Gene up-regulation in response to predator kairomones in the water flea, Daphnia pulex

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.

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.

A mutation in the receptor Methoprene-tolerant alters juvenile hormone response in insects and crustaceans.

It is shown that a single amino-acid substitution in the receptor Methoprene-tolerant has an important role during evolution of the arthropod juvenile hormone pathway.

RNA-seq analysis of the gonadal transcriptome during Alligator mississippiensis temperature-dependent sex determination and differentiation

Gonadal global gene expression kinetics during sex determination has been extensively profiled for the first time in a TSD species, and insights are provided into the genetic framework underlying TSD, and expand the current understanding of the developmental fate pathways during vertebrate sex determination.

Molecular cloning of doublesex genes of four cladocera (water flea) species

The all dsx genes of five cladoceran species examined had similar amino acid structure containing highly conserved DM and oligomerization domains, and exhibited sexually dimorphic expression patterns, suggesting that these genes may have similar functions for environmental sex determination incladocerans.

Roles of ecdysteroids for progression of reproductive cycle in the fresh water crustacean Daphnia magna

Cl cloning and phylogenetic analyses showed that nvd and shd as well as Cyp18a1 are evolutionary conserved in D. magna, suggesting that these genes appeared in arthropods before the radiation of insects.

Ionotropic Glutamate Receptors Mediate Inducible Defense in the Water Flea Daphnia pulex

These findings provide a candidate molecule required for the inducible defense response in D. pulex and will contribute to the understanding of complex mechanisms underlying the recognition of environmental changes, which form the basis of phenotypic plasticity.

Neverland regulates embryonic moltings through the regulation of ecdysteroid synthesis in the water flea Daphnia magna, and may thus act as a target for chemical disruption of molting

De novo ecdysteroid synthesis by nvd1 in the gut epithelial cells stimulates molting, which is indispensable for D. magna embryo development, and identifies neverland as a possible target for chemicals, including various pesticides that are known to disrupt molts, development and reproduction.
