A HOMOZYGOUS TRANSLOCATION IN DROSOPHILA MELANOGASTER [PDF]

open access: yesProceedings of the National Academy of Sciences, 1929
Five cases of translocation involving the third and the fourth chromosomes of Drosophila melanogaster have been found in the progeny of flies treated by x-rays. The flies carrying a given translocation seem to be perfectly normal in their appearance, but, when tested genetically, they show linkage of genes belonging to the third with genes belonging to

A comparative study of the short term cold resistance response in distantly related Drosophila species: the role of regucalcin and frost. [PDF]

open access: yesPLoS ONE, 2011
The molecular basis of short term cold resistance (indexed as chill-coma recovery time) has been mostly addressed in D. melanogaster, where candidate genes (Dca (also known as smp-30) and Frost (Fst)) have been identified.

Investigating Mitochondrial Gene Expression Patterns in Drosophila melanogaster Using Network Analysis to Understand Aging Mechanisms

open access: yesApplied Sciences, 2023
The process of aging is a complex phenomenon that involves a progressive decline in physiological functions required for survival and fertility. To better understand the mechanisms underlying this process, the scientific community has utilized several ...

Female remating in Drosophila ananassae: bidirectional selection for remating speed [PDF]

open access: yes, 2001
In Drosophila ananassae, artificial selection was carried out for fast and slow remating speed for 10 generations. Response to selection resulted in rapid divergence in remating time in each of two replicates of both fast and slow lines.

Effect of competitive cues on reproductive morphology and behavioral plasticity in male fruitflies [PDF]

open access: yes, 2015
Phenotypic plasticity will be favored whenever there are significant fitness benefits of responding to environmental variation. The extent and nature of the plasticity that evolves depends on the rate of environmental fluctuations and the capacity to ...

The Discovery, Distribution, and Evolution of Viruses Associated with Drosophila melanogaster.

open access: yesPLoS Biology, 2015
Drosophila melanogaster is a valuable invertebrate model for viral infection and antiviral immunity, and is a focus for studies of insect-virus coevolution. Here we use a metagenomic approach to identify more than 20 previously undetected RNA viruses and

The behavior of sympatric Chilean populations of Drosophila larvae during pupation

open access: yesGenetics and Molecular Biology, 1998
The behavioral mechanisms by which the larvae of sympatric Chilean populations of Drosophila melanogaster, D. simulans, D. hydei and D. busckii select pupation sites are described in terms of larval substrate preferences.

Adventures in Time and Space: What Shapes Behavioural Decisions in Drosophila melanogaster? [PDF]

open access: yes, 2019
Variation in behaviour can be observed both between individuals, based on their condition and experience as well as between populations due to sources of heterogeneity in the environment.

Evidence that natural selection maintains genetic variation for sleep in Drosophila melanogaster. [PDF]

open access: yes, 2015
BackgroundDrosophila melanogaster often shows correlations between latitude and phenotypic or genetic variation on different continents, which suggests local adaptation with respect to a heterogeneous environment.

Iron Absorption in Drosophila melanogaster [PDF]

open access: yesNutrients, 2013
The way in which Drosophila melanogaster acquires iron from the diet remains poorly understood despite iron absorption being of vital significance for larval growth. To describe the process of organismal iron absorption, consideration needs to be given to cellular iron import, storage, export and how intestinal epithelial cells sense and respond to ...
