Data from: Multiple sexual selection pressures drive the rapid evolution of complex morphology in a male secondary genital structure
The genitalia of internally fertilizing taxa represent a striking example of rapid morphological evolution. Although sexual selection can shape variation in genital morphology, it has been difficult to test whether multiple sexual selection pressures combine to drive the rapid evolution of individual genital structures. Here, we test the hypothesis that both pre- and postcopulatory sexual selection can act in concert to shape complex structural variation in secondary genital morphology. We genetically modified the size and shape of the posterior lobes of Drosophila melanogaster males and tested the consequences of morphological variation on several reproductive measures. We found that the posterior lobes are necessary for genital coupling and that they are also the targets of multiple postcopulatory processes that shape quantitative variation in morphology, even though these structures make no direct contact with the external female genitalia or internal reproductive organs during mating. We also found that males with smaller and less structurally complex posterior lobes suffer substantial fitness costs in competitive fertilization experiments. Our results show that sexual selection mechanisms can combine to shape the morphology of a single genital structure and that the posterior lobes of D. melanogaster are the targets of multiple postcopulatory selection pressures.
Data from: HSP90 as a global genetic modifier for male genital morphology in Drosophila melanogaster
The molecular chaperone protein HSP90 has been proposed to modulate genotype-phenotype relationship in a broad range of organisms. To understand the genetic modifier effect of HSP90, genetic variations under the influence of HSP90 need to be identified on a genome-wide scale. Here, we show that HSP90 functions as a genetic modifier of genital morphology in Drosophila melanogaster. We identified a large number of single-nucleotide polymorphisms (SNPs) with an HSP90-dependent effect by using genome wide association analysis. We classified the SNPs into the ones under capacitance effect (smaller allelic effect under HSP90 inhibition) or the ones under potentiation effect (larger allelic effect under HSP90 inhibition). Although the majority of SNPs are under capacitance, there are a large number of SNPs under potentiation. This observation provides support for a model in which Hsp90 is not described exclusively as a 'genetic capacitor', but is described more broadly as a 'genetic modifier'. Because the majority of the candidate genes estimated from SNPs with an HSP90-dependent effect in the current study have never been reported to interact with HSP90 directly, the global genetic modifier effect of HSP90 may be exhibited through epistatic interactions in gene regulatory networks.

Data set: Reproductive character displacement in genital morphology in Ohomopterus ground beetles
<p>Genital morphology reveals rapid diversification among species, and species-specific divergence in genital morphology may result in reproductive isolation and promote speciation. Natural selection against maladaptive hybridization may cause species-specific genital divergence. In this context, divergence in mating traits is expected to be greater between sympatric populations than between allopatric populations in a pair of species, known as reproductive character displacement (RCD). However, there are few examples of RCD in the genital morphology of closely related species. Additionally, processes leading to RCD have rarely been inferred. In this study, we examined RCD and its underlying mechanisms by focusing on species-specific genital morphologies of closely related <i>Ohomopterus</i>ground beetle species. A morphological analysis showed patterns of RCD in species-specific genital parts in both sexes. Interspecific hybridization was confirmed by a mate choice experiment and by a population genetic analysis indicating extensive interspecific gene flow, suggesting that reinforcement is the most plausible process underlying the observed RCD. We found variation in the degree of displacement in contact zones, which may correspond with the ongoing process of genital evolution and speciation. Our results provide support for the lock-and-key hypothesis of genital evolution in closely related <i>Ohomopterus </i>species.</p>
