SERIAL GENE ACQUISITION. "The host-to-virus direction suggests that the serial acquisition of genes involved in the same metabolic pathway might have been a strategy for the ancestor of EhVs to stay ahead of their closest relatives in the great evolutionary race for survival." http://jvi.asm.org/content/84/22/11876.short View in LinkedIn

ENTIRE PATHWAY TRANSFERAL."Horizontal gene transfer of an entire metabolic pathway between a eukaryotic alga and its DNA virus. The virus-to-host direction suggests the existence of ancient viruses that controlled the complex metabolic pathway in order to infect primitive eukaryotic cells." http://jvi.asm.org/content/84/22/11876.short View in LinkedIn

VIRUSES AND EUKARYOTES. "Our findings imply that horizontal transfer of double-stranded RNA viral genes is widespread among eukaryotes and may give rise to functionally important new genes, thus entailing that RNA viruses may play significant roles in the evolution of eukaryotes." https://lnkd.in/eCybf-m View in LinkedIn

POLARITY OF GENE TRANSFER. "Horizontal gene transfer commonly occurs from cells to viruses but rarely occurs from viruses to their host cells, with the exception of retroviruses and some DNA viruses." https://lnkd.in/eCybf-m View in LinkedIn

HORIZONTAL GENE TRANSFER. "The fixation of genes horizontally transferred is not a rampant phenomenon between organisms with substantial phylogenetic separations...>50% of Archaea have one or more protein domains acquired by HGT, and nearly 30–50% of Bacteria did the same when examined at three taxonomic ranges. But, the equivalent value for Eukarya is

MOSAIC OPERONS. "Two evolutionary scenarios for the origin of such mosaic operons are conceivable. The first involves de novo assembly of operons, in part from genes acquired via HGT, whereas the second one postulates in situ xenologous displacement of genes within a resident operon." https://lnkd.in/eRYS-TZ View in LinkedIn

"INTRAGENOMIC plasticity and inter-species horizontal mobility of operons are thought to be important facets of prokaryotic genome evolution." https://lnkd.in/eRYS-TZ View in LinkedIn

"HORIZONTAL transfer of entire operons is the most likely explanation for most of the findings of co-localized 'alien' genes in a genome." https://lnkd.in/eRYS-TZ View in LinkedIn

BRILLIANT REVIEW. "Shuffling and disruption of operons and horizontal gene transfer are major contributions to the new, dynamic view of prokaryotic evolution. Under the 'selfish operon' hypothesis, operons are viewed as mobile genetic entities that are constantly disseminated via horizontal gene transfer, although their retention could be favored by the advantage of coregulation of functionally linked genes." https://lnkd.in/eRYS-TZ View in LinkedIn

"HORIZONTAL GENE TRANSFER (HGT) is thought to play an important role in the evolution of species and innovation of genomes. Here, we present a method of identifying HGT events within a given protein family and estimate the global extent of HGT in all curated protein domain families (≈8,000) listed in the Pfam database." https://lnkd.in/eawF3Dn View in LinkedIn
