Genetics of species differentiation and hybridisation in Eucalyptus. This project aims to use state-of-the-art genomic technologies to characterise genes and genomic regions important for speciation and adaptation in Australia’s iconic eucalypts, and study the importance of hybridisation between species, especially during range expansion and contraction. A major international effort has seen a eucalypt become the second forest tree genome sequenced.

This project aims to use state-of-the-art genomic technologies to characterise genes and genomic regions important for speciation and adaptation in Australia’s iconic eucalypts, and study the importance of hybridisation between species, especially during range expansion and contraction. A major international effort has seen a eucalypt become the second forest tree genome sequenced. This project aims to link the expanding international knowledge on the eucalypt genome to the evolutionary dynamics of wild populations in Australia to provide unprecedented insights into the nature of species and processes which have shaped their evolution. These insights may inform their breeding as well as their conservation and management in Australia.Read moreRead less
The genetics of adaptation: changing developmental trajectories in eucalypts. During their life cycles, many animals and plants undergo genetically programmed changes in form. Such changes may be dramatic and rapid as seen in insect metamorphoses or plant heteroblasty, and may have ecological, evolutionary and even economic consequences. The project aims to identify the genes controlling such transitions in Australia's eucalypts.
How plants open up: revealing the evolution of stomatal opening mechanisms. This project aims to identify novel and conserved mechanisms that drive the opening of stomata – plant pores that enable CO2 acquisition for photosynthesis. Stomatal movements strongly affect plant productivity and water use efficiency and have profoundly influenced the earth’s climate and terrestrial ecology. This project will address critical gaps in our understanding of how plants open stomata in response to their env ....How plants open up: revealing the evolution of stomatal opening mechanisms. This project aims to identify novel and conserved mechanisms that drive the opening of stomata – plant pores that enable CO2 acquisition for photosynthesis. Stomatal movements strongly affect plant productivity and water use efficiency and have profoundly influenced the earth’s climate and terrestrial ecology. This project will address critical gaps in our understanding of how plants open stomata in response to their environment and the evolutionary history of the genes controlling this fundamental process. A major expected outcome is knowledge of the diversity of stomatal opening pathways, which should ultimately lead to improved predictions of plant responses to environmental change and assist future targeted modification of plant growth.Read moreRead less

Summary
The quick and the dead: identifying mechanisms for plant drought survival. This project aims to identify genes that control plant responses to low air humidity, which enhance drought survival by restricting water loss. Most plant water loss occurs through pores called stomata. This project expects to identify the genes that close stomata within minutes of decreased humidity by determining the molecular changes that occur over this timeframe and testing candidate genes for a critical role. Divers ....The quick and the dead: identifying mechanisms for plant drought survival. This project aims to identify genes that control plant responses to low air humidity, which enhance drought survival by restricting water loss. Most plant water loss occurs through pores called stomata. This project expects to identify the genes that close stomata within minutes of decreased humidity by determining the molecular changes that occur over this timeframe and testing candidate genes for a critical role. Diverse land plant models will be examined to ensure broad applicability of results. A major expected outcome is new knowledge of genes that minimise plant water loss, which would ultimately benefit plant-based industries through new targets for breeding improved, drought-adapted varieties for food security in a drying climate.Read moreRead less
Natural selection and the Tasmanian devil. This project aims to explain evolution of immune capabilities in response to disease threats in the wild by assessing the immune adaptive capabilities of Tasmanian devils in response to facial tumour disease. It plans to determine how the expression of immune genes differs between wild and captive populations. The project will combine immunology, epidemiology and evolutionary biology, to understand the role of host genetic and phenotypic adaptations to ....Natural selection and the Tasmanian devil. This project aims to explain evolution of immune capabilities in response to disease threats in the wild by assessing the immune adaptive capabilities of Tasmanian devils in response to facial tumour disease. It plans to determine how the expression of immune genes differs between wild and captive populations. The project will combine immunology, epidemiology and evolutionary biology, to understand the role of host genetic and phenotypic adaptations to disease threats. The project will assist in the development of diagnostic tools for managing this and other threatened species and for screening disease resistance markers across wild and captive insurance populations.Read moreRead less
Providing a genetic framework to enhance the success and benefits from forest restoration and carbon plantings in rural landscapes. This project will provide a genetic framework to inform strategies for climate change adaptation in forest restoration and carbon plantings in Australia. Key questions to be addressed include the value of local versus non-local seed sources and the role of tree genetics in shaping biodiversity and other ecosystem services.
