Defining the Molecular Targets of Evolution. With significant advances in next-generation sequencing technologies we now have the genomes of hundreds vertebrate species, but understanding how the differences and similarities within these genomes control species diversity is largely unknown. The similarity in skull shape between the thylacine and dogs coupled with their deep ancestry, having last shared a common ancestor over 160 million years ago, provides an unprecedented opportunity to examine ....Defining the Molecular Targets of Evolution. With significant advances in next-generation sequencing technologies we now have the genomes of hundreds vertebrate species, but understanding how the differences and similarities within these genomes control species diversity is largely unknown. The similarity in skull shape between the thylacine and dogs coupled with their deep ancestry, having last shared a common ancestor over 160 million years ago, provides an unprecedented opportunity to examine how evolution works at the DNA level. This proposal will determine if animals that develop identical skull shapes, also show identical changes in their DNA. The findings will define new developmental genes and explain how selection, adaptation and evolution works at the DNA level. Read moreRead less
Genetic regulation of wing reduction in the emu. This project aims to examine the genetic mechanisms that generate limb diversity, using wing reduction in the emu as a model. A hot topic in biology at present is evolutionary developmental biology, or how genes control morphological diversity. This project will explore the functions of two novel genes implicated in wing reduction. The project expects to expand knowledge in the area of developmental biology, and limb morphogenesis specifically. It ....Genetic regulation of wing reduction in the emu. This project aims to examine the genetic mechanisms that generate limb diversity, using wing reduction in the emu as a model. A hot topic in biology at present is evolutionary developmental biology, or how genes control morphological diversity. This project will explore the functions of two novel genes implicated in wing reduction. The project expects to expand knowledge in the area of developmental biology, and limb morphogenesis specifically. It will bear upon the phylogeny of flightlessness among birds. It also has potential implications for studying human limb deformities. Overall, the project will enhance our understanding of how genes control the great diversity that we see in nature.Read moreRead less
The role of Roquin in microRNA function and decay. The aim of this study is to understand how microRNAs (newly discovered genetic components that control cell growth and survival) function and are regulated. The expected discoveries will help understand how common cancers including breast cancer and autoimmune diseases emerge, and will help develop cutting edge genetic technologies.
