Genome Announcements

ABSTRACT We report here the draft genome sequence of “ Candidatus Liberibacter asiaticus” strain HHCA, collected from a lemon tree in California. The HHCA strain has a genome size of 1,150,620 bp, 36.5% G+C content, 1,119 predicted open reading frames, and 51 RNA genes.

ABSTRACT Phytoplasmas are unculturable plant-pathogenic bacteria causing devastating damage to agricultural production worldwide. Here, we report the draft genome sequence of “ Candidatus Phytoplasma asteris” strain OY-V. Most of the known virulence factors and host-interacting proteins were conserved in OY-V. This genome furthers our understanding of genetic diversity and pathogenicity of phytoplasmas.

ABSTRACT The endosymbiont of Acanthamoeba strain UWC8 is an obligate amoeba endosymbiont belonging to the family of “ Candidatus Midichloriaceae” in Rickettsiales. We report here the complete genome sequence of this bacterium, which should catalyze future studies of amoeba-symbiont interactions.

ABSTRACT Here, we present the draft genome of the endosymbiont “ Candidatus Ruthia magnifica” UCD-CM, a member of the phylum Proteobacteria , found from the gills of a deep-sea giant clam, Calyptogena magnifica . The assembly consists of 1,160,249 bp contained in 18 contigs.

ABSTRACT “ Candidatus Arthromitus” sp. strain SFB-mouse-NL (SFB, segmented filamentous bacteria) is a commensal bacterium necessary for inducing the postnatal maturation of homeostatic innate and adaptive immune responses in the mouse gut. Here, we report the genome sequence of this bacterium, which sets it apart from earlier sequenced mouse SFB isolates.

ABSTRACT Members of the Cronobacter genus are associated with serious infections in neonates. This is the first report of the draft genome sequence for the newly proposed species Cronobacter colletis .

ABSTRACT The draft genome sequence of “ Candidatus Liberibacter asiaticus” strain A4, isolated from a mandarin citrus in Guangdong, People's Republic of China, is reported. The A4 strain has a genome size of 1,208,625 bp, G+C content of 36.4%, 1,107 predicted open reading frames, and 53 RNA genes.

ABSTRACT The Sulfolobales archaea have been found inhabiting acidic hot springs all over the world. Here, we report the 1.798-Mbp draft genome sequence of the thermoacidophilic Sulfolobales archaeon AZ1, reconstructed from the metagenome of a Mexican hot spring. Sequence-based comparisons revealed that the Sulfolobales archaeon AZ1 represents a novel candidate genus.

ABSTRACT We report the draft 3.675-Mbp genome sequence of “ Candidatus Halobonum tyrrellensis” strain G22, a novel halophilic archaeon isolated from the surface hypersaline waters of Lake Tyrrell, Australia. The availability of the first genome from the “ Candidatus Halobonum” genus provides a new genomic resource for the comparative genomic analysis of halophilic Archaea .

ABSTRACT “ Candidatus Methanomassiliicoccus intestinalis” Issoire-Mx1 is a methanogenic archaeon found in the human gut and is a representative of the novel order of methanogens related to Thermoplasmatales . Its complete genome sequence is presented here.
