FAST-TRACK PREFERENCE. "A significant positive correlation was detected between the content of TEs and evolutionary rate of lincRNAs indicating that inserted TEs are preferentially fixed in fast-evolving lincRNA genes." (TE = transposable elements; LincRNA= long intergenic non-coding RNA). https://lnkd.in/dwuaM5f View in LinkedIn

“THE STAGGERING evolutionary success of TEs in eukaryotes is often attributed to their ability to out replicate the host genomes in which they reside, as opposed to any selective advantage that they might provide to their hosts.” (TE = transposable elements). https://lnkd.in/dwuaM5f View in LinkedIn

WORTH THE PRICE. “It has been shown that TEs can spread within and among genomes even in the face of a selective cost to the host.” (TE = transposable elements). https://lnkd.in/dwuaM5f View in LinkedIn

“THE SELFISH DNA concept of TEs focuses on the parasitic nature of these elements and emphasizes the deleterious effects of transposition as well as the negligible evolutionary benefit that TEs provide to their hosts.” (TE = transposable elements). https://lnkd.in/dwuaM5f View in LinkedIn

“THE SHEER ABUNDANCE of TEs in the genome, as well as the variety of mutation effects induced by their mobility, suggest that they might, in some cases, be exapted or domesticated, to serve the evolutionary interests of the host.” (TE = transposable elements). https://lnkd.in/dwuaM5f View in LinkedIn

RESHAPING THE HOST GENOME. “Multiple lines of evidence indicate that the presence of TEs can result in host adaptation by shaping and reshaping the genome in many different ways.” (TE = transposable elements). https://lnkd.in/dwuaM5f View in LinkedIn

NEW VIEW OF GENOMES. “Traditionally, genomes have been perceived mostly as repositories of protein-coding genes. Although this might be largely true in the case of viruses, prokaryotes, and unicellular eukaryotes, numerous recent studies on the genomes of multicellular eukaryotes, particularly animals, have revealed a vast non-coding RNome, i.e., numerous genes encoding various classes of non-coding RNAs (ncRNAs).” https://lnkd.in/dwuaM5f View in LinkedIn

NON-CODING GENES AND VIRAL REMNANTS. “The TEs comprise at least half of the mammalian genomes, and in particular, are found in most lincRNAs.” (TE = transposable elements); (lincRNA = Long intergenic non-coding RNA). View in LinkedIn

FRAGMENT FROM NATURE deals with ant aphid farming. Ant societies are highly organized and have evolved many stunning food strategies, from cultivating fungal gardens to rearing aphids. This is a case study of mutualism between the ant and the aphid, where both parties gain from the relationship, although the relationship is more in favour of the ant. Enjoy the story that took millions of years to brew. View in LinkedIn

MUTUALISM OF ANTS AND APHIDS. "Social insects defend their own colonies and some species also protect their mutualist partners. In mutualisms with aphids, ants typically feed on honeydew produced by aphids and, in turn guard and shelter aphid colonies from insect natural enemies." https://lnkd.in/e6r3DvK View in LinkedIn
