Layered roles of fruitless isoforms in specification and function of male aggression-promoting neurons in Drosophila

eLife, 2020
Inter-male aggressive behavior is a prominent sexually dimorphic behavior. Neural circuits that underlie aggressive behavior are therefore likely under the control of sex-determining genes.

Sex-determining genes distinctly regulate courtship capability and target preference via sexually dimorphic neurons

eLife, 2020
For successful mating, a male animal must execute effective courtship behaviors toward a receptive target sex, which is female. Whether the courtship execution capability and upregulation of courtship toward females are specified through separable sex ...

Non-coding changes cause sex-specific wing size differences between closely related species of Nasonia. [PDF]

PLoS Genetics, 2010
The genetic basis of morphological differences among species is still poorly understood. We investigated the genetic basis of sex-specific differences in wing size between two closely related species of Nasonia by positional cloning a major male-specific

Doublesex and the Regulation of Sexual Dimorphism in Drosophila melanogaster [PDF]

Journal of Biological Chemistry, 2008
Drosophila yolk protein genes are regulated by doublesex male protein (DSXM) in males and doublesex female protein (DSXF) in females. Both proteins bind to the same DNA sites from which DSXM represses and DSXF activates transcription. The proteins are identical through 397 NH2-terminal amino acids that include domains for oligomerization and DNA ...

Downregulation of female doublesex expression by oral-mediated RNA interference reduces number and fitness of Anopheles gambiae adult females

Parasites & Vectors, 2019
Background Mosquito-borne diseases affect millions worldwide, with malaria alone killing over 400 thousand people per year and affecting hundreds of millions.

A male-specific doublesex isoform reveals an evolutionary pathway of sexual development via distinct alternative splicing mechanisms

Communications Biology, 2022
An ancestral male-specific doublesex isoform, dsxM2, is identified via intron retention, with a masculinizing function weaker than the modern ...

Oviposition but not sex allocation is associated with transcriptomic changes in females of the parasitoid wasp Nasonia vitripennis [PDF]

, 2015
This work was supported by Natural Environment Research Council (NERC) grant (NE/J024481/1). DMS was previously funded by a NERC Advanced Research Fellowship.Linking the evolution of the phenotype to the underlying genotype is a key aim of evolutionary ...

Characterization of the First W-Specific Protein-Coding Gene for Sex Identification in Helicoverpa armigera

Frontiers in Genetics, 2020
Helicoverpa armigera is a globally-important crop pest with a WZ (female)/ZZ (male) sex chromosome system. The absence of discernible sexual dimorphism in its egg and larval stages makes it impossible to address any sex-related theoretical and applied ...

Molecular characterization and functional analysis of DMRT11E in black tiger shrimp (Penaeus monodon)

Aquaculture Reports, 2022
As a highly conserved transcription factor family, DMRTs (Doublesex and Mab-3-related transcription factors) are involved in sex determination and sexual differentiation in numerous animals.
