Predaceous Diving Beetle Sexual Systems
Diving beetles have an impressively diverse array of morphological and behavioral attributes associated with sexual systems. These include anatomical...

The roles of sexual selection and sexual conflict in sha** patterns of genome and transcriptome variation
Sexual dimorphism is one of the most prevalent, and often the most extreme, examples of phenotypic variation within species, and arises primarily...

Sexual System and Its Evolution
Sexual systems in tree crop species is often an important determinant of stable and efficient fruit production, and harnessing them is a key for both...
-
Sexual determination in zebrafish
Zebrafish have emerged as a major model organism to study vertebrate reproduction due to their high fecundity and external development of eggs and...
-
Sexual conflict drives micro- and macroevolution of sexual dimorphism in immunity
BackgroundSexual dimorphism in immunity is believed to reflect sex differences in reproductive strategies and trade-offs between competing life...

Selection drives convergent gene expression changes during transitions to co-sexuality in haploid sexual systems
Co-sexuality has evolved repeatedly from unisexual (dioicous) ancestors across a wide range of taxa. However, the molecular changes underpinning this...

Investigating the interaction between inter-locus and intra-locus sexual conflict using hemiclonal analysis in Drosophila melanogaster
BackgroundDivergence in the evolutionary interests of males and females leads to sexual conflict. Traditionally, sexual conflict has been classified...

Sexual maturation inhibition using exemestane and tamoxifen in female olive flounder (Paralichthys olivaceous)
Sex determination in some reptiles, amphibians, and fishes is influenced by environmental factors. Exemestane acts as an estrogen agonist non-steroid...

Switching it up: algal insights into sexual transitions
While the process of meiosis is highly conserved across eukaryotes, the sexual systems that govern life cycle phase transitions are surprisingly...

Melatonin and Sexual Maturation in Bank (Clethrionomys glareolus) and Grey-Sided (Clethrionomys rufocanus) Voles in Experimental Conditions
AbstractWe tested the effects of melatonin on sexual maturation in the bank vole Clethrionomys glareolus and grey-sided vole C. rufocanus through an...

Functional characterization of the AGL1 aegerolysin in the mycoparasitic fungus Trichoderma atroviride reveals a role in conidiation and antagonism
Aegerolysins are small secreted pore-forming proteins that are found in both prokaryotes and eukaryotes. The role of aegerolysins in sporulation,...

Genomic evidence that a sexually selected trait captures genome-wide variation and facilitates the purging of genetic load
The evolution of costly traits such as deer antlers and peacock trains, which drove the formation of Darwinian sexual selection theory, has been...

Sex-biased genes and metabolites explain morphologically sexual dimorphism and reproductive costs in Salix paraplesia catkins
Dioecious species evolved from species with monomorphic sex systems in order to achieve overall fitness gains by separating male and female...

Multivariate selection and the making and breaking of mutational pleiotropy
The role of mutations have been subject to many controversies since the formation of the Modern Synthesis of evolution in the early 1940ties....

Evolution of reduced mate harming tendency of males in Drosophila melanogaster populations selected for faster life history
AbstractDetrimental effect of males on female, often termed mate harm, is a hallmark of sexual conflict. Allowed to evolve unchecked, mate harming...

Sex Steroid Regulation of Male- and Female-Typical Mating Behaviors in Teleost Fish
Males and females exhibit innate sex-specific mating behaviors, which are established developmentally. In mammals and birds, phenotypic sex...

Evolutionary dynamics of pseudoautosomal region 1 in humans and great apes
BackgroundThe pseudoautosomal region 1 (PAR1) is a 2.7 Mb telomeric region of human sex chromosomes. PAR1 has a crucial role in ensuring proper...

Trichoderma: a multipurpose, plant-beneficial microorganism for eco-sustainable agriculture
Trichoderma is a cosmopolitan and opportunistic ascomycete fungal genus including species that are of interest to agriculture as direct biological...

Characterization of the fungal genus Sphaerellopsis associated with rust fungi: species diversity, host-specificity, biogeography, and in-vitro mycoparasitic events of S. macroconidialis on the southern corn rust, Puccinia polysora
Sphaerellopsis species are putative hyperparasites of rust fungi and may be promising biological control agents (BCA) of rust diseases. However, few...

An alternative hypothesis for the evolution of same-sex sexual behaviour in animals
Same-sex sexual behaviour (SSB) has been recorded in over 1,500 animal species with a widespread distribution across most major clades. Evolutionary...
