Metavirome survey of eight ray-finned fishes: Domination of giant viral members from pandoravirus and megaviricetes [PDF]

Journal of Clinical and Basic Research
Background: Fish are an essential source of food worldwide. Most microbial diversity in marine ecosystems remains uncharacterized, with viruses accounting for most of the remaining diversity.

Presence of CRISPR CAS-Like Sequences as a Proposed Mechanism for Horizontal Genetic Exchanges between Trichomonas vaginalis and Its Associated Virus: A Comparative Genomic Analysis with the First Report of a Putative CRISPR CAS Structures in Eukaryotic Cells. [PDF]

Biomed Res Int, 2023
Introduction. Trichomonas vaginalis genome is among the largest genome size and coding capacities. Combinations of gene duplications, transposon, repeated sequences, and lateral gene transfers (LGTs) have contributed to the unexpected large genomic size and diversity. This study is aimed at investigating genomic exchange and seeking for presence of the

Complex Genomes of Early Nucleocytoviruses Revealed by Ancient Origins of Viral Aminoacyl-tRNA Synthetases. [PDF]

Mol Biol Evol
Aminoacyl-tRNA synthetases (aaRSs), also known as tRNA ligases, are essential enzymes in translation. Owing to their functional essentiality, these enzymes are conserved in all domains of life and used as informative markers to trace the evolutionary ...

Unveiling Common Bean (<i>Phaseolus vulgaris</i> L) RNA- and DNA-Based Virome in Western Kenya: Insights From Metatranscriptomic and Metagenomic Signatures. [PDF]

Adv Virol
Common bean (Phaseolus vulgaris L) is Kenya’s second most important agricultural product after maize, serving as a vital source of protein for many rural families in Western Kenya. However, viral diseases caused by RNA and DNA viruses greatly impair bean productivity, often leading to yield losses of up to 100%, thus contributing to food insecurity ...

Gut Virome: What's the Role in Irritable Bowel Syndrome? [PDF]

Rev Med Virol
ABSTRACT The gut virome, an integral but still poorly understood component of the gut microbiota, is emerging as an important player in the pathophysiology of irritable bowel syndrome (IBS). Recent evidence suggests that alterations in virome diversity and phage–bacteria interactions contribute to gut dysbiosis, immune modulation and gut barrier ...

High-Throughput Sequencings Revealed That Gut Microbiota Dysbiosis is Implicated in Gouty Arthritis of Red-Crowned Crane (<i>Grus japonensis</i>). [PDF]

Transbound Emerg Dis
The red‐crowned crane (Grus japonensis) is one of the rarest cranes with a global population of less than 4000 individuals. The population of red‐crowned crane could be influenced by health threats, including metabolic and infectious diseases. In the Wildlife Rescue Center of Suining County of Jiangsu Province, gouty arthritis (GA) was observed in all ...

Protein repeats evolve and emerge in giant viruses [PDF]

, 2023
Nucleocytoplasmatic large DNA viruses (NCLDVs or giant viruses) stand out because of their relatively large genomes encoding hundreds of proteins. These species give us an unprecedented opportunity to study the emergence and evolution of repeats in ...

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.

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.
