This work proposes a mathematical framework that integrates dynamical systems, environmental stress formalism, and biological spacetime to explore the origins of cellular complexity. It examines the emergence of eukaryotes as a potential outcome of forced genetic interactions, identifying the golden ratio as a significant threshold in evolutionary ...

Genomic comparison of closely related Giant Viruses supports an accordion-like model of evolution. [PDF]
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.

A giant virus infecting the amoeboflagellate Naegleria. [PDF]
Nat CommunAbstractGiant viruses (Nucleocytoviricota) are significant lethality agents of various eukaryotic hosts. Although metagenomics indicates their ubiquitous distribution, available giant virus isolates are restricted to a very small number of protist and algal hosts.

Giant variations in giant virus genome packaging
Trends in Biochemical Sciences, 2023 Giant viruses (Nucleocytoviricota) have a largely conserved lifecycle, yet how they cram their large genomes into viral capsids is mostly unknown. The major capsid protein and the packaging ATPase (pATPase) comprise a highly conserved morphogenesis module in giant viruses, yet some giant viruses dispense with an icosahedral capsid, and others encode ...

Asfarviruses and Closely Related Giant Viruses
Viruses, 2023 Acanthamoeba polyphaga mimivirus, so called because of its “mimicking microbe”, was discovered in 2003 and was the founding member of the first family of giant viruses isolated from amoeba.

Varicella zoster virus and giant cell arteritis [PDF]
Current Opinion in Infectious Diseases, 2016 Giant cell arteritis (GCA) is a serious disease and the most common cause of vasculitis in the elderly. Here, studies describing the recent discovery of varicella zoster virus (VZV) in the temporal arteries of patients with GCA are reviewed.GCA is characterized by severe headache/head pain and scalp tenderness.

Near-atomic structure of a giant virus. [PDF]
Nat Commun, 2019 Abstract Although the nucleocytoplasmic large DNA viruses (NCLDVs) are one of the largest group of viruses that infect many eukaryotic hosts, the near-atomic resolution structures of these viruses have remained unknown. Here we describe a 3.5 Å resolution icosahedrally averaged capsid structure of Paramecium bursaria chlorella virus 1
