Marine and giant viruses as indicators of a marine microbial community in a riverine system [PDF]
MicrobiologyOpen, Volume 5, Issue 6, Page 1071-1084, December 2016., 2016 Viral communities are important for ecosystem function as they are involved in critical biogeochemical cycles and controlling host abundance. This study investigates riverine viral communities around a small rural town that influences local water inputs.

Kinetic Analysis of Acanthamoeba castellanii Infected with Giant Viruses Quantitatively Revealed Process of Morphological and Behavioral Changes in Host Cells [PDF]
Microbiology Spectrum, 2021 Most virus-infected cells show morphological and behavioral changes, which are called cytopathic effects. Acanthamoeba castellanii, an abundant, free-living protozoan, serves as a laboratory host for some viruses of the phylum Nucleocytoviricota—the ...

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.

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 EvolAminoacyl-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 VirolCommon 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 ...
