Globuloviridae

Today, Globuloviridae has become a topic of great relevance and interest to a wide variety of people around the world. Since its emergence, Globuloviridae has generated discussions and debates about its impact on society, culture and the economy. As we move into the 21st century, Globuloviridae continues to be a topic that arouses curiosity and attention, as its influence extends to different aspects of daily life. In this article, we will explore in depth the meaning and importance of Globuloviridae, as well as its relationship with other topics and its relevance in the current context.

Globuloviridae is a family of hyperthermophilic archaeal viruses. Crenarchaea of the genera Pyrobaculum and Thermoproteus (both in Thermoproteaceae) serve as natural hosts. There are four species in this family, assigned to a single genus, Alphaglobulovirus.

Taxonomy

The family contains one genus which contains four species:

Structure

Virions in the Globuloviridae are spherical and enveloped. The diameter is around 100 nm.

Genomes are linear dsDNA and non-segmented, around 20–30kb in length.

Genus Structure Symmetry Capsid Genomic arrangement Genomic segmentation
Alphaglobulovirus Spherical Enveloped Linear Monopartite

Life cycle

Viral replication is cytoplasmic. DNA-templated transcription is the method of transcription. Pyrobaculum and Thermoproteus archaea serve as the natural host. Transmission routes are passive diffusion.
