Identification of the key stages for sex determination in the silkworm, Bombyx mori [PDF]

, 2013
In general, the master switch gene for sex determination is expressed for a limited period during the early embryonic stage. To increase our understanding of the sex determination mechanism in Bombyx mori, it is important to understand when sex ...

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

Advanced Functional Materials, EarlyView.
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.

Sex determination [PDF]

, 2012
Multicellular animals are a diverse lot, with widely varied body plans and lifestyles. One feature they share, however, is a nearly universal reliance on sexual reproduction for species propagation.

Rapid evolution of female-biased genes among four species of Anopheles malaria mosquitoes. [PDF]

, 2017
Understanding how phenotypic differences between males and females arise from the sex-biased expression of nearly identical genomes can reveal important insights into the biology and evolution of a species.

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-

The transformer gene controls sexual development in Drosophila suzukii

Insect Science, EarlyView.
The transformer gene plays a key role in the genetic pathway for sexual development in Drosophila suzukii Abstract The genetic network of sex determination in the model organism Drosophila melanogaster was investigated in great detail. Such knowledge not only advances our understanding of the evolution and regulation of sexual dimorphism in insects ...

Ochratoxin A: In Utero Exposure in Mice Induces Adducts in Testicular DNA [PDF]

, 2010
Ochratoxin A (OTA) is a nephrotoxin and carcinogen that is associated with Balkan endemic nephropathy and urinary tract tumors. OTA crosses the placenta and causes adducts in the liver and kidney DNA of newborns.

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

PLoS 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.

Genetic engineering for SIT application: a fruit fly‐focused review

Insect Science, EarlyView.
Abstract Sterile insect technique (SIT) has become a key component of efficient pest control. Fruit fly pests from the Drosophilidae and Tephritidae families pose a substantial and overwhelmingly increasing threat to the agricultural industry, aggravated by climate change and globalization among other contributors.
