Empirical approaches to detecting the action of natural selection in Drosophila

, 2004
This dissertation examines two aspects of how natural selection shapes the amount and pattern of genetic variation within and between species: (1) the role of positively selected alleles in shaping the variation within and between subpopulations of a ...

Finding Mr. Right: Housing Quality Affects Male Mouse Attractiveness to Females, With Implications for Conservation Captive Breeding

Zoo Biology, EarlyView.
Housing quality affects male mouse attractiveness to females ABSTRACT Females generally prefer mates with traits indicating low stress (e.g., large size; good health). In captivity, stress from suboptimal housing might therefore reduce male attractiveness.

Structure of the Arabidopsis receptor kinase SRF6 ectodomain determined from crystals obtained using the LRR crystallization screen

Acta Crystallographica Section D, EarlyView.
A crystallization screen that has enabled the structural analysis of various extracellular domains of plant membrane receptor kinases is described together with the structure of the LRR domain of the receptor SRF6.Plant‐specific membrane receptor kinases with structurally diverse extracellular domains regulate key processes in plant growth, development,

Control of expression of the I factor, a LINE-like transposable element in Drosophila melanogaster

, 1996
I factors are LINE-like transposable elements in the genome of Drosophila melanogaster. They normally transpose infrequently but are activated in the germline of female progeny of crosses between males of a strain that contains complete elements, an I or

Mycotoxins‐contaminated wheat matrices bioconversion by Tenebrio molitor larvae (Coleoptera: Tenebrionidae)

Insect Science, EarlyView.
Larval development time, ADG, survival rate and substrate consumption were not negatively affected by the levels of mycotoxins contamination Larvae excreted most of the ingested DON and its derivatives through exuviae and frass The mycotoxin accumulation rates observed in larvae were always below the current legal limits for livestock feed Abstract ...

Genetic and phenotypic variation in wood tiger moths from the Caucasus: insights into male warning color variation

Insect Science, EarlyView.
Coloration serves several fitness‐related functions, including thermoregulation, immunity, social signaling, sexual selection, and predator avoidance. Consequently, color polymorphism can have a significant impact on a species’ interactions with its environment, including its relationships with predators, prey, and potential mates. The wood tiger moth (

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

Drosophila Melanogaster as a Model for Molybdo-Flavoenzyme Mediated Protection against Chemical and Physical Stress

Aldehyde oxidase (AO) and xanthine oxidoreductase (XOR) are molybdo-flavoenzymes (MFEs) involved in the oxidation of hundreds of endogenous and exogenous aldehydes and N-heterocyclic compounds many of which are drugs, vitamins and environmental ...
