ProteomicsInfection by wMel Wolbachia alters female post-mating behaviors and physiology in the dengue vector mosquito Aedes aegypti
Globally invasive Aedes aegypti mosquitoes disseminate numerous arboviruses that impact human health. One promising method to control Ae. aegypti populations is transinfection with the intracellular bacterium Wolbachia pipientis, a symbiont that naturally infects ~40-52% of insects but is normally a...

TranscriptomicsSpermatozoal mRNA is reproducibly detected in purified D. melanogaster sperm.
It is now well established that mature mammalian spermatozoa carry a population of mRNA molecules, at least some of which are transferred to the oocyte at fertilisation. However, the function of the sperm transcriptome remains largely unclear. To shed light on the evolutionary conservation of this...

ProteomicsProteomic diversification of spermatostyles among six species of whirligig beetles
Seminal fluid protein (SFP) composition is complex and commonly assumed to be rapidly divergent due to functional interactions with both sperm and the female reproductive tract (FRT), both of which evolve rapidly. In addition to sperm, seminal fluid may contain structures, such as mating plugs and s...

ProteomicsEvolution of sperm conjugation in the arthropod tree of life
We investigated the evolution of sperm conjugation in phylum Arthropoda by reconstructing its diversification along a time-calibrated phylogeny for 621 arthropods and related ecdysozoans. Phylogenetic modeling reveals conjugation has had a dynamic evolution history with multiple origins of all five ...

ProteomicsEfficiency of isotopic labbeling in whole Drosophila body
We used isotopic (heavy) labelling to delineate between female and male proteins interacting in the female reproductive tract. Here, we test the efficiency of the labelling protocols on the whole body of males and females.

ProteomicsFemale mating status influences protein composition of mature Drosophila oocytes
Oocyte composition can directly influence offspring fitness, particularly in oviparous species such as most insects, where it is the primary form of parental investment. Oocyte production is also energetically costly, dependent on female condition and responsive to external cues. We investigated whe...

ProteomicsProteomic differences between Drosophila melanogaster female reproductive tract tissue and fluid and their postmating responses
Fertility depends on the progression of complex and coordinated postmating processes within the extracellular luminal environment of the female reproductive tract (FRT). To achieve a more comprehensive level of knowledge regarding female-derived proteins available to interact with the ejaculate, we ...

ProteomicsDrosophila female reproductive glands contribute to mating plug composition and the timing of sperm ejection
Reproductive traits that influence female remating and competitive fertilization rapidly evolve in response to sexual selection and sexual conflict. One such trait, observed across diverse animal taxa, is the formation of a structural plug inside the female reproductive tract, either during or short...

ProteomicsThe life history of Drosophila sperm depends on molecular continuity between male and female reproductive tracts: heavy-female isotopic labeling to estimate abundances of female-derived sperm protein
Interactions between sperm and the female reproductive tract (FRT) are critical to fertility, but knowledge of the molecular mechanisms by which the FRT interacts with sperm and influences sperm fate remains limited. Here, we used sex-specific isotopic labeling to estimate the relative abundance of ...
