These are large (100–560 kb) double-stranded DNA viruses with icosahedral shaped capsids. By 2014, 33 species divided into six genera had been identified within the family, [50] [51] which belongs to a super-group of large viruses known as nucleocytoplasmic large DNA viruses.
[1] [2] This family belongs to a super-group of large viruses known as nucleocytoplasmic large DNA viruses. Evidence was published in 2014 suggesting that specific strains of Phycodnaviridae might infect humans rather than just algal species, as was previously believed. [3]
The viruses that store their genomic information using DNA, DNA viruses, are the best studied subgrouping of algae-infecting viruses This is especially true for the dsDNA virus family, Phycodnaviridae. [1] [3] However, other groups of dsDNA viruses including giant viruses belonging to the family Mimiviridae also infect algae. [3]
Orthopoxvirus particles. A DNA virus is a virus that has a genome made of deoxyribonucleic acid (DNA) that is replicated by a DNA polymerase.They can be divided between those that have two strands of DNA in their genome, called double-stranded DNA (dsDNA) viruses, and those that have one strand of DNA in their genome, called single-stranded DNA (ssDNA) viruses. dsDNA viruses primarily belong ...
Viruses are the most abundant life in the ocean, harboring the greatest reservoir of genetic diversity. [256] As their infections are often fatal, they constitute a significant source of mortality and thus have widespread influence on biological oceanographic processes, evolution and biogeochemical cycling within the ocean.

Virosphere (virus diversity, virus world, global virosphere) was coined to refer to all those places in which viruses are found or which are affected by viruses. [1] [2] However, more recently virosphere has also been used to refer to the pool of viruses that occurs in all hosts and all environments, [3] as well as viruses associated with specific types of hosts (prokaryotic virosphere, [4 ...
Deaths from a handful of viruses that spill over from animals to humans are set to increase 12-fold by 2050 due to climate change and habitat encroachment, according to a new study published in ...
