Unveiling new uncultivated giant viruses. another group of viruses whose known diversity has been vastly expanded through metagenomics are the so called “giant viruses”, dsdna viruses with a uniquely large virion (~0.5–1 µm) and genome (often >1 mb), blurring the boundaries between “simple” viruses and “complex” cellular life. A giant virus, also known as a girus, is a very large virus, some of which are larger than typical bacteria. they have extremely large genomes compared to other viruses and contain many unique genes not found in other life forms. all known giant viruses belong to the phylum nucleocytoviricota (nucleocytoplasmic large dna viruses, ncdlvs); they are the larger members of this group description.
