The genetic regulation of organogenesis: endoderm development in the Drosophila embryo. Embryonic development is an important research field in biology, not only for its extraordinary complexity but also because of the insights it provides into molecular processes that underpin a variety of diseases. This project aims to discover genes and molecules that regulate the normal development of one of the most important organs, the gut.

Summary
Investigating the Genetic Basis of Human Intrinsic Capacity. Intrinsic capacity is a new concept introduced by experts at the World Health Organisation to promote healthy ageing. It is defined as the composite of an individual’s physical and mental capacities, based on measures of five criteria; cognitive, sensory, locomotor, vitality and psychological. It is a genetically predetermined trait, but is influenced by a range of environmental stimuli. Applying a cutting-edge genetic methodology on b ....Investigating the Genetic Basis of Human Intrinsic Capacity. Intrinsic capacity is a new concept introduced by experts at the World Health Organisation to promote healthy ageing. It is defined as the composite of an individual’s physical and mental capacities, based on measures of five criteria; cognitive, sensory, locomotor, vitality and psychological. It is a genetically predetermined trait, but is influenced by a range of environmental stimuli. Applying a cutting-edge genetic methodology on big biobank datasets, this project aims to examine the role of genetics and the environment to explain the variability of intrinsic capacity between individuals. Understanding the biological basis of intrinsic capacity has major implications for scientific research in healthy ageing and mental wellbeing.Read moreRead less
Defining the earliest events in lymphatic vasculature formation from veins. Vascular system development is one of the earliest events that occurs in the embryo. The entire lymphatic vascular system forms from the embryo’s early veins. This project aims to define the earliest molecular and cellular changes essential to form an entire second vessel network from just a few precursor cells in the embryo. The project aims to utilise zebrafish and mouse embryos to greatly expand knowledge in the forma ....Defining the earliest events in lymphatic vasculature formation from veins. Vascular system development is one of the earliest events that occurs in the embryo. The entire lymphatic vascular system forms from the embryo’s early veins. This project aims to define the earliest molecular and cellular changes essential to form an entire second vessel network from just a few precursor cells in the embryo. The project aims to utilise zebrafish and mouse embryos to greatly expand knowledge in the formation of this essential vertebrate tissue. Ultimately, this is expected to provide new knowledge in stem and precursor cell differentiation, the evolution of complex organ systems and tissue formation. Outcomes may impact on future biotechnology in the areas of tissues engineering, stem cell differentiation and regeneration.Read moreRead less
Solving the Mysteries of Monotreme Chromosomes. The peculiar chromosomes of Australia's platypus and echidna have been debated for more than 30 years. Classical cytology cannot resolve the puzzling sex chromosome system, or to sort out the bizarre translocation chain (unique in vertebrates) and deduce how it segregates to make viable zyotes. I will microdissect individual chromosomes, and use DNA ?paints? from them (and gene probes isolated by them) to detect homologies between unpaired chromoso ....Solving the Mysteries of Monotreme Chromosomes. The peculiar chromosomes of Australia's platypus and echidna have been debated for more than 30 years. Classical cytology cannot resolve the puzzling sex chromosome system, or to sort out the bizarre translocation chain (unique in vertebrates) and deduce how it segregates to make viable zyotes. I will microdissect individual chromosomes, and use DNA ?paints? from them (and gene probes isolated by them) to detect homologies between unpaired chromosomes at mitosis, meiosis and in sperm. I will use immunohistochemistry to clarify chromosome pairing and recombination at meiosis. This will answer some important general questions about chromosome behaviour and sex chromosome evolution.

Genetic control of floral architecture. Different flowers have different designs, and so the design must ultimately be controlled by genes. We have identified a gene that keeps sepals separate, and promotes the initiation of petals. We think it does this by a novel growth suppression mechanism, and will now deduce its molecular and cellular basis. This will help maintain Australia's strength in fundamental plant biology. Also, by understanding how sepals and petals arise in a model laboratory sp ....Genetic control of floral architecture. Different flowers have different designs, and so the design must ultimately be controlled by genes. We have identified a gene that keeps sepals separate, and promotes the initiation of petals. We think it does this by a novel growth suppression mechanism, and will now deduce its molecular and cellular basis. This will help maintain Australia's strength in fundamental plant biology. Also, by understanding how sepals and petals arise in a model laboratory species, we can generalise for many species, including economic plants. Thus it may be possible to make designer crops through targeted genetic changes to their floral structure.Read moreRead less
Control of plant organ development by the PETAL LOSS gene of Arabidopsis. We have discovered a new gene in the model laboratory plant Arabidopsis thaliana that is involved in sepal and petal development. It encodes a transcription factor that apparently acts by repressing growth in the inter-sepal zone of flowers where petals arise. We now aim to determine how this growth suppression occurs, and whether it extends to leaves where the gene is also expressed. Control of the initiation and sculptur ....Control of plant organ development by the PETAL LOSS gene of Arabidopsis.

It encodes a transcription factor that apparently acts by repressing growth in the inter-sepal zone of flowers where petals arise. We now aim to determine how this growth suppression occurs, and whether it extends to leaves where the gene is also expressed. Control of the initiation and sculpturing of plant organs by site-specific inhibition of growth is a newly discovered mechanism that may be useful in manipulating plant architecture.Read moreRead less
Understanding how auxin and dorsoventral patterning are coordinated in plants. This study will help reveal for the first time how the outgrowth of leaves, flowers and floral organs is coordinated by tissue patterning genes and the plant growth hormone auxin. All plants grow in this way, and our findings, made using a model laboratory plant, will be applicable to crop species as well. Thus we will both expand our core knowledge of how multicellular organisms are constructed, and also generate pos ....Understanding how auxin and dorsoventral patterning are coordinated in plants.

All plants grow in this way, and our findings, made using a model laboratory plant, will be applicable to crop species as well. Thus we will both expand our core knowledge of how multicellular organisms are constructed, and also generate possibilities for modifying the patterns of leaf and flower development in agricultural and horticultural species. Crops with larger leaves, or flowers of different structure, may result.Read moreRead less
Understanding the molecular mechanisms of intellectual disability. Intellectual disability is frequent in the population, with one in every fifty people in the world directly affected. This project will improve our understanding of the correct development and function of the brain required for cognition by investigating specific roles and regulation of key molecules involved.
Unveiling the epigenome dynamics through the pluripotency continuum. This project aims to utilise stem cells and genomics based technologies, in combination with new computational algorithms to dissect the fundamental molecular events that drive the first steps during development. The project is expected to unveil the basic mechanisms underpinning how genes driving the developmental master plan are controlled in cells that have the capacity to give rise to the whole organism and placenta.

The project is expected to unveil the basic mechanisms underpinning how genes driving the developmental master plan are controlled in cells that have the capacity to give rise to the whole organism and placenta. The knowledge gained from this work will inform and guide future novel approaches, such as in assisted reproductive technologies or regenerative medicine.Read moreRead less
