An Unusual Role fordoublesexin Sex Determination in the DipteranSciara [PDF]

Genetics, 2015
AbstractThe gene doublesex, which is placed at the bottom of the sex-determination gene cascade, plays the ultimate discriminatory role for sex determination in insects. In all insects where this gene has been characterized, the dsx premessenger RNA (pre-mRNA) follows a sex-specific splicing pattern, producing male- and female-specific mRNAs encoding ...

Multiple Functions of the Dmrt Genes in the Development of the Central Nervous System

Frontiers in Neuroscience, 2021
The Dmrt genes encode the transcription factor containing the DM (doublesex and mab-3) domain, an intertwined zinc finger-like DNA binding module. While Dmrt genes are mainly involved in the sexual development of various species, recent studies have ...

Doublesex target genes in the red flour beetle, Tribolium castaneum [PDF]

Scientific Reports, 2012
Sex determination cascade in insects terminates with the production of sex-specific protein, Doublesex (Dsx). We identified the dsx homolog (Tcdsx) in Tribolium castaneum. The pre-mRNA of Tcdsx is sex-specifically spliced into three female (Tcdsxf1, Tcdsxf2 and Tcdsxf3) and one male-specific (Tcdsxm) isoforms.

Transcriptomics Unveil Dsx1 as a Critical Regulator in Sexual Dimorphism of Crustaceans

Integrative Zoology, EarlyView.
Sexually dimorphic traits are involved in reproductive competition and are shaped by sex‐biased gene expression. This study identifies Dsx1 as a key male‐biased gene in Morinoia aosen and demonstrates through RNA interference that its disruption feminizes male‐specific T3 leg structures.

Molecular mechanisms of sex determination in Lepidoptera: current status and perspectives. [PDF]

Insect Sci
The genetic basis of sex determination in Lepidoptera was discovered in 2014 in the silkworm Bombyx mori. In this model species, the W chromosome‐derived small piRNA called Fem piRNA downregulates the expression of a Z‐linked gene, Masculinizer (Masc), which leads to the default female‐specific splicing of the doublesex gene (dsxF) and thus to female ...

Sex peptide targets distinct higher order processing neurons in the brain to induce the female post-mating response

eLife
Sex peptide (SP) transferred during mating induces female post-mating responses including refractoriness to re-mate and increased oviposition in Drosophila. Yet, where SP-target neurons reside remained uncertain. Here, we show that expression of membrane-

Do Key Audit Matters in Hong Kong and Mainland China Provide Incremental Information and Improve Audit Quality? Les questions clés de l'audit à Hong Kong et en Chine continentale fournissent‐elles des renseignements supplémentaires et améliorent‐elles la qualité de l'audit?

Contemporary Accounting Research, EarlyView.
ABSTRACT We examine the adoption of expanded audit reports that include key audit matters (KAMs) in Hong Kong (2016) and mainland China (2017). These jurisdictions are highly integrated and together constitute one of the largest economies to adopt the IAASB's reporting standards in a staggered fashion, while also differing in investor protection and ...

Sex determination gene Doublesex in hemimetabolous insects

Current Opinion in Insect Science
Sexual differentiation is a fundamental process in animals, which, in insects, is dependent on sex determination gene cascades rather than sex hormones. Notably, gene transcriptional regulation by the sex-determining gene Doublesex (Dsx), which encodes a transcription factor, plays a pivotal role in sexual differentiation among different insect species.
