Looking across the gap: Understanding the evolution of eyes and vision among insects

BioEssays, Volume 46, Issue 5, May 2024.
The graphical abstract illustrates research on insectcompound eyes that have recently made important contributions tounderstanding their evolution, development and function across species.Evolutionary changes in the regulation of compound eye development andthe underlying neural networks resulting in differences in eye structureand how information is ...

Inferring the history of speciation from multilocus DNA sequence data: the case of Drosophila pseudoobscura and close relatives.

Molecular biology and evolution, 2002
The divergence of Drosophila pseudoobscura from its close relatives, D. persimilis and D. pseudoobscura bogotana, was examined using the pattern of DNA sequence variation in a common set of 50 inbred lines at 11 loci from diverse locations in the genome.

Dysfunction of Drosophila mitochondrial carrier homolog (Mtch) alters apoptosis and disturbs development

FEBS Open Bio, Volume 14, Issue 2, Page 276-289, February 2024.
Mitochondrial carrier homologs 1 (MTCH1) and 2 (MTCH2) are outer mitochondrial membrane translocases related to inner membrane carriers. In humans, MTCH1 interacts with presenilin 1 and induces apoptosis upon overexpression. We show here that the Drosophila ortholog is required for development, inducing apoptosis upon its downregulation both in the ...

Conserved genomic organisation of Group B Sox genes in insects.

BMC Genetics, 2005
Background Sox domain containing genes are important metazoan transcriptional regulators implicated in a wide rage of developmental processes. The vertebrate B subgroup contains the Sox1, Sox2 and Sox3 genes that have early functions in neural ...

Chromosome-Level Assembly of Drosophila bifasciata Reveals Important Karyotypic Transition of the X Chromosome

G3: Genes, Genomes, Genetics, 2020
The Drosophila obscura species group is one of the most studied clades of Drosophila and harbors multiple distinct karyotypes. Here we present a de novo genome assembly and annotation of D. bifasciata, a species which represents an important subgroup for

Sexual selection and experimental evolution of chemical signals in Drosophila pseudoobscura

Journal of Evolutionary Biology, 2012
Our expectations for the evolution of chemical signals in response to sexual selection are uncertain. How are chemical signals elaborated? Does sexual selection result in complexity of the composition or in altered quantities of expression?

The heritability of mating behaviour in a fly and its plasticity in response to the threat of sperm competition.

PLoS ONE, 2014
Phenotypic plasticity is a key mechanism by which animals can cope with rapidly changeable environments, but the evolutionary lability of such plasticity remains unclear.

Drosophila Sexual Attractiveness in Older Males Is Mediated by Their Microbiota

Microorganisms, 2020
Age is well known to be a basis for female preference of males. However, the mechanisms underlying age-based choices are not well understood, with several competing theories and little consensus.

Genetic Architecture of Male Sterility and Segregation Distortion in Drosophila pseudoobscura Bogota–USA Hybrids

Genetics, 2011
Understanding the genetic basis of reproductive isolation between recently diverged species is a central problem in evolutionary genetics. Here, I present analyses of the genetic architecture underlying hybrid male sterility and segregation distortion ...

Epistasis among Drosophila persimilis factors conferring hybrid male sterility with D. pseudoobscura bogotana. [PDF]

PLoS ONE, 2010
The Bateson-Dobzhansky-Muller model posits that hybrid incompatibilities result from genetic changes that accumulate during population divergence.
