Masculinizer and Doublesex as Key Factors Regulate Sexual Dimorphism in Ostrinia furnacalis

Cells, 2022
SIMPLE SUMMARY: In animals, sexually dimorphic traits are ubiquitous and play vital roles in reproduction, courtship, and environmental adaptation, especially in insects.

doublesex is a mimicry supergene

Nature, 2014
One of the most striking examples of sexual dimorphism is sex-limited mimicry in butterflies, a phenomenon in which one sex--usually the female--mimics a toxic model species, whereas the other sex displays a different wing pattern. Sex-limited mimicry is phylogenetically widespread in the swallowtail butterfly genus Papilio, in which it is often ...

A Positive Role in Differentiation for the Male doublesex Protein of Drosophila

Developmental Biology, 1993
The doublesex (dsx) locus encodes male-specific and female-specific polypeptides that are essential for the proper differentiation of sexually dimorphic somatic features of Drosophila melanogaster. Ectopic expression of the male-specific dsx polypeptide was obtained by P-element-mediated transformation of flies with a construct bearing a fusion between

Doublesex in the Middle

Science, 2002
What are the molecular mechanisms that determine the acquisition of male and female sexual characteristics? In a Perspective, Ken Burtis reviews a series of recent papers published elsewhere that elucidate the part played by the transcription factor, doublesex, in determining sexual dimorphism in the fruit fly.

Analysis of the biological functions of a doublesex homologue in Bombyx mori

Development Genes and Evolution, 2003
We have previously reported that Bmdsx, a homologue of the sex-determining gene doublesex ( dsx), was sex-specifically expressed in various tissues of the silkworm. The primary transcript of Bmdsx is alternatively spliced in males and females to yield sex-specific mRNAs that encode male-specific (BmDSXM) and female-specific (BmDSXF) polypeptides.

Identification and characterization of doublesex in Bemisia tabaci

Insect Molecular Biology, 2018
Abstract Bemisia tabaci (Gennadius) is an important agricultural pest with a worldwide distribution. Although B. tabaci is known to have a unique haplodiploid reproductive strategy, its sex determination mechanism is largely unknown.

Doublesex is essential for masculinization but not feminization in Lygus hesperus

Insect Biochemistry and Molecular Biology
In most holometabolous insects, sex differentiation occurs via a hierarchical cascade of transcription factors, with doublesex (dsx) regulating genes that control sex-specific traits. Although less is known in hemimetabolous insects, early evidence suggests that substantial differences exist from more evolutionarily advanced insects.

DOUBLESEX GENE EXPRESSION IN THE CENTRAL NERVOUS SYSTEM OF DROSOPHILA MELANOGASTER

Journal of Neurogenetics, 2002
Despite several behavior-genetic studies that have suggested roles played by doublesex (dsx) in neural tissues, it has not been demonstrated that the products of this gene are actually present in the central nervous system (CNS). In this report, we describe the cellular, spatial, and temporal expression patterns of dsx gene products in the developing ...

The Roles of Fruitless and Doublesex in the Control of Male Courtship

2011
Male courtship in Drosophila melanogaster is a robust innate behavior that is shaped by sensory input and experience. It is regulated by the general sex-determination pathway through the sex-specific forms of fruitless and doublesex. Recent findings have shown that both fruitless and doublesex are required for courtship.

Alternative splicing patterns of doublesex reveal a missing link between Nix and doublesex in the sex determination cascade of Aedes albopictus

Insect Science, 2020
AbstractSexual development in insects is regulated by a complicated hierarchical cascade of sex determination. The primary signals are diverse, whereas the central nexus doublesex (dsx) gene is relatively conserved within the pathway. Aedes (Stegomyia) albopictus is an important vector with an extensive worldwide distribution.
