Proteomic diversification of spermatostyles among six species of whirligig beetles

Project description: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 spermatophores. Here, we investigate the evolutionary diversification of a lesser-known ejaculate structure: the spermatostyle, which has independently arisen in several families of beetles and true bugs. We characterized the spermatostyle proteome, in addition to spermatostyle and FRT morphology, in six species of whirligig beetles (family Gyrinidae). Spermatostyles were enriched for proteolytic enzymes, and assays confirmed they possess proteolytic activity. Sperm leucyl aminopeptidases (S-LAPs) were particularly abundant, and their localization to spermatostyles was confirmed by immunohistochemistry. Although there was evidence for functional conservation of spermatostyle proteomes across species, phylogenetic regressions suggest evolutionary covariation between protein composition and the morphology of both spermatostyles and FRTs. We postulate that S-LAPs (and other proteases) have evolved a novel structural role in spermatostyles and discuss spermatostyles as adaptations for delivering male-derived materials to females.

Convergence, recurrence and diversification of complex sperm traits in diving beetles (Dytiscidae).

Project description:Sperm display remarkable morphological diversity among even closely related species, a pattern that is widely attributed to postcopulatory sexual selection. Surprisingly few studies have used phylogenetic analyses to discern the details of evolutionary diversification in ornaments and armaments subject to sexual selection, and the origins of novel sperm traits and their subsequent modification are particularly poorly understood. Here we investigate sperm evolution in diving beetles (Dytiscidae), revealing dramatic diversification in flagellum length, head shape, presence of sperm heteromorphism, and the presence/type of sperm conjugation, an unusual trait where two or more sperm unite for motility or transport. Sperm conjugation was found to be the ancestral condition in diving beetles, with subsequent diversification into three forms, each exhibiting varying degrees of evolutionary loss, convergence, and recurrence. Sperm head shape, but not length or heteromorphism, was found to evolve in a significantly correlated manner with conjugation, consistent with the different mechanisms of head alignment and binding required for the different forms of conjugation. Our study reveals that sperm morphological evolution is channeled along particular evolutionary pathways (i.e., conjugate form), yet subject to considerable diversification within those pathways through modification in sperm length, head shape, and heteromorphism.

Effects of offshore saturation diving on the human peripheral blood transcriptome

Project description:Illumina HT-12 v4 microarrays were used to measure genome-wide gene expression in peripheral blood from occupational offshore divers, all male and fulfilling the criteria for diving personnel set in the NORSOK U-100 standard for manned underwater operations. Saturation dives lasted 13 - 20 days, with maximal diving depths 100 - 125 mws. Elevated oxygen during deep saturation dives triggers oxidative stress. To test the effects of oral antioxidants on post-dive gene expression, the divers were divided into two groups: one group (13 divers) received daily supplementation of antioxidant vitamins C (500mg/day) and E (200mg/day) during their dives, the other (7 divers) was not.

Survey of methylomes of two beetles, Nicrophorus vespilloides and Tribolium castaneum

Project description:The presence of DNA methylation in beetles (Coleoptera) has only been investigated with bisulfite sequencing of Tribolium castaneum, which produced no evidence of DNA methylation. Here, we used whole genome bisulfite sequencing to assay if DNA methylation was present in another beetle, Nicrophorus vespilloides. We used T. castaneum as a negative control.
