HOT SPOT. "Dense microbial communities, such as the human gut microbiota are now considered a hot spot of microbial gene transfer. This is all the more interesting since it was recently discovered that the rate of HGT is apparently eight to nine orders of magnitude faster than previously thought." (HGT = horizontal gene transfer). https://lnkd.in/e5FE9cJ View in LinkedIn

TROJAN HORSES. "Viruses have insinuated themselves into the genome of our ancestors for hundreds of millions of years. They typically have gotten there by infecting eggs or sperm, inserting their own DNA into ours. There are 100,000 known fragments of viruses in the human genome, making up over 8% of our DNA." https://lnkd.in/eFhFQjd View in LinkedIn

COMPLEX NETWORK. "Virophages, polintons, and transpovirons: a complex evolutionary network of diverse selfish genetic elements with different reproduction strategies. Recent advances of genomics and metagenomics reveal remarkable diversity of viruses and other selfish genetic elements." https://lnkd.in/eEUzxrC View in LinkedIn

BIOINFORMATICS POWER. "Metagenomic sequences are a treasure trove of novel genes and genomes. The rapidly growing metagenomic databases provide increasing opportunities for computational discovery of new groups of organisms. Identification of new viruses is particularly straightforward given the comparatively small size of viral genomes, although fast evolution of viruses complicates the analysis of novel sequences." https://lnkd.in/erZCmAF View in LinkedIn

THE MISSING LINK. "The line between viruses and parasitic elements of the genome is thin and delicate, and probably often crossed. Parasitic elements that acquire the means to escape the host cell become viruses and, conversely, viruses can lose this ability and return to a more limited lifestyle as transposable elements (TEs)." https://lnkd.in/eGu7jnP View in LinkedIn
