We developed microsatellite markers to use in studying the population genetics of the trematode Alloglossidium renale, a fluke with a precocious life cycle where sexual maturation occurs in a grass shrimp. Among 21 tested loci in a Mississippi population sample, 14 were polymorphic, 12 of which...

Ionizing radiation can reduce survival, reproduction and affect development, and lead to the extinction of populations if their evolutionary response is insufficient. However, demographic and evolutionary studies on the effects of ionizing radiation are still scarce. Using an experimental evolution ...

Maintenance of germline function under stress conditions is crucial for species survival. The germ line in many species is especially sensitive to elevated temperature. We have investigated the role of the pocket protein LIN-35 in preserving fertility in Caenorhabditis elegans under moderate...

Sex determination and differentiation are basic events of development and key processes of sexual reproduction. The mechanism of sex determination and differentiation is both baffling and intriguing. Mollusca is the second largest animal phylum, harboring diverse sexual systems including...

Among vertebrates, fishes show an exceptional range of reproductive strategies, which can be roughly divided into three categories: gonochorism, sequential hermaphrodite and partheonogenesis. In general, gonads can differentiate into ovaries or testes after sex determination, and remain unchanged...

Introduction: Hermaphroditism is less frequently reported in dogs and is often associated with infertility. Case report: An 8-month-old French bulldog weighing 5 kg with an enlarged structure protruding from the vulva was clinically diagnosed with hermaphroditism. Physical, hormonal assay, computed ...

Most grouper species are functional protogynous hermaphrodites, but the genetic basis and the molecular mechanisms underlying the regulation of this unique reproductive strategy remain enigmatic. In this study, we report a high-quality chromosome-level genome assembly of the representative...

With the rapid development of magnetic technology, the biological effects of moderate static magnetic fields (SMFs) have attracted increasing research interest due to their potential medical diagnosis and treatment application. The present study explored the effects of moderate SMFs on the lipid...

Homozygous mutant populations are typically obtained when studying gene function using gene editing. However, because of asynchronous testicular and ovarian development, it is difficult to obtain homozygous mutant offspring of hermaphrodite fish by mating males and females. The rice field eel (...
