Data from: Allatostatin A signalling in Drosophila regulates feeding and sleep and is modulated by PDF

Feeding and sleep are fundamental behaviours with significant interconnections and cross-modulations. The circadian system and peptidergic signals are important components of this modulation, but still little is known about the mechanisms and networks by which they interact to regulate feeding and sleep. We show that specific thermogenetic activation of peptidergic Allatostatin A (AstA)-expressing PLP neurons and enteroendocrine cells reduces feeding and promotes sleep in the fruit fly Drosophila. The effects of AstA cell activation are...

Data from: Caspr3-deficient mice exhibit low motor learning during the early phase of the accelerated rotarod task

Haruna Hirata, Aki Takahashi, Yasushi Shimoda & Tsuyoshi Koide
Caspr3 (Contactin-associated protein-like 3, Cntnap3) is a neural cell adhesion molecule belonging to the Caspr family. We have recently shown that Caspr3 is expressed abundantly between the first and second postnatal weeks in the mouse basal ganglia, including the striatum, external segment of the globus pallidus, subthalamic nucleus, and substantia nigra. However, its physiological role remains largely unknown. In this study, we conducted a series of behavioral analyses on Capsr3-knockout (KO) mice and equivalent wild-type...

Data from: A linkage map and QTL analysis for pyrethroid resistance in the bed bug Cimex lectularius

Toby Fountain, Mark Ravinet, Richard Naylor, Klaus Reinhardt & Roger K. Butlin
The rapid evolution of insecticide resistance remains one of the biggest challenges in the control of medically and economically important pests. Insects have evolved a diverse range of mechanisms to reduce the efficacy of the commonly used classes of insecticides and finding the genetic basis of resistance is a major aid to management. In a previously unstudied population, we performed an F2 resistance mapping cross for the common bed bug, Cimex lectularius, for which insecticide...

Data from: Different contributions of local- and distant-regulatory changes to transcriptome divergence between stickleback ecotypes

Asano Ishikawa, Makoto Kusakabe, Kohta Yoshida, Mark Ravinet, Takashi Makino, Atsushi Toyoda, Asao Fujiyama & Jun Kitano
Differential gene expression can play an important role in phenotypic evolution and divergent adaptation. Although differential gene expression can be caused by both local- and distant-regulatory changes, we know little about their relative contribution to transcriptome evolution in natural populations. Here, we conducted expression quantitative trait loci (eQTL) analysis to investigate the genetic architecture underlying transcriptome divergence between marine and stream ecotypes of threespine sticklebacks (Gasterosteus aculeatus). We identified both local and distant eQTLs, some...

Data from: Impact of cryptic female choice on insemination success: larger sized and longer copulating male squid ejaculate more, but females influence insemination success by removing spermatangia

Noriyosi Sato, Masaaki Yoshida, Takashi Kasugai & Masa-Aki Yoshida
In polyandrous mating systems, sperm competition and cryptic female choice (CFC) are well recognized as postcopulatory evolutionary forces. However, it remains challenging to separate CFC from sperm competition and to estimate how much CFC influences insemination success because those processes usually occur inside the female's body. The Japanese pygmy squid, Idiosepius paradoxus, is an ideal species in which to separate CFC from sperm competition because sperm transfer by the male and sperm displacement by the...

Data from: Genetic basis for variation in salinity tolerance between stickleback ecotypes

Makoto Kusakabe, Asano Ishikawa, Mark Ravinet, Kohta Yoshida, Takashi Makino, Atsushi Toyoda, Asao Fujiyama & Jun Kitano
Adaptation to different salinities can drive and maintain divergence between populations of aquatic organisms. Anadromous and stream ecotypes of threespine stickleback (Gasterosteus aculeatus) are an excellent model to explore the genetic mechanisms underlying osmoregulation divergence. Using a parapatric pair of anadromous and stream stickleback ecotypes, we employed an integrated genomic approach to identify candidate genes important for adaptation to different salinity environments. Quantitative trait loci (QTL) mapping of plasma sodium concentrations under a seawater challenge...
