ABSTRACT Candidatus Loosdrechtia sp. KJ is an anaerobic ammonium-oxidizing bacterium enriched from a bioreactor operated under alkaline conditions (pH 9.2 ± 0.4). We report its 3.39 Mb draft genome, containing 3,065 predicted coding sequences, 47 tRNA genes, and a single rrn operon.

ABSTRACT Five draft genome sequences of ‘ Candidatus Liberibacter solanacearum’ haplotype E from five different Bactericera trigonica vector insects sampled in France are reported. Each genome has a size of about 1.20 Mbp, a G + C content of 35% and approximately 1,000 predicted coding DNA sequences.

ABSTRACT We report the draft genomes of five Clostridium isolates from soil and agricultural by-products, four of which are proposed as Candidatus species. Members of the genus Clostridium are of significant industrial interest, and the availability of their genome sequences facilitates the understanding and exploration of their functional potential.

ABSTRACT The complete genome, 226,287 bps in size, of “ Candidatus Nardonella sp.” Pin-AIST, an obligatory bacterial endosymbiont of the black hard weevil Pachyrhynchus infernalis , was sequenced. The extremely reduced endosymbiont genome is specialized for tyrosine synthesis, which contributes to the hardness of the beetle’s exoskeleton.

ABSTRACT The complete genome, 173,958 bp in size, of “ Candidatus Carsonella ruddii” DC-OKEB1 , an obligate bacterial endosymbiont of the Asian citrus psyllid Diaphorina citri , was determined. The genome sequence provides valuable information for comparative and evolutionary aspects of the intimate insect–microbe mutualism.

ABSTRACT “Candidatus Dehalogenimonas loeffleri” strain W, isolated from estuarine sediments, can dechlorinate 1,2-dichloroethane under high salinity. Its genome consists of a circular 1,772,240-bp chromosome with a G + C content of 52.5% and encompasses 1,763 protein-coding sequences, including 28 genes encoding reductive dehalogenases.

ABSTRACT The complete genome of “ Candidatus Phytoplasma solani” GOE was obtained from the infected vector Pentastiridius leporinus by single-molecule real-time sequencing. This 16SrXII-P phytoplasma is associated with the economically important sugar beet disease “syndrome basses richesses.” The genome sequence is an essential resource for diagnosis and understanding pathogen–host interaction.

ABSTRACT The Chichon volcano contains several thermal manifestations including an acidic crater lake. Here we report a metagenome-assembled genome of “ Candidatus Aramenus sp. CH1,” a Sulfolobales archaeon inhabiting the crater lake from the Chichon volcano. In this study, we generated a novel Aramenus genome sequence from a thermal area in Southern Mexico.

ABSTRACT This study reports a circular metagenome-assembled genome (cMAG) of Candidatus Cloacimonadota recovered from a mesophilic full-scale food waste treatment plant. The cMAG spans 2,298,113 bp, with 980× coverage and 1 contig.

ABSTRACT The complete genome of “ Candidatus Phytoplasma fraxini” AshY1, originating from Fraxinus americana in North America, was assembled using long reads from single-molecule real-time sequencing technology. The chromosome of 598 kb provides insights into the effector repertoire of a phytopathogenic bacterium from the 16SrVII phytoplasma group.
