TL;DR: Psyllids, whiteflies, aphids, and mealybugs are members of the suborder Sternorrhyncha and share a common property, namely the utilization of plant sap as their food source, and the different properties of the genomes and fragments of the genome suggest that there are different constraints on the permissible evolutionary changes.

TL;DR: Rates calibrated using dates inferred from fossil aphids imply that Asian and American species of the aphid tribe Melaphidina diverged by the early Eocene; this result confirms an earlier hypothesis based on biogeographic evidence.

TL;DR: Genetic and physiological studies indicate that Buchnera can synthesize methionine, cysteine, and tryptophan and supply these amino acids to the aphid host and involve plasmid-amplification of the gene coding for anthranilate synthase, the first enzyme of the tryptophile biosynthetic pathway.

TL;DR: One hundred and seventy-three strains of marine, luminous bacteria isolated from sea water, surfaces and intestines of fish, as well as from the luminous organs of fish and squid were submitted to an extensive phenotypic characterization as discussed by the authors.

TL;DR: These findings suggest that this endocytobiotic association was established in a common ancestor of the four aphid families with subsequent diversification into the present species of aphids and their endosymbionts.
