The rapidly expanding universe of giant viruses: Mimivirus, Pandoravirus, Pithovirus and Mollivirus [PDF]

FEMS Microbiology Reviews, 2015
More than a century ago, the term 'virus' was introduced to describe infectious agents that are invisible by light microscopy and capable of passing through sterilizing filters. In addition to their extremely small size, most viruses have minimal genomes and gene contents, and rely almost entirely on host cell-encoded functions to multiply ...

Draft Genome Sequence of Pandoravirus japonicus Isolated from the Sabaishi River, Niigata, Japan

Microbiology Resource Announcements, 2021
“ Pandoraviridae ” is a proposed family of the phylum Nucleocytoviricota . Its features include an amphora-shaped capsid and the largest genome among all viruses. We report the isolation and genome sequencing of a new member of this family, named Pandoravirus japonicus

Pleistocene glacial and interglacial ecosystems inferred from ancient DNA analyses of permafrost sediments from Batagay megaslump, East Siberia

Environmental DNA, Volume 4, Issue 6, Page 1265-1283, November 2022., 2022
As the past is the key to the future, to understand community transformations and ecological interactions, we reconstructed ecosystem‐wide biotic composition (from viruses to megaherbivores) between glacials and interglacials from the Middle and Late Pleistocene at the Batagay megaslump, east Siberia.

Whole‐plant microbiome profiling reveals a novel geminivirus associated with soybean stay‐green disease

Plant Biotechnology Journal, Volume 20, Issue 11, Page 2159-2173, November 2022., 2022
Summary Microbiota colonize every accessible plant tissue and play fundamental roles in plant growth and health. Soybean stay‐green syndrome (SGS), a condition that causes delayed leaf senescence (stay‐green), flat pods and abnormal seeds of soybean, has become the most serious disease of soybean in China.

Whole-Genome Sequencing of a Pandoravirus Isolated from Keratitis-Inducing Acanthamoeba [PDF]

Genome Announcements, 2015
ABSTRACT Following the recent discovery of two Pandoravirus species in 2013, a previously described endocytobiont isolated from the inflamed eye of a patient with keratitis was subjected to whole-genome sequencing (WGS). Here, we present the complete genome sequence of a new Pandoravirus

Nasopharyngeal virome analysis of COVID‐19 patients during three different waves in Campania region of Italy

Journal of Medical Virology, Volume 94, Issue 5, Page 2275-2283, May 2022., 2022
Abstract From December 2019, severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) infection has spread rapidly, leading to a global pandemic. Little is known about possible relationships between SARS‐CoV‐2 and other viruses in the respiratory system affecting patient prognosis and outcomes.

Metagenomic analysis of primary colorectal carcinomas and their metastases identifies potential microbial risk factors

Molecular Oncology, Volume 15, Issue 12, Page 3363-3384, December 2021., 2021
This work analysed the presence of sequences of bacteria and viruses in primary colorectal cancer (CRC) tissues, compared with corresponding normal colorectal tissues and metastases. We observed a higher viral species diversity and lower bacterial species diversity in primary CRCs than in matched normal tissues.

Evolution of giant pandoravirus from small icosahedral viruses revealed by CRISPR/Cas9

, 2022
Giant viruses (GVs) are a hotspot of unresolved controversies since their discovery, including the definition of “Virus” and the existence of a fourth domain of life1-3. While increasing knowledge of genome diversity has accumulated4, functional genomics was largely neglected.

Zooming on dynamics of marine microbial communities in the phycosphere of Akashiwo sanguinea (Dinophyta) blooms

Molecular Ecology, Volume 30, Issue 1, Page 207-221, January 2021., 2021
Abstract Characterizing ecological relationships between viruses, bacteria and phytoplankton in the ocean is critical to understanding the ecosystem; however, these relationships are infrequently investigated together. To understand the dynamics of microbial communities and environmental factors in harmful algal blooms (HABs), we examined the ...
