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.
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.
A mutation in the receptor Methoprene-tolerant alters juvenile hormone response in insects and crustaceans.
TLDR
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.
Sexually Dimorphic Body Color Is Regulated by Sex-Specific Expression of Yellow Gene in Ponerine Ant, Diacamma Sp
TLDR
It was concluded that transcriptional regulation of yellow was responsible for the sexual color dimorphism observed in this species.
RNA-seq analysis of the gonadal transcriptome during Alligator mississippiensis temperature-dependent sex determination and differentiation
TLDR
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.
Ionotropic Glutamate Receptors Mediate Inducible Defense in the Water Flea Daphnia pulex
TLDR
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.
Molecular cloning of doublesex genes of four cladocera (water flea) species
TLDR
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.
Comparison of JH signaling in insects and crustaceans.
Neofunctionalization of Androgen Receptor by Gain-of-Function Mutations in Teleost Fish Lineage.
TLDR
Findings together indicate that the substitutions generating a new functionality of teleost ARα were fixed in teleost genome after the divergence of the Elopomorpha lineage, and provide a molecular explanation for an adaptation process leading to generation of the hyperactive AR subtype after TSGD.
NMDA receptor activation upstream of methyl farnesoate signaling for short day-induced male offspring production in the water flea, Daphnia pulex
TLDR
It is demonstrated that de novo methyl farnesoate (MF) synthesis is necessary for male offspring production and the key role of innate MF signaling as a conductor between external environmental stimuli and the endogenous male developmental pathway is indicated.
