Summary
Evolution of genome architecture. The project aims to understand how changes to genome architecture over evolutionary time are linked to the diversity of animal morphology. Our genome sequence is arranged into higher order structures that enable coordinated gene expression. The appropriate expression of genes in time and space is necessary to produce the multitude of cell types that make up a multicellular organism. Yet, to date, genome topology is poorly explored, especially between species. Th ....Evolution of genome architecture. The project aims to understand how changes to genome architecture over evolutionary time are linked to the diversity of animal morphology. Our genome sequence is arranged into higher order structures that enable coordinated gene expression. The appropriate expression of genes in time and space is necessary to produce the multitude of cell types that make up a multicellular organism. Yet, to date, genome topology is poorly explored, especially between species. The project involves comparisons of the 3D structure of genomes in divergent species. These findings are expected to inform the underlying principles of gene regulation in animals and species evolution.Read moreRead less
Morphological development of the kidney – a paradigm for organogenesis. This project aims to shed new light on how the kidney develops, how normal adult function is established and how congenital kidney malformations occur. It aims to investigate a mathematical pattern that has been discovered in the program of branching morphogenesis which dictates kidney development. By combining cutting-edge genetic approaches, morphological analysis and mathematical modelling, this project plans to explore h ....Morphological development of the kidney – a paradigm for organogenesis. This project aims to shed new light on how the kidney develops, how normal adult function is established and how congenital kidney malformations occur. It aims to investigate a mathematical pattern that has been discovered in the program of branching morphogenesis which dictates kidney development. By combining cutting-edge genetic approaches, morphological analysis and mathematical modelling, this project plans to explore how this pattern is established, how it dictates kidney development and whether it constitutes an ancient mechanism central to organ formation. Project outcomes may improve understanding of fundamental developmental processes and developmental disease and variation. Project findings may also be important for understanding the development of other organ systems.Read moreRead less
Evolutionary origin of stem cells and the emergence of animal complexity. The project aims to decipher the fundamental mechanisms governing stem cell specification and formation. All animals rely on stem cells to replenish, repair and regenerate tissues. Stem cells are also often a conduit to malignant tumours. This project seeks to uncover the rules governing stem cell formation through the study of a simple and ancient animal – the marine sponge Amphimedon queenslandica.

The project aims to decipher the fundamental mechanisms governing stem cell specification and formation. All animals rely on stem cells to replenish, repair and regenerate tissues. Stem cells are also often a conduit to malignant tumours. This project seeks to uncover the rules governing stem cell formation through the study of a simple and ancient animal – the marine sponge Amphimedon queenslandica. The project plans to combine insights from the simple, experimentally-tractable sponge stem cell system with existing knowledge of stem cell specification in humans and other animals, to reveal the essential features of stem cell formation. These insights may inform future pursuits to generate, control and use stem cells in cancer and regenerative medicines.Read moreRead less
Origin of genomically-encoded communication in animals: deciphering the role of peptide signalling in the sea sponge Amphimedon queenslandica. The purpose of this research is to understand the evolutionary origin and essential roles of peptide communication in humans and other animals. Knowledge gleaned from this study will shed light on how peptide signalling influences animal life at its most fundamental level, including potentially how abnormal cell communication causes disease.

Summary
Using sponge transcriptomes to understand ancestral animal development. The invention of a basic developmental program was likely a key step in the transition to multicellularity in animals, one of the major transitions in the tree of life. By combining next-generation sequencing of a representative panel of sponges and functional studies on an oviparous sponge, this project aims to identify gene interactions and networks that built the first animal embryos over 680 million years ago.

The invention of a basic developmental program was likely a key step in the transition to multicellularity in animals, one of the major transitions in the tree of life. By combining next-generation sequencing of a representative panel of sponges and functional studies on an oviparous sponge, this project aims to identify gene interactions and networks that built the first animal embryos over 680 million years ago. Furthermore, the role of Wingless (Wnt) signalling in patterning these ancestral embryos along a primordial anterior-posterior axis will be investigated. Piecing together the fundamental molecular machinery shared by all animal embryos will shed light on the molecular basis for the complex development of most animals on Earth.Read moreRead less

Summary
Origin, evolution and roles of cardinal genomic features underpinning animal multicellular complexity. As the first genome project from our oceans, the sea sponge Amphimedon heralds a new era of marine science for Australia. Using post-genomic approaches, this project will show how studying marine organisms can produce the most fundamental insights into not only multicellular life but also into human diseases and cancer that originally evolved from our oceans.
The molecular evolution of wings in flightless birds. The flightless Australian emu and New Zealand kiwi have small wings, while the extinct moa had none at all. This project will identify the genetic changes that have lead to wing reduction and loss in flightless birds. The results will shed light on the genetic control of forelimb development and how it has evolved.
