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

PLoS 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).

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

PLoS 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]

PLoS 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

IEEE 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]

PLoS 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.

Ancestral polymorphisms explain the role of chromosomal inversions in speciation. [PDF]

PLoS Genetics, 2018
Understanding the role of chromosomal inversions in speciation is a fundamental problem in evolutionary genetics. Here, we perform a comprehensive reconstruction of the evolutionary histories of the chromosomal inversions in Drosophila persimilis and D ...

Large introns in relation to alternative splicing and gene evolution: a case study of Drosophila bruno-3 [PDF]

, 2009
Background: Alternative splicing (AS) of maturing mRNA can generate structurally and functionally distinct transcripts from the same gene. Recent bioinformatic analyses of available genome databases inferred a positive correlation between intron length ...

How chromosomal inversions reorient the evolutionary process

Journal 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.

De novo transcriptome assembly reveals sex-specific selection acting on evolving neo-sex chromosomes in Drosophila miranda. [PDF]

, 2014
BackgroundThe Drosophila miranda neo-sex chromosome system is a useful resource for studying recently evolved sex chromosomes. However, the neo-Y genomic assembly is fragmented due to the accumulation of repetitive sequence.

SELECTION BY FERTILITY IN DROSOPHILA PSEUDOOBSCURA [PDF]

Genetics, 1974
ABSTRACT Fertility, the component of selection due to female fecundity and male mating success, differed significantly among the ST/ST, ST/AR, and AR/AR karyotypes in experimental populations and varied with karyotypic frequency. In relation to ST/AR, ST/ST females and males had higher fertilities at low frequency; AR/AR males and ...
