Mutation processes in the natural population of Drosophila melanogaster from radiation contaminated territories

Фактори експериментальної еволюції організмів, 2013
Aims. Explore mutational processes in natural populations of Drosophila melanogaster that inhabit the territories with different levels of radioactive contamination. Methods.

The endosymbiont Wolbachia increases insulin/IGF-like signalling in Drosophila [PDF]

, 2009
Insulin/IGF-like signalling (IIS) is an evolutionarily conserved pathway that has diverse functions in multi-cellular organisms. Mutations that reduce IIS can have pleiotropic effects on growth, development, metabolic homeostasis, fecundity, stress ...

The oxygen and pressure physiology of upper elevational range limits in insects

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Climate warming is widely expected to cause montane insects to shift upslope, and there is good evidence that some populations are doing so. Nevertheless, patterns are mixed—with evidence supporting upslope, downslope or even no movement of both lower and upper range ...

The consequences of host heterogeneity for parasite transmission depend on how host infectiousness is determined

Journal of Animal Ecology, EarlyView.
This study proposes two contrasting scenarios for how host infectiousness is determined: recipient dependence and donor dependence. These scenarios fundamentally alter how host heterogeneity shapes parasite transmission, demonstrating that the process by which infectiousness is determined is crucial for understanding the consequences of host ...

Hobo transposon in the natural populations of Drosophila melanogaster in Ukraine

Фактори експериментальної еволюції організмів, 2013
Aims. The goal of our study was to investigate population dynamics of the hobo transposon in the wild population of Drosophila melanogaster in Ukraine. Methods. Samples from the wild populations were collected across 11 different locations.

RNS interferencia alkalmazása géncsendesítésre Drosophila melanogaster-ben

, 2012
Különböző laboratóriumi Drosophila törzseket keresztezve RNS interferenciát hoztam létre Drosophila melanogaster-ben. Ennek hatására a CG9238 gén expressziója nagymértékben csökkent, így ezek az egyedek alkalmasak a gén funkciójának vizsgálatára ...

Silencing of juvenile hormone‐related genes through RNA interference leads to molt failure and high mortality in the spongy moth

Insect Science, EarlyView.
The feasibility of using RNA interference to control the globally important quarantine pest, the spongy moth. Targeting genes related to JHs play an important role in the growth and development of insects. First, the open reading frames (ORFs) of Ldjhamt and Ldjheh were identified and characterized, and the target genes were cloned and double‐stranded ...

Full‐length transcriptome profiling of true bug mitochondrial genomes reveals the unique transcriptional regulation during insect evolution

Insect Science, EarlyView.
The mitogenome was transcribed into complete primary polycistrons on both strands. The heteropteran mitochondrial transcription termination factor (HmTTF) functions as a bidirectional attenuator rather than a terminator, and co‐evolution of HmTTF and the binding sites was observed.

Calcitonin‐like diuretic hormone influences reproduction in adult female Rhodnius prolixus

Insect Science, EarlyView.
Highlights • CT/DH‐like immunoreactivity is present in female reproductive tissues • CT/DH receptor transcripts are expressed in the fat body and ovaries • RNAi knockdown of CT/DH receptors reduces egg number and hatching rate • Rhopr‐CT/DH increases RhoprVg1 and RhoprVgR expression in ovaries in vitro • Rhopr‐CT/DH stimulates oviduct contractions in a

Search for new genes involved in Drosophila circadian rhythmicity: behavioural analysis of putative CRYPTOCHROME interacting proteins and molecular characterization of the ubiquitin protease USP5 [PDF]

, 2009
Drosophila melanogaster, il moscerino della frutta, si è rivelato un ottimo modello per identificare le basi molecolari dei ritmi circadiani. In particolare, il moscerino condivide con i mammiferi omologhi la gran parte dei geni coinvolti nell ...
