APHID MICROBIOTA. "The microbiota of most aphids is dominated by the γ-proteobacterium Buchnera aphidicola, which provides the aphid with essential amino acids and is required by the insect: aphids experimentally deprived of B. aphidicola by antibiotic treatment (‘aposymbiotic’ aphids) grow very slowly and are reproductively sterile." http://rspb.royalsocietypublishing.org/content/275/1634/565.short View in LinkedIn

POOR DIET. "Plant phloem sap is one diet with a grossly unbalanced amino acid composition. Symbiotic bacteria enable insect to use a nutritionally inadequate diet. The capacity of aphids to use plant phloem sap, with low essential amino acid content, has been attributed to their symbiotic bacteria, Buchnera aphidicola, which can synthesize these nutrients." https://lnkd.in/d5SK36b View in LinkedIn

SUPPLEMENTAL DIET. "Many herbivorous insects are chronically infected by symbiotic micro-organisms, some of which supplement the nutritionally poor plant diet with vitamins and essential amino acids. These symbiotic micro-organisms are generally beneficial for the insect host." https://lnkd.in/dNuJ26a View in LinkedIn

SURPRISE. “Strikingly, the total number of genes for ncRNAs that are expressed from a mammalian genome seems to exceed the number of protein-coding genes several fold.” (ncRNA = non-coding RNA). https://lnkd.in/dwuaM5f View in LinkedIn

INSECTS. "It is roughly estimated that more than 70% of species host one or more bacterial symbionts." https://lnkd.in/dapi6EP View in LinkedIn

FAST DIVERSIFICATION. “These results are consistent with the repeat insertion domains of LncRNAs hypothesis under which TEs have substantially contributed to the origin, evolution, and, in particular, fast functional diversification, of lincRNA genes.” (lincRNA = Long intergenic non-coding RNA); (TE = transposable elements). https://lnkd.in/dwuaM5f View in LinkedIn

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
