Abstract
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.

Ecophysiology and interactions of a taurine-respiring bacterium in the mouse gut

Taurinivorans Taurinivorans muris Ts
Abstract
AbstractTaurine-respiring gut bacteria produce H2S with ambivalent impact on host health. We report the isolation and ecophysiological characterization of a taurine-respiring mouse gut bacterium. Taurinivorans muris strain LT0009 represents a new widespread species that differs from the human gut sulfidogen Bilophila wadsworthia in its sulfur metabolism pathways and host distribution. T. muris specializes in taurine respiration in vivo, seemingly unaffected by mouse diet and genotype, but is dep

Ecogenomics and cultivation reveal distinctive viral-bacterial communities in the surface microlayer of a Baltic Sea slick

“Alishewanella slickus”
Abstract
AbstractVisible surface films, termed slicks, can extensively cover freshwater and marine ecosystems, with coastal regions being particularly susceptible to their presence. The sea-surface microlayer (SML), the upper 1-mm at the air-water interface in slicks (herein slick SML) harbors a distinctive bacterial community, but generally little is known about SML viruses. Using flow cytometry, metagenomics, and cultivation, we characterized viruses and bacteria in a brackish slick SML in comparison t

Metagenomics Revealed a New Genus ‘Candidatus Thiocaldithrix dubininis’ gen. nov., sp. nov. and a New Species ‘Candidatus Thiothrix putei’ sp. nov. in the Family Thiotrichaceae, Some Members of Which Have Traits of Both Na+- and H+-Motive Energetics

Ca. Thiothrix putei Ca. Thiocaldithrix dubininis
Abstract
Two metagenome-assembled genomes (MAGs), GKL-01 and GKL-02, related to the family Thiotrichaceae have been assembled from the metagenome of bacterial mat obtained from a sulfide-rich thermal spring in the North Caucasus. Based on average amino acid identity (AAI) values and genome-based phylogeny, MAG GKL-01 represented a new genus within the Thiotrichaceae family. The GC content of the GKL-01 DNA (44%) differed significantly from that of other known members of the genus Thiothrix (50.1–55.6%).

A novel, tissue-associated and vertically transmitted bacterial symbiont in the coralPocillopora acuta

Maire et al. (2023).

Abstract
AbstractCoral microhabitats are colonized by a myriad of microorganisms, including diverse bacteria which are essential for host functioning and survival. However, the location, transmission, and functions of individual bacterial species living inside the coral tissues remain poorly studied. Here, we show that a previously undescribed bacterial symbiont of the coralPocillopora acutaforms cell-associated microbial aggregates (CAMAs) within the mesenterial filaments. CAMAs were found in both adult

Genome Comparison of ‘Candidatus Phytoplasma rubi’ with Genomes of Other 16SrV Phytoplasmas Highlights Special Group Features

Abstract
Phytoplasmas are associated with important bacterial diseases, causing severe symptoms in agricultural and ornamental crops. ‘Candidatus Phytoplasma rubi’, associated with the Rubus stunt in raspberries (Rubus idaeus) and blackberries (Rubus subgenus Rubus), causes shortened internodes, elongated sepals, proliferation, phyllody, and virescence. The recently published genome of ‘Ca. P. rubi’ RS enabled a comprehensive genomic comparison to the complete genomes of 16SrV phytoplasmas, comprising st

Seasonal Patterns in the Frequency of Candidatus Liberibacter Asiaticus in Populations of Diaphorina citri (Hemiptera: Psyllidae) in Florida

Ca. Liberibacter asiaticus Liberibacter
Abstract
Candidatus Liberibacter asiaticus (CLas) is one of the putative causal agents of huanglongbing, which is a serious disease in citrus production. The pathogen is transmitted by Diaphorina citri Kuwayama (Hemiptera: Psyllidae). As an observational study, six groves in central Florida and one grove at the southern tip of Florida were sampled monthly from January 2008 through February 2012 (50 months). The collected psyllids were sorted by sex and abdominal color. Disease prevalence in adults peaked

‘Candidatus Phytoplasma ziziphi’ Changes the Metabolite Composition of Jujube Tree Leaves and Affects the Feeding Behavior of Its Insect Vector Hishimonus hamatus Kuoh

Citation

Names
Ca. Phytoplasma ziziphi
Abstract
Hishimonus hamatus Kuoh is a leafhopper species native to China that feeds on Chinese jujube leaves. This leafhopper species has been verified to transmit jujube witches’ broom (JWB) disease, caused by phytoplasma, a fatal plant pathogen, which belongs to the phytoplasma subgroup 16SrV-B. The transmission of JWB phytoplasma largely relies on the feeding behavior of piercing–sucking leafhoppers. However, the specific mechanisms behind how and why the infection of JWB influences the feeding behavi
