Zinc finger binding motifs do not explain recombination rate variation within or between species of Drosophila. [PDF]

open access: yesPLoS ONE, 2012
In humans and mice, the Cys(2)His(2) zinc finger protein PRDM9 binds to a DNA sequence motif enriched in hotspots of recombination, possibly modifying nucleosomes, and recruiting recombination machinery to initiate Double Strand Breaks (DSBs).

Can patterns of chromosome inversions in Drosophila pseudoobscura predict polyandry across a geographical cline? [PDF]

open access: yesEcol Evol, 2014
Journal ArticleFemale multiple mating, known as polyandry, is ubiquitous and occurs in a wide variety of taxa. Polyandry varies greatly from species in which females mate with one or two males in their lifetime to species in which females may mate with ...

In vivo RNAi rescue in Drosophila melanogaster with genomic transgenes from Drosophila pseudoobscura. [PDF]

open access: yesPLoS ONE, 2010
BACKGROUND: Systematic, large-scale RNA interference (RNAi) approaches are very valuable to systematically investigate biological processes in cell culture or in tissues of organisms such as Drosophila.

Odorant receptor (Or) genes: polymorphism and divergence in the D. melanogaster and D. pseudoobscura lineages. [PDF]

open access: yesPLoS ONE, 2010
BACKGROUND: In insects, like in most invertebrates, olfaction is the principal sensory modality, which provides animals with essential information for survival and reproduction.

An Improved Method for Identification of Pre-miRNA in Drosophila

open access: yesIEEE Access, 2020
Identification of microRNAs is important in studies of regulation of gene expression in many biologyical processes. In this study, we developed an improved method for identification of microRNAs in Drosophila.

An investigation of Y chromosome incorporations in 400 species of Drosophila and related genera. [PDF]

open access: yesPLoS Genetics, 2018
Y chromosomes are widely believed to evolve from a normal autosome through a process of massive gene loss (with preservation of some male genes), shaped by sex-antagonistic selection and complemented by occasional gains of male-related genes.

How chromosomal inversions reorient the evolutionary process

open access: yesJournal of Evolutionary Biology, Volume 36, Issue 12, Page 1761-1782, December 2023., 2023
Inversions often play key roles in adaptation and speciation, but the processes that direct their evolution are obscured by the characteristic that makes them so unique (reduced recombination between arrangements). In this review, we examine how different mechanisms can impact inversion evolution, weaving together both theoretical and empirical studies.

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

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,
