Microbial regulation of global macroalgal blooms (green tides): From holobiont interactions to bloom dynamics and biogeochemistry

Limnology and Oceanography Letters, Volume 11, Issue 2, March 2026.
Abstract Green tides caused by Ulva species have become one of the most serious marine ecological disasters, now impacting many coastal nations around the world. Although climatic and environmental drivers of these macroalgal blooms are well recognized, growing evidence identifies Ulva‐associated microbiota as potential pivotal regulators of bloom ...

Single-Stranded DNA Viruses in Antarctic Cryoconite Holes

Viruses, 2019
Antarctic cryoconite holes, or small melt-holes in the surfaces of glaciers, create habitable oases for isolated microbial communities with tightly linked microbial population structures. Viruses may influence the dynamics of polar microbial communities,

Viral DNA genomes in sera of farrowing sows with or without stillbirths.

PLoS ONE, 2020
A study was conducted to investigate the serum virome of sows with and without stillbirths after farrowing. Sera from sows with at least one stillbirth or with normal litters were collected immediately after farrowing.

Unveiling Crucivirus Diversity by Mining Metagenomic Data

mBio, 2020
The discovery of cruciviruses revealed the most explicit example of a common protein homologue between DNA and RNA viruses to date. Cruciviruses are a novel group of circular Rep-encoding single-stranded DNA (ssDNA) (CRESS-DNA) viruses that encode capsid

Development and Application of a Rep‐Targeted SYBR Green I qPCR Assay for Porcine Circovirus 4: Etiological Investigation in China (2022–2025) and Molecular Evolutionary Analysis

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Porcine circovirus (PCV) type 4 (PCV4) is an emerging Circovirus whose epidemiological and evolutionary dynamics remain incompletely characterized. We developed a replication‐associated protein (Rep)‐targeted SYBR Green I real‐time quantitative PCR assay that showed analytical specificity against tested common porcine pathogens and an estimated 95 ...

Circular replication-associated protein-encoding single-stranded DNA virus with risk of spillover is widely prevalent in domestic animals in China

Virus Research
Circular replication-associated protein (Rep)-encoding single-stranded (CRESS) DNA viruses are highly diverse and have a broad range of hosts. In this study, we report the detection of Bo-Circo-like virus AH20-1 in the feces of diarrheal cattle.

Emerging Challenges and Advances in Porcine Circovirus: A Decade in Review

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Over the past decade, porcine circoviruses (PCVs) have continued to pose a significant threat to global swine health, and pivotal discoveries have significantly reshaped our understanding of their biology and control. Extensive genomic surveillance has expanded porcine circovirus 2 (PCV2) genotyping from four to at least eight lineages, with PCV2d now ...

T2T Genomes Unveil Centromere Architecture and Adaptive Divergence in Large Yellow Croaker (Larimichthys crocea)

Advanced Science, Volume 12, Issue 43, November 20, 2025.
This study presents telomere‐to‐telomere genome assemblies for two populations of Larimichthys crocea. We identified centromere‐specific tandem repeats invaded by LTR/ERV1 retrotransposons, unique 5S rRNA enrichment patterns, and population‐specific structural variants. Comparative genomic analyses further reveal distinct adaptive mechanisms in the MYD

Genome editing in the green alga Chlamydomonas: past, present practice and future prospects

The Plant Journal, Volume 122, Issue 1, April 2025.
SUMMARY The green alga Chlamydomonas is an important and versatile model organism for research topics ranging from photosynthesis and metabolism, cilia, and basal bodies to cellular communication and the cellular cycle and is of significant interest for green bioengineering processes. The genome in this unicellular green alga is contained in 17 haploid
