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 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.

ABSTRACT The genome of “ Candidatus Xenohaliotis californiensis” was assembled from shotgun metagenomic sequencing of experimentally infected white abalone. Ninety-one percent genome completeness was achieved with low contamination. Sequencing this genome provides the opportunity to track pathogen evolution over time, conduct gene expression experiments, and study dynamics between this pathogen and its phage.

ABSTRACT A single-contig, circular metagenome-assembled genome (cMAG) of Candidatus ( Ca. ) Patescibacteria was reconstructed from a mesophilic full-scale food waste treatment plant in Japan. The genome is of small size and lacks fundamental biosynthetic pathways. Taxonomic analysis using the Genome Taxonomy Database revealed that this cMAG belonged to the genus JAEZRQ01 ( Ca . Parcubacteria).

ABSTRACT A slow growing species of nontuberculous mycobacteria (NTM) was isolated from the liver of an Amazon milk frog. The complete genome of this isolate comprises 5,102,433 bp, exhibiting 66.86% GC content, 4,940 protein-coding sequences, 52 predicted RNA genes, and 39 repeat regions.

ABSTRACT The complete genome sequence of “ Candidatus Phytoplasma cynodontis” strain GY2015, which consists of one 498,922-bp circular chromosome, is presented in this work. This uncultivated plant-pathogenic bacterium is associated with Bermuda grass white leaf disease in Taoyuan, Taiwan.

ABSTRACT The genomes of obligate bacterial co-symbionts of the green rice leafhopper Nephotettix cincticeps , which is notorious as an agricultural pest, were determined. The streamlined genomes of “ Candidatus Sulcia muelleri” and “ Candidatus Nasuia deltocephalinicola” exhibited complementary metabolic pathways for synthesizing essential nutrients that contribute to host adaptation.
