Sex determination gene Doublesex in hemimetabolous insects

open access: yesCurrent 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.

Sexual dimorphism of sleep regulated by juvenile hormone signaling in Drosophila. [PDF]

open access: yesPLoS Genetics, 2018
Sexually dimorphic phenotypes are a universal phenomenon in animals. In the model animal fruit fly Drosophila, males and females exhibit long- and short-sleep phenotypes, respectively. However, the mechanism is still a mystery.

Prospects of multipurpose biomonitoring for fisheries assessment based on environmental nucleic acids

open access: yesJournal of Fish Biology, EarlyView.
Abstract Methods using environmental nucleic acids have become highly effective for monitoring aquatic biodiversity, with an array of suitable use cases, including metrics for fisheries assessment. Traditional methods for assessing fish populations often rely on invasive techniques with limited spatial and temporal coverage.

The Evolution of Mimicry; The Doublesex Gene

open access: yes, 2021
Many butterfly species use mimicry in order to increase their chance of survival. In Batesian mimicry, non toxic butterflies mimic the wing patterns, colors, and shapes of another species that is toxic to predators.

Sex Determination in Sponges

open access: yesMolecular Reproduction and Development, Volume 93, Issue 6, June 2026.
ABSTRACT Sex determination in Porifera remains one of the least understood aspects of early metazoan biology despite the group's key phylogenetic position. Sponges display exceptional diversity in sexual systems—ranging from stable gonochorism to sequential hermaphroditism and sex reversal—yet lack morphological dimorphism and any discrete gonadal ...

Identification of sex-specific transcripts of theAnopheles gambiae doublesexgene [PDF]

open access: yesJournal of Experimental Biology, 2005
SUMMARYThe understanding of the molecular mechanisms of sex differentiation in the mosquito Anopheles gambiae could identify important candidate genes for inducing selective male sterility in transgenic lines or for sex-controlled expression of lethal genes.

Alternative splicing regulation of doublesex gene by RNA-binding proteins in the silkworm Bombyx mori

open access: yes, 2019
Doublesex is highly conserved and sex-specifically spliced in insect sex-determination pathways, and its alternative splicing (AS) is regulated by Transformer, an exonic splicing activator, in the model system of Drosophila melanogaster.

Monitoring African Megafauna in an Anthropogenic Landscape: A 15‐Year Case Study of the Vulnerable West African Giraffe

open access: yesAnimal Conservation, Volume 29, Issue 3, Page 235-248, June 2026.
We used pattern recognition software to correct misidentifications in a 15‐year photographic database of the last, vulnerable West African giraffe population in Niger. After revealing substantial methodological errors that had inflated population estimates by nearly 19%, we corrected individual encounter histories and applied capture‐mark‐recapture ...

Integrative Advances in Equine Genomics From Reference Assemblies to Evolutionary History and Key Traits

open access: yesEvolutionary Applications, Volume 19, Issue 6, June 2026.
ABSTRACT Horses are major domestic animals and cultural symbols that have accompanied humans for millennia. They underpin transport, agriculture, warfare and sport, and also provide a model for studying domestication, complex traits and adaptive evolution.

Serotonergic neuronal death and concomitant serotonin deficiency curb copulation ability of Drosophila platonic mutants

open access: yesNature Communications, 2016
Drosophila platonic (plt) mutant males court with females but fail to copulate. Here, the authors find plt is an allele of scribblerand may disrupt courtship behaviour via developmental disruption of a subgroup of serotonergic Doublesex+ neurons in the ...
