Phylogenetic Analysis of Members of the Phycodnaviridae Virus Family, Using Amplified Fragments of the Major Capsid Protein Gene [PDF]
Applied and Environmental Microbiology, 2008 ABSTRACT Algal viruses are considered ecologically important by affecting host population dynamics and nutrient flow in aquatic food webs. Members of the family Phycodnaviridae are also interesting due to their extraordinary genome size.

KEGG tools for classification and analysis of viral proteins
Protein Science, Volume 32, Issue 12, December 2023., 2023 Abstract The KEGG database and analysis tools (https://www.kegg.jp) have been developed mostly for understanding genes and genomes of cellular organisms. The KO (KEGG Orthology) dataset, which is a collection of functional orthologs, plays the role of linking genes in the genome to pathways and other molecular networks, enabling KEGG mapping to uncover

Novel virophages discovered in a freshwater lake in China
Frontiers in Microbiology, 2016 Virophages are small double-stranded DNA viruses that are parasites of giant DNA viruses that infect unicellular eukaryotes. Here we identify a novel group of virophages, named Dishui Lake virophages (DSLVs) that were discovered in Dishui Lake (DSL): an ...

Multiple infections of zoonotic pathogens in wild Brandt's voles (Lasiopodomys brandtii)
Veterinary Medicine and Science, Volume 9, Issue 5, Page 2201-2211, September 2023., 2023 Our research revealed the viral and bacterial diversity in wild Brandt's voles. The characterization and distinctive lineage of some rodent‐specific viruses (Cytomegalovirus, PestVs and Lentiviruses) and rodent‐borne bacteria (Leptospira interrogans and Vibrio cholerae) indicates that wild Brandt's voles may harbor a diversity of viruses and bacteria ...

Genomic comparison of closely related Giant Viruses supports an accordion-like model of evolution.
Frontiers in Microbiology, 2015 Genome gigantism occurs so far in Phycodnaviridae and Mimiviridae (order Megavirales). Origin and evolution of these Giant Viruses (GVs) remain open questions.

Identification of Freshwater Phycodnaviridae and Their Potential Phytoplankton Hosts, Using DNA pol Sequence Fragments and a Genetic-Distance Analysis [PDF]
Applied and Environmental Microbiology, 2009 ABSTRACT Viruses that infect phytoplankton are an important component of aquatic ecosystems, yet in lakes they remain largely unstudied. In order to investigate viruses ( Phycodnaviridae ) infecting eukaryotic phytoplankton in lakes and to estimate the number of potential host species, samples were ...

Metagenomic Analysis of Virus Diversity and Relative Abundance in a Eutrophic Freshwater Harbour
Viruses, 2019 Aquatic viruses have been extensively studied over the past decade, yet fundamental aspects of freshwater virus communities remain poorly described. Our goal was to characterize virus communities captured in the >0.22 µm size-fraction seasonally ...

Extension of the viral ecology in humans using viral profile hidden Markov models. [PDF]
PLoS ONE, 2018 When human samples are sequenced, many assembled contigs are "unknown", as conventional alignments find no similarity to known sequences. Hidden Markov models (HMM) exploit the positions of specific nucleotides in protein-encoding codons in various ...

Unveiling of the Diversity of Prasinoviruses (Phycodnaviridae) in Marine Samples by Using High-Throughput Sequencing Analyses of PCR-Amplified DNA Polymerase and Major Capsid Protein Genes [PDF]
Applied and Environmental Microbiology, 2014 ABSTRACT Viruses strongly influence the ecology and evolution of their eukaryotic hosts in the marine environment, but little is known about their diversity and distribution. Prasinoviruses infect an abundant and widespread class of phytoplankton, the Mamiellophyceae, and thereby exert a specific and important role in microbial ...
