Adaptation to life in the dark: genomic analyses of blind beetles. This project aims to utilise a unique Australian model system based on multiple, independently-evolved subterranean water beetles to explore the adaptive and regressive changes in the genome that occur when surface species colonise subterranean habitats. This project focuses on the evolution of Heat Shock protein (Hsp) genes that play critical roles in adaptation to environmental stress and the process of de-canalisation, the rel ....Adaptation to life in the dark: genomic analyses of blind beetles. This project aims to utilise a unique Australian model system based on multiple, independently-evolved subterranean water beetles to explore the adaptive and regressive changes in the genome that occur when surface species colonise subterranean habitats. This project focuses on the evolution of Heat Shock protein (Hsp) genes that play critical roles in adaptation to environmental stress and the process of de-canalisation, the release of cryptic genetic variation that can allow novel morphologies to evolve in new environments. The project expects to provide further understanding of how species may potentially adapt to environmental stresses in the future, including climate change.Read moreRead less
Is regressive evolution associated with loss of gene function in subterranean animals? This project aims to investigate a fundamental biological process: the evolutionary basis for how non-functional characters, such as eyes in subterranean animals, are lost. It will use a unique model system based on eyeless water beetles, and utilise novel new genomic tools to test whether loss of characters results from gene inactivation.
How are visual gene pathways lost and restored during reptile evolution? This project aims to investigate how complex traits are lost during evolution, and once lost if they can be regained. The project will use the diverse visual systems of snakes and lizards to shed light on the process of gene loss in degenerative lineages, and discover the mechanisms that compensate for gene losses in taxa with secondarily evolved visual capabilities- providing a case of evolutionary re-innovation in complex ....How are visual gene pathways lost and restored during reptile evolution?

Building Central Asia: Linking the Growth of Asia to its Exhumation. The consumption of the Tethys Ocean and the associated collision of Gondwana-derived terranes with Eurasia resulted in the uplift of the highest mountain belt on Earth: the Himalayas. However, stresses from this collision zone propagated far into the Eurasian interior by reactivating faults and creating mountain belts along these fault zones. This project aims to map and model how and when fault (re)activation occurred by integ ....Building Central Asia: Linking the Growth of Asia to its Exhumation. The consumption of the Tethys Ocean and the associated collision of Gondwana-derived terranes with Eurasia resulted in the uplift of the highest mountain belt on Earth: the Himalayas. However, stresses from this collision zone propagated far into the Eurasian interior by reactivating faults and creating mountain belts along these fault zones. This project aims to map and model how and when fault (re)activation occurred by integrating multi-method thermochronological and structural data on major Meso-Cenozoic Central Asian fault systems. The resulting time-integrated tectonic model will aid in the understanding of the India-Eurasia collision, the building of the mountainous Central Asian landscape and its influence on the Asian climate.Read moreRead less
What is the function of gamma-aminobutyric acid-gated anion channels in plants? The project will identify the molecular basis of gamma-aminobutyric acid (GABA) signalling in plants. This is significant because GABA regulates proteins that release molecules involved in root-soil interactions, growth, and fertilisation. The project's discoveries will allow improvement of these agronomic traits that ultimately determine crop yield.
A signalling pathway for future crop improvement. This project aims to decipher a mechanism that controls plant gas exchange – the process that emits oxygen, loses water, absorbs carbon dioxide and is essential for plant growth for food, fibre and fuel production. When plants encounter stressful conditions such as drought, high temperatures or flooding, they adapt their physiology to maintain viability and re-establish growth. This project will manipulate stress-induced gamma-aminobutyric acid’s ....A signalling pathway for future crop improvement. This project aims to decipher a mechanism that controls plant gas exchange – the process that emits oxygen, loses water, absorbs carbon dioxide and is essential for plant growth for food, fibre and fuel production. When plants encounter stressful conditions such as drought, high temperatures or flooding, they adapt their physiology to maintain viability and re-establish growth. This project will manipulate stress-induced gamma-aminobutyric acid’s capacity to control plant gas exchange to help secure future food production, through improving crop tolerance to stresses such as low water availability and high temperatures – conditions associated with a changing Australian climate.Read moreRead less
Control of crop-microbe symbiosis by new plant hormones. This project aims to discover how plants use hormone-like chemicals, called butenolides, to control symbiotic relationships with soil fungi. It will use multidisciplinary and collaborative techniques to establish how butenolide metabolism affects the diversity of fungal colonisation. Expected outcomes of this project include a deeper understanding of how plants regulate the competency of roots to host symbiotic fungi, and how this affects ....Control of crop-microbe symbiosis by new plant hormones. This project aims to discover how plants use hormone-like chemicals, called butenolides, to control symbiotic relationships with soil fungi. It will use multidisciplinary and collaborative techniques to establish how butenolide metabolism affects the diversity of fungal colonisation. Expected outcomes of this project include a deeper understanding of how plants regulate the competency of roots to host symbiotic fungi, and how this affects plant growth. As such, it will generate knowledge of how cereals such as barley could be modified to improve their nutrient use efficiency. Benefits of this project include the potential to reduce fertiliser inputs, thereby improving the competitiveness and environmental impact of Australian agriculture.Read moreRead less
