Genome Sequence of the Pea Aphid Acyrthosiphon pisum
The genome of the pea aphid shows remarkable levels of gene duplication and equally remarkable gene absences that shed light on aspects of aphid biology, most especially its symbiosis with Buchnera.
The evolutionary history of termites as inferred from 66 mitochondrial genomes.
The inference of ancestral geographic ranges shows that the Termitidae, which includes more than 75% of extant termite species, most likely originated in Africa or Asia, and acquired their pantropical distribution after a series of dispersal and subsequent diversification events.

The pea aphid is a useful model system for examining how a single genome has evolved to allow divergent modes of development and the function of the serosa has diverged greatly in the two embryos.

It is suggested that, following the reception of kairomone signals, the identified genes are involved in a series of defensive phenotypic alterations and the production of a defensive phenotype.

The development and evolution of aphid bacteriocytes, the host cells that contain the endosymbiotic bacteria Buchnera aphidicola, are studied and it is experimentally demonstrated that bacteriocyte induction and proliferation occur independently of B. aphidICola.
Extremotolerant tardigrade genome and improved radiotolerance of human cultured cells by tardigrade-unique protein
Using human cultured cells, it is demonstrated that a tardigrade-unique DNA-associating protein suppresses X-ray-induced DNA damage by ∼40% and improves radiotolerance, indicating the relevance of tardigrate-unique proteins to tolerability and tardigades could be a bountiful source of new protection genes and mechanisms.
Developmental Link between Sex and Nutrition; doublesex Regulates Sex-Specific Mandible Growth via Juvenile Hormone Signaling in Stag Beetles
This study is the first to demonstrate a causal link between the sex determination and JH signaling pathways, which clearly interact to determine the developmental fates and final sizes of nutrition-dependent secondary-sexual characters.
Comprehensive survey of developmental genes in the pea aphid, Acyrthosiphon pisum: frequent lineage‐specific duplications and losses of developmental genes
It is found that most developmental genes were well conserved in the pea aphid, although many lineage‐specific gene duplications and gene losses have occurred in several gene families.
Molecular phylogeny of the Rhinotermitidae
A number of disagreements were found between the molecular tree and traditional classifications of genera within subfamilies among the termite family Rhinotermitidae, however relationships were not well defined.
