“…The consistent use of cadherin hetero-allelic sperm by females found here supports the hypothesis that differential sperm retention or displacement was mediated by male × female interactions (Eberhard, 1996; Simmons, 2001). Genetically based male × female interactions are important determinants of paternity success in mice, fruit flies and beetles (Pitnick et al, 2009).…”

Cadherin mutation linked to resistance to Cry1Ac affects male paternity and sperm competition in Helicoverpa armigera

Several lepidopteran pests of cotton have cadherin-based resistance to the Bacillus thuringiensis (Bt) toxin Cry1Ac. Cadherins are transmembrane proteins that mediate cell-cell adhesion and tissue morphogenesis, suggesting that fitness costs associated with cadherin mutations may be present in many aspects of life history. To evaluate whether cadherin-based resistance is associated with fitness costs reducing male paternity in Helicoverpa armigera, we examined the effects of a major cadherin resistance allele on sperm competition within and between male ejaculates. When homozygous resistant and susceptible males competed for fertilization of a homozygous resistant or susceptible female, fertilization success was high in males with a different cadherin genotype than females and low in males with the same cadherin genotype as females. Single matings between heterozygous males and susceptible females produced offspring within typical Mendelian ratios. Heterozygous males mated to resistant females, however, resulted in a disproportionate number of heterozygous offspring. While these results show that cadherin-based resistance to Cry1Ac has significant impacts on paternity in H. armigera, there was no evidence that costs associated with resistance consistently reduced male paternity. Rather, effects of cadherin-based resistance on paternity depended on interactions between male and female genotypes and differed when males or sperm competed for fertilization of females, which complicates assessment of impacts of cadherin resistance alleles on resistance evolution.

“…In most insect species, females mate multiply with several males and competition between ejaculates and cryptic female choice of sires is widespread (Eberhard 1996; Simmons, 2001). Nevertheless, few studies have analyzed the potential impacts of Bt resistance on sperm competition.…”

Sexual reproduction requires coordinated contributions from both sexes to proceed efficiently. However, the reproductive strategies that the sexes adopt often have the potential to give rise to sexual conflict because they can result in divergent, sex-specific costs and benefits. These conflicts can occur at many levels, from molecular to behavioral. Here, we consider sexual conflict mediated through the actions of seminal fluid proteins. These proteins provide many excellent examples in which to trace the operation of sexual conflict from molecules through to behavior. Seminal fluid proteins are made by males and provided to females during mating. As agents that can modulate egg production at several steps, as well as reproductive behavior, sperm “management,” and female feeding, activity, and longevity, the actions of seminal proteins are prime targets for sexual conflict. We review these actions in the context of sexual conflict. We discuss genomic signatures in seminal protein (and related) genes that are consistent with current or previous sexual conflict. Finally, we note promising areas for future study and highlight real-world practical situations that will benefit from understanding the nature of sexual conflicts mediated by seminal proteins.

“…Darwin's definition of sexual selection is very similar to the more modern definition of pre-copulatory sexual selection in animals (Andersson 1994; Jones and Ratterman 2009). However, along with the application of this theory to more taxa (hermaphrodite species, plants) and post-copulatory stages of the life cycle, the definition has been extended to include sexual reproductive functions (rather than sexes) and competition over fertilizations and embryo investment (Arnold 1994; Morgan 1994; Eberhard 1996; Skogsmyr and Lankinen 2002; Jones and Ratterman 2009; Moore and Pannell 2011). It should be noted that even though competition over fertilization at post-copulatory stages will involve competition between haploid sperm or pollen, the definition implies that sperm and pollen traits can only be sexually selected if these traits enhance reproductive success of the sperm- or pollen-producing diploid individual (Parker 1970; Willson 1979).…”

Sexual selection and sexual conflict theories that explain evolution of sexual behaviour are often an integral part of animal studies investigating diverse research questions, e.g. in behaviour, ecology, physiology and immunology. In plants, however, relatively few studies investigate sexual selection and sexual conflict. In this review we discuss how taking these theories into account can be useful not only for our understanding of plant reproductive strategies but also in related research areas, including i) mechanisms of pollen-pistil interactions, ii) mating-system evolution in hermaphrodites and iii) plant immune responses to pests and pathogens.
