Structure Formation in Butterfly Scales: Interplay of Genetic Control, Mechanical Instabilities, and Dynamic Material Properties

open access: yesAdvanced Functional Materials, Volume 36, Issue 38, 11 May 2026.
Butterfly wing scales are intricate cuticular functional nanosctructures. This perspective suggests that spatially varying material properties, cytoskeletal constraints, and growth‐driven mechanical instabilities shape the resulting nanoscale architectures created from single cells.

The Role of DNA Methylation and ZBTB Transcription Factors in Sex Differentiation, Maintenance and Heat‐Induced Masculinization in Zebrafish

open access: yesMolecular Reproduction and Development, Volume 93, Issue 5, May 2026.
ABSTRACT Sex differentiation, the process by which an organism develops as a male or female, can be influenced by the environment in many species. High temperature, or pollutant exposure, can lead to skewed sex‐ratios and genotype‐phenotype mismatches that can seriously threaten populations and biodiversity. Understanding the mechanisms involved in sex

Sex‐Specific Gene Expression Ontogeny During Gonadal Development in Post‐Metamorphic Xenopus tropicalis

open access: yesMolecular Reproduction and Development, Volume 93, Issue 4, April 2026.
Post‐metamorphic gonadal development in Xenopus tropicalis was analyzed through integrated morphometric, histological, and transcriptional approaches. Males showed upregulation of cyp17, amh, and amhr2, whereas females exhibited an increased aldh1a2 and ddx4.

Molecular cloning of doublesex genes of four cladocera (water flea) species [PDF]

open access: yes, 2013
The gene doublesex (dsx) is known as a key factor regulating genetic sex determination in many organisms. We previously identified two dsx genes (DapmaDsx1 and DapmaDsx2) from a freshwater branchiopod crustacean, Daphnia magna, which are expressed in ...

Neural-circuit basis of song preference learning in fruit flies

open access: yesiScience
Summary: As observed in human language learning and song learning in birds, the fruit fly Drosophila melanogaster changes its auditory behaviors according to prior sound experiences.

Genetic and neuronal mechanisms governing the sex-specific interaction between sleep and sexual behaviors in Drosophila

open access: yesNature Communications, 2017
Genes and circuits involved in sleep and sexual arousal have been extensively studied in Drosophila. Here the authors identify the sex determination genes fruitless and doublesex, and a sex-specific P1-DN1 neuronal feedback that governs the interaction ...

The gene transformer-2 of Anastrepha fruit flies (Diptera, Tephritidae) and its evolution in insects

open access: yesBMC Evolutionary Biology, 2010
Background In the tephritids Ceratitis, Bactrocera and Anastrepha, the gene transformer provides the memory device for sex determination via its auto-regulation; only in females is functional Tra protein produced.

Developmental genetic underpinnings of a symbiosis-associated organ in the fungus-farming ambrosia beetle Euwallacea validus

open access: yesScientific Reports, 2023
Mutualistic interactions between organisms often mediate the innovation of traits essential to maintain the relationship. Yet our understanding of these interactions has been stymied due to various hurdles in studying the genetics of non-model animals ...

The Doublesex Homolog Dmrt5 is Required for the Development of the Caudomedial Cerebral Cortex in Mammals [PDF]

open access: yesCerebral Cortex, 2012
Regional patterning of the cerebral cortex is initiated by morphogens secreted by patterning centers that establish graded expression of transcription factors within cortical progenitors. Here, we show that Dmrt5 is expressed in cortical progenitors in a high-caudomedial to low-rostrolateral gradient.
