Dozens of giant viruses have been surprisingly discovered since 2003. Giant viruses are notably larger than typical bacteria and have extremely large genomes that encode thousands of genes. Because the giant viruses have super-sized shapes and genome sizes, they are distinguished from classical viruses and bacteria. The evolutionary origin of the giant virus is still an open question. The current phylogenetic studies on giant virus use specific genes or proteins, and can not elucidate the origins of the giant viruses from the global genome perspective. In this study, we perform the whole-genome phylogenetic analysis of the giant viruses using the Fourier transform-based alignment-free method. The phylogenetic analysis shows that the typical giant virus Pandoravirus and tailed giant virus Tupanvirus are closely related to archaea. This new finding suggests that giant viruses may origin from archaea and supports the reductive model on the giant virus evolution. |
