"Exogenous viral genes may represent an important force in the evolution of eukaryotes." https://t.co/QqLGzOPBO6
"Several non-retroviral viruses have also contributed to the genetic makeup of many eukaryotic organisms." https://t.co/QqLGzOPBO6
"Integrated phages (prophages) accounting for as much as 10-20% of some bacterial genomes." https://t.co/QqLGzOPBO6
"It is widely accepted that phages represent substantial forces in prokaryotic evolution." https://t.co/QqLGzOPBO6
"The integrated retroviral genes have been demonstrated to play critical role in mammalian reproduction." https://t.co/QqLGzOPBO6
"Unlike retroviruses, few members of other virus families are known to transfer genes to host genomes." https://t.co/QqLGzOPBO6
Retroviruses "comprise approximately 8% of the human genome." https://t.co/QqLGzOPBO6
Retroviruses "can integrate into host genome as an obligate step in their replication strategy." https://t.co/QqLGzOPBO6
"This discovery extends the host range of circular ssDNA viruses." https://t.co/QqLGzOPBO6
"The genes of small circular ssDNA viruses...(have been) conserved and functional in host genomes." https://t.co/QqLGzOPBO6
"The genes of small circular ssDNA viruses have been transferred into a broad range of eukaryotic genomes." https://t.co/QqLGzOPBO6
HGT. "It has been suggested that phages represent substantial forces in prokaryotic evolution." https://t.co/QqLGzOPBO6
HGT. "organisms can also acquire genes...from their extra-chromosomal elements (plasmids and viruses)." https://t.co/QqLGzOPBO6
HGT. "In addition to vertical transmission, organisms can also acquire genes from other distantly related species." https://t.co/QqLGzOPBO6
