Interplay of intracellular and trans‐cellular DNA methylation in natural archaeal consortia

Environmental Microbiology Reports, Год журнала: 2024, Номер 16(2)

Опубликована: Апрель 1, 2024

Abstract DNA methylation serves a variety of functions across all life domains. In this study, we investigated archaeal methylomics within tripartite xylanolytic halophilic consortium. This consortium includes Haloferax lucertense SVX82, Halorhabdus sp. SVX81, and an ectosymbiotic Candidatus Nanohalococcus occultus SVXNc, nano‐sized archaeon from the DPANN superphylum. We utilized PacBio SMRT Illumina cDNA sequencing to analyse samples consortia different compositions for transcriptomics. Endogenous c TAG methylation, typical , was accompanied in strain by at four other motifs, including GDG HC which is specific ectosymbiont. Our analysis distribution methylated unmethylated motifs suggests that autochthonous cTAG may influence gene regulation. The frequency GRAGA G increased highly expressed genes, while C TTG GTCG GG could be linked restriction‐modification (RM) activity. Generally, RM activity might have been reduced during evolution balance protection cells intruders, reduction damage due self‐restriction stressful environments, benefits exchange under extreme conditions. methylomics, transcriptomics complementary electron cryotomography (cryo‐ET) data suggest nanohaloarchaeon exports its methyltransferase methylate genome, unveiling new aspect interaction between symbiont host.

The regulation of tobacco growth under preceding crop planting: insights from soil quality, microbial communities, and metabolic profiling

Frontiers in Plant Science, Год журнала: 2025, Номер 16

Specific microorganisms and metabolites in soil play key roles regulating organismal behavior. Currently, the effects of different preceding crops on rhizosphere quality flue-cured tobacco remain unclear. Four treatments were compared study: fallow + (CK), maize (T1), rapeseed (T2), wheat (T3). Results showed that significantly enhanced nutrient levels improved growth by altering microbial community structure. Previous cultivation promoted growth, diversity bacterial communities, notably decreased abundance urea-degrading bacteria. In contrast, crop reduced plant pathogenic fungi positive interactions. Metabolomics analysis altered lipids, organic acids, flavonoids, alkaloids, terpenoids, enhancing secondary metabolite synthesis pathways soil. Preceding regulated which potentially participated carbon nitrogen cycling, balancing nutrients, improving yield. Overall, three composition function structures soil, thereby increased concentration. Both boosted biomass. These findings offer new insights into potential interactions between communities strategies comprehensively growth.

Pseudomonads coordinate innate defense against viruses and bacteria with a single regulatory system

bioRxiv (Cold Spring Harbor Laboratory), Год журнала: 2025, Номер unknown

Опубликована: Фев. 27, 2025

Bacterial cells live under the constant existential threats imposed by other bacteria and viruses. Their mechanisms for contending with these are well documented; however, regulation of diverse defense elements remains poorly understood. Here we show that can mount a genome-wide, coordinated, highly effective immune response against bacterial viral using single regulatory pathway. Bioinformatic analyses revealed Pseudomonas species broadly possess specialized form Gac/Rsm pathway (GRP), which our prior work in aeruginosa implicated activating interbacterial antagonism to neighbor cell death. Proteomic studies comparing GRP-activated -inactivated strains derived from showed regulates large variable suite factors both phage threats. Focusing on P. protegens, identify profound phenotypic consequences multiple forms several phage. Together, results reveal bacteria, like more complex organisms, couple danger sensing activation an system antibacterial antiviral arms.

Metagenomic selections reveal diverse antiphage defenses in human and environmental microbiomes

bioRxiv (Cold Spring Harbor Laboratory), Год журнала: 2025, Номер unknown

Опубликована: Март 1, 2025

To prevent phage infection, bacteria have developed an arsenal of antiphage defense systems. Using functional metagenomic selections, we identified new examples these systems from human fecal, oral, and grassland soil microbiomes. Our selections in Escherichia coli revealed over 200 putative defenses 14 diverse bacterial phyla, highlighting the broad phylogenetic interoperability Many were unrecognizable based on sequence or predicted structure, so could only be via assays. In mechanistic studies, show that some encode nucleases degrade covalently modified DNA, but which accommodate chemical modifications. We also identify outer membrane proteins adsorption a set previously unknown with profiles modalities. Most acted against at least two phages, indicating broadly acting are widely distributed among non-model bacteria.

Mutations in Gordonia amarae mycolic acid biosynthetic pathway confer resistance to Patescibacteria parasite Mycosynbacter amalyticus

Nature Communications, Год журнала: 2025, Номер 16(1)

Опубликована: Март 5, 2025

The obligate necrotrophic parasite, Candidatus Mycosynbacter amalyticus, a member of the Patescibacteria has been isolated from wastewater. Subsequent efforts have directed toward unravelling its biological lifecycle and attachment mechanism facilitating infection subsequent lysis Actinobacterial host, Gordonia amarae. Here, using electron cryo-tomography (CryoET), we reveal molecular anatomy parasitic amalyticus cells, uncovering an unusual process. Through laboratory-based evolution experiments, generated eleven slow-growing independent spontaneous amarae resistant mutants. Mycolic acids (MA) are key components outer cellular envelope G. other Actinobacteria, with MA being physical attribute implicated in associated wastewater foaming. CryoET genome sequencing exposed absence intact suite mutations predominantly occurring within pks13 pptT genes biosynthetic pathway. Our findings suggest that structural integrity is critical for Ca. to host.
