The females' response to male attractiveness: Mate choice, larvae production and differential brain protein expression

open access: yesEthology, Volume 129, Issue 10, Page 515-526, October 2023., 2023
Our study in Tenebrio molitor employed behavioral and proteomic analyses to establish a correlation between female mate choice and molecular changes in the female brain. We found that females preferred mating with more attractive males, who in turn had a greater likelihood of successfully mating and producing more larvae with attractive males than with

Functional Evolution of a cis-Regulatory Module [PDF]

open access: yes, 2005
Lack of knowledge about how regulatory regions evolve in relation to their structure–function may limit the utility of comparative sequence analysis in deciphering cis-regulatory sequences.

Meiotic transmission of Drosophila pseudoobscura chromosomal arrangements. [PDF]

open access: yesPLoS ONE, 2007
Drosophila pseudoobscura harbors a rich gene arrangement polymorphism on the third chromosome generated by a series of overlapping paracentric inversions.

Massive gene amplification on a recently formed Drosophila Y chromosome. [PDF]

open access: yes, 2019
Widespread loss of genes on the Y is considered a hallmark of sex chromosome differentiation. Here we show that the initial stages of Y evolution are driven by massive amplification of distinct classes of genes. The neo-Y chromosome of Drosophila miranda

Gene expression differentiation in the reproductive tissues of Drosophila willistoni subspecies and their hybrids

open access: yesMolecular Ecology, Volume 32, Issue 13, Page 3605-3623, July 2023., 2023
Abstract Early lineage diversification is central to understand what mutational events drive species divergence. Particularly, gene misregulation in interspecific hybrids can inform about what genes and pathways underlie hybrid dysfunction. In Drosophila hybrids, how regulatory evolution impacts different reproductive tissues remains understudied. Here,

The genomics of speciation in Drosophila: diversity, divergence, and introgression estimated using low-coverage genome sequencing.

open access: yesPLoS Genetics, 2009
In nature, closely related species may hybridize while still retaining their distinctive identities. Chromosomal regions that experience reduced recombination in hybrids, such as within inversions, have been hypothesized to contribute to the maintenance ...

Mistaken Identity: Another Bias in the Use of Relative Genetic Divergence Measures for Detecting Interspecies Introgression. [PDF]

open access: yesPLoS ONE, 2016
Measures of genetic divergence have long been used to identify evolutionary processes operating within and between species. However, recent reviews have described a bias in the use of relative divergence measures towards incorrectly identifying genomic ...

Identification of male- and female-specific olfaction genes in antennae of the oriental fruit fly (Bactrocera dorsalis) [PDF]

open access: yes, 2016
The oriental fruit fly (Bactrocera dorsalis) is a species of tephritid fruit fly, endemic to Southeast Asia but also introduced to many regions of the US, and it is one of the major pest species with a broad host range of cultivated and wild fruits ...

Multiple mating rescues offspring sex ratio but not productivity in a haplodiploid exposed to developmental heat stress

open access: yesFunctional Ecology, Volume 37, Issue 5, Page 1291-1303, May 2023., 2023
Read the free Plain Language Summary for this article on the Journal blog. Abstract Reproduction is generally more sensitive to high temperatures than survival and arguably a better predictor of the response of populations to climate change than survival estimates.

Sex-specific embryonic gene expression in species with newly evolved sex chromosomes. [PDF]

open access: yesPLoS Genetics, 2014
Sex chromosome dosage differences between females and males are a significant form of natural genetic variation in many species. Like many species with chromosomal sex determination, Drosophila females have two X chromosomes, while males have one X and ...
