Discovery and characterization of complete genomes of 38 head-tailed proviruses in four predominant phyla of archaea

Microbiology Spectrum
Archaea play a significant role in natural ecosystems and the human body. Archaeal viruses exert a considerable influence on the structure and composition of archaeal communities and their associated ecological environments.

Investigating GERMs: how genotype, environment, and rhizosphere microbiome interactions underlie heat response in maize and sorghum

New Phytologist, EarlyView.
Three genotypes – a heat‐resistant maize (Zea mays), a heat‐susceptible maize, and a sorghum (Sorghum bicolor) variety – were grown to the V4 stage in growth chambers under optimal conditions or subjected to heat stress. Plants were grown in soil containing a complex microbial community, or in the same soil with a depleted microbiome.

An archaeal chronic virus escapes the immunity of prokaryotic Argonaute

Nucleic Acids Research
Abstract Bacteria and archaea use diverse defense systems to defeat their viruses, and in turn, viruses develop anti-defense strategies to overcome the host immunity. Catalytically inactive prokaryotic Argonaute proteins constitute a family of defense systems that kill infected cells to halt viral propagation, whereas how viruses escape ...

Advances in large DNA fragment assembly for microbial cell factory engineering

Quantitative Biology, Volume 14, Issue 3, September 2026.
Abstract The efficient, rapid, and reliable assembly of DNA fragments is essential for advancing metabolic engineering and synthetic biology. With the rapid advancement of DNA synthesis and assembly technologies, the scale of DNA assembly has expanded from single genes to metabolic pathways and even genomes.

Host-Dependent Differences in Replication Strategy of the Sulfolobus Spindle-Shaped Virus Strain SSV9 (a.k.a., SSVK1): Infection Profiles in Hosts of the Family Sulfolobaceae

Frontiers in Microbiology, 2020
The Sulfolobus Spindle-shaped Virus (SSV) system has become a model for studying thermophilic virus biology, including archaeal host-virus interactions and biogeography. Several factors make the SSV system amenable to studying archaeal genetic mechanisms

Intratumoral Microbiota in Tumor: Current Understandings and Future Perspectives

MedComm, Volume 7, Issue 7, July 2026.
Intratumoral bacteria are emerging as active regulators of cancer evolution rather than bystanders. This review outlines how tumor‐resident microbes drive tumor initiation and growth by inducing genomic instability, epigenetic reprogramming, oncogenic signaling, and chronic inflammation, while promoting metastatic spread via invasion, angiogenesis ...

ORF157 from the Archaeal VirusAcidianusFilamentous Virus 1 Defines a New Class of Nuclease [PDF]

Journal of Virology, 2010
ABSTRACTAcidianusfilamentous virus 1 (AFV1) (Lipothrixviridae) is an enveloped filamentous virus that was characterized from a crenarchaeal host. It infectsAcidianusspecies that thrive in the acidic hot springs (>85°C and pH <3) of Yellowstone National Park, WY. The AFV1 20.8-kb, linear, double-stranded DNA genome encodes 40 putative open reading

Nature's Nanotech Warriors: The Role of Metalloproteins and Protein Cages for Environmental Remediation

Advanced Sustainable Systems, Volume 10, Issue 6, June 2026.
Cartoon representation of five major classes of metalloproteins and their brief mechanisms of bioremediation. The five classes include metallothioneins, metal‐precipitating enzymes, P.‐type ATPases, protein cages, and synthetic metalloproteins (de novo‐designed proteins/peptides for selective adsorption). These natural and engineered protein structures

Gemella morbillorum Promotes Colorectal Carcinogenesis: LPBDCP‐Mediated Invasion Activates Ras Signaling and Destabilizes p53

Advanced Science, Volume 13, Issue 34, 19 June 2026.
ABSTRACT Gut microbiota dysbiosis promotes colorectal cancer (CRC) tumorigenesis. A global fecal metagenomic analysis identified Gemella morbillorum as a key contributor to the CRC‐associated microbiota. Fluorescence in situ hybridization revealed that Gemella morbillorum is enriched in CRC tumor tissues compared to adjacent normal tissues.
