The Epigenetics of Sex in the Dragon. Genetic codes do not directly translate to phenotypes -- environment acts through epigenetics to modify development. We use advanced molecular techniques to examine how epigenetics responds to temperature to reverse sex in our novel animal model, the dragon lizard. How does the cell sense temperature? Once the extrinsic signal is captured, how does it influence chromatin modification to release or suppress key genes in the sex differentiation pathway? Which ....The Epigenetics of Sex in the Dragon. Genetic codes do not directly translate to phenotypes -- environment acts through epigenetics to modify development. We use advanced molecular techniques to examine how epigenetics responds to temperature to reverse sex in our novel animal model, the dragon lizard. How does the cell sense temperature? Once the extrinsic signal is captured, how does it influence chromatin modification to release or suppress key genes in the sex differentiation pathway? Which sex genes are targets? Epigenetic enzymes are astonishingly conserved, providing exciting opportunities to draw from human systems to unravel novel signatures of temperature-induced sex switching in reptiles. This project will advance knowledge of developmental programming generally.Read moreRead less
Sex determination in dragons: Genetics, epigenetics and environment. This project aims to discover the master sex-determining gene in a reptile, how that gene is differentially regulated in males and females and by temperature, and to identify evolutionary drivers of transitions between genetic and environmental sex determination. In many reptiles, like mammals, chromosomes determine sex. In others, the temperature at which their eggs are incubated determines sex. This project will study how tem ....Sex determination in dragons: Genetics, epigenetics and environment. This project aims to discover the master sex-determining gene in a reptile, how that gene is differentially regulated in males and females and by temperature, and to identify evolutionary drivers of transitions between genetic and environmental sex determination. In many reptiles, like mammals, chromosomes determine sex. In others, the temperature at which their eggs are incubated determines sex. This project will study how temperature reverses chromosomal sex determination in dragon lizards. This could show how climatic extremes affect the biology of climate sensitive reptiles, and understand their vulnerability to climate change.Read moreRead less

Increasingly, large Australian multicentre research programs in biological and medical sciences have a genomics component that involves integration of biological information with sequencing data. The success of these research programs depends on rapid internet access to the research information by all participating scientists. The universal design of the proposed information management system means that it can be easily adapted to support a broad range of research programs. The development of this software program therefore has the potential to benefit research scientists, academics and students in many related fields, as well as the broader community, through enhancing research outcomes.Read moreRead less
