A comparison of parthenogenetic and sexual embryogenesis of the pea aphid Acyrthosiphon pisum (Hemiptera: Aphidoidea).
TLDR
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. Expand
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.
TLDR
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. Expand
Gene up-regulation in response to predator kairomones in the water flea, Daphnia pulex
TLDR
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. Expand
Juvenile hormone titers and caste differentiation in the damp-wood termite Hodotermopsis sjostedti (Isoptera, Termopsidae).
TLDR
Results in both natural and artificial conditions show that the current model for JH action on termite caste differentiation is discussed and re-appraised, and JH titer was surprisingly low in neotenics. Expand
Extremotolerant tardigrade genome and improved radiotolerance of human cultured cells by tardigrade-unique protein
TLDR
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
TLDR
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. Expand
Comprehensive survey of developmental genes in the pea aphid, Acyrthosiphon pisum: frequent lineage‐specific duplications and losses of developmental genes
TLDR
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. Expand
Molecular phylogeny and biogeography of the nasute termite genus Nasutitermes (Isoptera: Termitidae) in the pacific tropics.
TLDR
The phylogenetic relationships among 17 Nasutitermes species from the Pacific tropics were inferred from sequences of mitochondrial cytochrome oxidase II and 16S ribosomal RNA genes, showing almost the same topology and in good agreement with reconstructions based on morphological or behavioral characters. Expand
Developmental Origin and Evolution of Bacteriocytes in the Aphid–Buchnera Symbiosis
TLDR
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. Expand
