SINGLE CLONAL FARMS. "Ants farm subterranean aphids...had considerable clonal diversity at the population level. Yet more than half of the ant mounds contained just a single aphid species, a significantly higher percentage than expected from a random distribution. Over 60% of these single-species mounds had a single aphid clone, and clones tended to persist across subsequent years." https://lnkd.in/dShsfQM View in LinkedIn

PREFERENTIAL. “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.” (lincRNA = Long intergenic non-coding RNA); (TE = transposable elements). https://lnkd.in/dwuaM5f View in LinkedIn

BACTERIAL VOLATILES. "Honeydew volatiles, mostly from bacterial origins, are known to be a key element in ant attraction...The relative attractiveness of volatiles emitted by honeydews collected from each aphid species and by bacteria isolated from each honeydew was in investigated. Again, ants significantly preferred volatiles released by Aphis fabae honeydew and bacteria. This information suggests that microbial honeydew volatiles enable ants to distantly discriminate aphid species." https://lnkd.in/dA6GrhP View in LinkedIn

SKEW. “The content of TES in lincRNA genes is substantially higher than that in protein-coding genes, especially in exons and promoter regions.” (lincRNA = Long intergenic non-coding RNA); (TE = transposable elements); (TE = transposable elements). https://lnkd.in/dwuaM5f View in LinkedIn

THREE-WAY. "Niphanda fusca butterflies lay eggs on plants where ants tend herds of aphids. The eggs hatch as caterpillars which feed on the aphids. The ants do not defend the aphids from the caterpillars (this is due to the caterpillar producing a pheromone the ants detect making them think the caterpillar is actually one of them), but carry the caterpillars to their nest. In the nest, the ants feed the caterpillars, who in return produce honeydew for the ants." https://lnkd.in/dTDsdH3 View in LinkedIn

THE SPLIT. “Higher frequencies of ancient TEs in promoters and exons compared to introns implies that many lincRNA genes emerged before the split of primates and rodents.” (TE = transposable elements). https://lnkd.in/dwuaM5f View in LinkedIn

VIRAL CONTRIBUTION. “The TEs are the primary contributors to the bulk of the genomic DNA in many eukaryotes, in particular mammals, and have the potential to contribute to the evolution of the hosts by providing novel regulatory or coding sequences.” (TE = transposable elements). https://lnkd.in/dwuaM5f View in LinkedIn

FAMILY OF FOSSILS. “Retrotransposons including long interspersed repetitive elements (LINEs), short interspersed repetitive elements (SINEs), and long terminal repeat (LTR) retrotransposons are widely represented in mammals.” https://lnkd.in/dwuaM5f View in LinkedIn

ABUNDANT VIRAL FOSSILS. “Diverse TEs are widespread and abundant in the genomes of most eukaryotes. Different classes of TEs include mobile retrovirus-like elements, or retrotransposons, which transpose within the genome via RNA intermediates, and DNA transposons, which can relocate directly.” (TE = transposable elements). https://lnkd.in/dwuaM5f View in LinkedIn

PIVOTAL. “The discovery of the pivotal contribution of TEs to the evolution of the Xist gene prompts the question on a possible general role of TEs in the evolution of lincRNAs.” (lincRNA = long intergenic non-coding RNA; TE = transposable elements; Xist = (X-inactive specific transcript) is an RNA gene on the X chromosome of the placental mammals). https://lnkd.in/dwuaM5f View in LinkedIn
