Neural circuitry coordinating male copulation

open access: yeseLife, 2016
Copulation is the goal of the courtship process, crucial to reproductive success and evolutionary fitness. Identifying the circuitry underlying copulation is a necessary step towards understanding universal principles of circuit operation, and how ...

Tracing the origin and evolution of supergene mimicry in butterflies

open access: yesNature Communications, 2017
Wing pattern mimicry in the butterfly Papilio polytes is controlled by a single Mendelian locus, the mimicry supergene doublesex. Here, Zhang and colleagues reconstruct the complex evolutionary history of the doublesex supergene and mimicry in the ...

Hemimetabolous insects elucidate the origin of sexual development via alternative splicing

open access: yeseLife, 2019
Insects are the only known animals in which sexual differentiation is controlled by sex-specific splicing. The doublesex transcription factor produces distinct male and female isoforms, which are both essential for sex-specific development.

Characterization of sex-specific variants of doublesex and feminizer genes in stingless bee species

open access: yes, 2020
International audienceAbstractSex determination is one of the major developmental events in higher metazoans, where complex molecular mechanisms define two physiologically and behaviorally distinct organisms still genetically compatible.

Sex Differences in Drosophila Somatic Gene Expression: Variation and Regulation by doublesex

open access: yesG3: Genes, Genomes, Genetics, 2016
Sex differences in gene expression have been widely studied in Drosophila melanogaster. Sex differences vary across strains, but many molecular studies focus on only a single strain, or on genes that show sexually dimorphic expression in many strains ...

Integrative analysis reveals pathways associated with sex reversal in Cynoglossus semilaevis [PDF]

open access: yesPeerJ, 2020
Sex reversal is a complex biological phenomenon exhibited by Cynoglossus semilaevis. Some genetic females may irreversibly convert to pseudomales, thus increasing aquaculture costs because males grow much more slowly than females.

Identification and characterization of doublesex from the pumpkin fruit fly, Bactrocera tau (Diptera: Tephritidae)

open access: yesEuropean Journal of Entomology, 2018
The sex determination cascades in insects are diversified at the top of the cascade, where different primary molecular signals are employed, while at the bottom of the cascades, particularly the doublesex genes, are highly conserved.

The neural basis for a persistent internal state in Drosophila females

open access: yeseLife, 2020
Sustained changes in mood or action require persistent changes in neural activity, but it has been difficult to identify the neural circuit mechanisms that underlie persistent activity and contribute to long-lasting changes in behavior.

Genome-wide identification and comparative analysis of Dmrt genes in echinoderms

open access: yesScientific Reports, 2023
The Dmrt (Doublesex-mab3-related transcription factor) gene family is a class of crucial transcription factors characterized by one or several conserved DM (Doublesex/Mab-3) domains.

A shared genetic basis of mimicry across swallowtail butterflies points to ancestral co-option of doublesex

open access: yesNature Communications, 2020
Polymorphic mimicry in Papilio swallowtail butterflies is thought to have had multiple independent origins. Here, the authors show that the gene doublesex controls mimicry across multiple species, but with distinct alleles that may have originated from ...
