriae have been sequenced independently. We found that the order(More)
The accelerated progress of ultra high-throughput DNA sequencing technologies has facilitated the process of identifying microsatellites in the genomes, attenuating laborious experimental procedures involved in traditional approaches. We applied a massively parallel pyrosequencing technique to the development of tetra- and pentanucleotide microsatellite(More)
Corynebacterium glutamicum, which is the closest relative of Corynebacterium efficiens, is widely used for the large scale production of many kinds of amino acids, particularly glutamic acid and lysine, by fermentation. Corynebacterium diphtheriae, which is well known as a human pathogen, is also closely related to these two species of Corynebacteria, but(More)
We report the complete genome sequences of two Edwardsiella tarda-lytic bacteriophages isolated from flounder kidney (KF-1) and seawater (IW-1). These newly sequenced phage genomes provide a novel resource for future studies on phage-host interaction mechanisms and various applications of the phages for control of edwardsiellosis in aquaculture. E(More)
We present the genome sequence of a novel Edwardsiella tarda-lytic bacteriophage, MSW-3, which specifically infects atypical E. tarda strains. The morphological and genomic features of MSW-3 suggest that this phage is a new member of the dwarf myo-viruses, which have been much less studied than other groups of myoviruses. T. 2013. Complete genome sequence(More)
Edwardsiella tarda is an enterobacterium which causes edwardsiellosis, a fatal disease of cultured fishes such as red sea bream, eel, and flounder. Preventing the occurrence of E. tarda infection has thus been an important issue in aquaculture. E. tarda has been isolated from other animals and from many environments; however, the relationship between the(More)
We present the complete genome sequence for a novel Edwardsiella ictaluri-specific bacteriophage, PEi21, isolated from river water in Japan. An initial comparative genome analysis revealed that the phage was closely related to the previously reported Edwardsiella tarda phage MSW-3 isolated from a red sea bream farm in Japan.
