Molecular mechanisms of sex determination in reptiles and amphibians in Kansas City

Masuyama, R. This is the first experimental demonstration of a link between a well-described thermo-sensory mechanism, TRPV4 channel and its potential role in regulation of TSD in vertebrates, shedding unique new light on the elusive TSD molecular mechanism.

Genetic evidence for co-occurrence of chromosomal and thermal sex-determining systems in a lizard. Ortholog names are listed below and the genomic location of the orthologs are listed on the right side. We are conducting additional studies of this gene to explore its potential role in TSD in the snapping turtle.

  • Charles Darwin first provided a lucid explanation of how gender differences evolve nearly years ago. Yet, a disconnect remains between his theory of sexual selection and the mechanisms that underlie the development of males and females.

  • Choosing Sexes pp Cite as. In many reptiles, amphibians, and fishes, the environment plays a key role in determining the sexes of individuals.
  • Determining sexual fate is an integral part of reproduction, used as a means to enrich the genome. A variety of such regulatory mechanisms have been described so far and some of the more extensively studied ones are being discussed.

As a result, due to a lack of significantly altered CYP19A1 expression, feminization of RNtreated embryos incubated at MPT was very limited: that is, we were not able to induce a feminized gene expression pattern in the gonad following inhibition of AmTRPV4 suggesting that this channel is not effective in the ovarian pathway.

RADSex groups demultiplexed reads sharing the exact same sequence into markers, and thus reads belonging to the same polymorphic locus are split into multiple markers. However, our study, as well as other recent efforts in characterizing sex loci in non-model species [ 75 ], show that current population genomic approaches can now relatively easily identify and characterize small sex loci.
