ABSTRACT “ Candidatus Hamiltonella defensa” is a facultative endosymbiont of the whitefly Bemisia tabaci . Herein, we report the first draft genome sequence of “ Candidatus Hamiltonella defensa” from the invasive Mediterranean cryptic species of the B. tabaci complex. The 1.84-Mbp genome sequence comprises 404 contigs and contains 1,806 predicted protein-coding genes.

ABSTRACT We report the genome sequence of actinobacterial strain IMCC13023, isolated from arctic fjord seawater. Phylogenetic analysis of 16S rRNA gene showed that the strain is related to “ Candidatus Aquiluna rubra.” The genome information suggests that strain IMCC13023 is a photoheterotroph carrying actinorhodopsin, with the smallest genome ever reported for a free-living member of the Actinobacteria .

ABSTRACT Ammonia-oxidizing archaea (AOA) play important roles in nitrogen and carbon cycling in marine and terrestrial ecosystems. Here, we present the draft genome sequence for the ammonia-oxidizing archaeon “ Candidatus Nitrosopumilus salaria” BD31, which was enriched in culture from sediments of the San Francisco Bay estuary. The genome sequences revealed many similarities to the genome of Nitrosopumilus maritimus .

ABSTRACT Here, we present the draft genome sequence of “ Candidatus Nitrosoarchaeum limnia” BG20, an ammonia-oxidizing archaeon enriched in culture from low-salinity sediments of the San Francisco Bay estuary. The genome sequence revealed many similarities to the previously sequenced genome of “ Ca. Nitrosoarchaeum limnia” SFB1 (enriched from a nearby site in San Francisco Bay) and is representative of a clade of ammonia-oxidizing archaea (AOA) found in low-salinity habitats worldwide.

ABSTRACT We present the genome sequence of “ Candidatus Mycoplasma haemominutum” strain Birmingham 1, a low-pathogenicity feline hemoplasma strain.
