The giant Pandora virus specializes in creating new genes

have discovered three new Pandora's viruses and found that they have many "orphan genes" in their vast genomes. This means that Pandora's virus may be good at creating entirely new genes.
Pandora virus, a giant virus that was only discovered in 2013, is found in amoegams and resembles bacteria. It ranks second in the viral world in size and first in genome size.
A team of researchers at the French National Centre for Scientific Research has discovered three more, from France, Australia and New Caledonia in the South Pacific, following the first discovery of two Pandora's viruses in 2013, according to a press release from France's National Centre for Scientific Research. The team compared the genomes of the six Pandora's viruses with another Pandora virus from Germany that other researchers found.
in their paper, published in the British journal
, they say the viruses come from very different sources and are similar in form and function, but the genome is not very similar, and only half of the genes that encode proteins are the same. Each virus has many unique "orphan genes", i.e. genes that do not find similar sequences in other organisms and appear to be unpromising.
is generally believed that all living things on Earth share a common ancestor, and that most genes have highly similar esoteric genes in all kinds of organisms. But Pandora's virus has a particularly large number of "orphan genes" and varies from species to species, unlikely to be of the same origin.
found that pandora's "orphan genes" are structurally similar to regions of the genome that do not encode proteins, possibly spontaneously and randomly from non-coding regions. These genes are not inherited from ancestors, but are new inventions of each virus. If confirmed, this point means that Pandora's virus is particularly good at genetic innovation.
