Targeting the genome and epigenome of the exercising skeletal muscle. This project aims is to discover epigenetic and genetic biomarkers that predict fitness changes, following exercise intervention. Individuals are remarkably variable in their responses to exercise interventions, and a large portion of these responses is attributed to genetics, and epigenetics (the effect of the environment on the expression of genes). Using controlled exercise training as a model, this project expects to disco ....Targeting the genome and epigenome of the exercising skeletal muscle. This project aims is to discover epigenetic and genetic biomarkers that predict fitness changes, following exercise intervention. Individuals are remarkably variable in their responses to exercise interventions, and a large portion of these responses is attributed to genetics, and epigenetics (the effect of the environment on the expression of genes). Using controlled exercise training as a model, this project expects to discover epigenetic and genomic markers in skeletal muscle predictive of exercise adaptations. This will contribute to the development and future delivery of targeted and personalised exercise programs for the general population. This has important implications for improving health in the Australian population.Read moreRead less

Mechanisms of zinc transport and homeostasis in plants. Zinc deficiency is a widespread factor limiting crop production and affects many soils of southern Australia and around the world. Genetic techniques can be used to identify zinc-efficient crop breeds able to grow well under zinc deficient conditions and able to efficiently deliver zinc to cereal grains to alleviate nutritional zinc-deficiency in humans. This project will identify new genes important in zinc transport and homeostasis in pla ....Mechanisms of zinc transport and homeostasis in plants. Zinc deficiency is a widespread factor limiting crop production and affects many soils of southern Australia and around the world. Genetic techniques can be used to identify zinc-efficient crop breeds able to grow well under zinc deficient conditions and able to efficiently deliver zinc to cereal grains to alleviate nutritional zinc-deficiency in humans. This project will identify new genes important in zinc transport and homeostasis in plants and will ultimately allow their role in zinc efficient crops to be assessed. This will contribute to more rapid and directed strategies in breeding zinc efficient crops.Read moreRead less
Long noncoding RNAs and their regulatory roles in epigenetic control of gene expression in plants. Epigenetic control of gene expression plays a critical role in development, environmental adaptation, stress response and disease resistance in plants, but its molecular basis remains largely unknown. The proposed study should contribute to the emerging field of epigenetics by discovering new regulatory noncoding RNAs involved in epigenetic mechanisms in plants. These new discoveries could potentia ....Long noncoding RNAs and their regulatory roles in epigenetic control of gene expression in plants. Epigenetic control of gene expression plays a critical role in development, environmental adaptation, stress response and disease resistance in plants, but its molecular basis remains largely unknown. The proposed study should contribute to the emerging field of epigenetics by discovering new regulatory noncoding RNAs involved in epigenetic mechanisms in plants. These new discoveries could potentially provide new opportunities and platforms for improving the performance, yield and quality of crop plants. The proposed study is therefore consistent with the national research priority goals such as breakthrough science, frontier technologies and promoting an innovation culture.Read moreRead less
Controlling the rate of transcription and translation of Rubisco transgenes effectively in higher-plant plastids. Genetic transformation of the circular genome of the plastids provides a containable means for modifying plant growth by manipulating photosynthesis. Although the transformation mechanism is precise, predicting the level of foreign gene expression is difficult because the amounts of messenger RNA and protein produced by foreign genes in plastids varies widely, even when the protein a ....Controlling the rate of transcription and translation of Rubisco transgenes effectively in higher-plant plastids. Genetic transformation of the circular genome of the plastids provides a containable means for modifying plant growth by manipulating photosynthesis. Although the transformation mechanism is precise, predicting the level of foreign gene expression is difficult because the amounts of messenger RNA and protein produced by foreign genes in plastids varies widely, even when the protein assembles without difficulty. This project will devise strategies for controlling this variability that will facilitate attempts to exploit plastid transformation for transplanting better versions of the photosynthetic CO2-fixing enzyme, Rubisco, into plants to improve their growth efficiency in terms of water, fertiliser and light use.Read moreRead less

Plant genomics has direct benefit to crop improvement, especially as focussed in the applicants' laboratories. Thus, the Australian agri-food sector will benefit substantially from the acceleration in plant functional genomics that will arise from the installation of the robotics equipment described in the current application, by both underpinning more applied research and also being used directly in crop improvement programs such as are based at the Waite Campus. The outputs will include crops with increased tolerance to biotic and abiotic stresses, a reduced dependence on chemical inputs such as fertilisers and improved food quality, with consequent benefits to the environment and human health and nutrition.Read moreRead less
Beyond the gene: Linking herbivore behaviour to plant defense gene expression. This collaborative project investigates insect herbivore avoidance of plant defence mechanisms. Our project is novel because it integrates changes in the plant at a number of different levels and links them to insect foraging behaviour. Researchers assume that insects respond to plant defences by changing their foraging behaviour. This has not been tested directly. We use the genetically well characterised plant Arabi ....Beyond the gene: Linking herbivore behaviour to plant defense gene expression. This collaborative project investigates insect herbivore avoidance of plant defence mechanisms. Our project is novel because it integrates changes in the plant at a number of different levels and links them to insect foraging behaviour. Researchers assume that insects respond to plant defences by changing their foraging behaviour. This has not been tested directly. We use the genetically well characterised plant Arabidopsis and the world-wide pest Helicoverpa (heliothis) as a model system. Damage caused to crops by insect herbivores is a direct function of behaviour. Understanding this behaviour will lead to improved pest management and reduced economic losses.Read moreRead less
The co-expression of visual pigments in a single photoreceptor: environmental regulation and spectral tuning. The light sensitive cells (photoreceptors) in the vertebrate retina contain filters (oil droplets) and visual pigments (opsins). These structures tune the incoming light and initiate the visual process, respectively. Exciting new research reveals that some vertebrates express more than one opsin within a single photoreceptor. We plan to examine the regulation of single and two co-express ....The co-expression of visual pigments in a single photoreceptor: environmental regulation and spectral tuning. The light sensitive cells (photoreceptors) in the vertebrate retina contain filters (oil droplets) and visual pigments (opsins). These structures tune the incoming light and initiate the visual process, respectively. Exciting new research reveals that some vertebrates express more than one opsin within a single photoreceptor. We plan to examine the regulation of single and two co-expressed opsin genes by manipulating the light environment. We expect to determine the environmental triggers for visual pigment tuning and the effects of co-expression on colour vision.Read moreRead less
Environmental regulation of opsin expression and spectral tuning in the vertebrate retina. Exciting new evidence shows that the vertebrate visual system is extraordinarily plastic and that the colour and brightness of the ambient light regulates both the spatial and temporal expression of visual pigments (opsin) genes and the degree of spectral filtering in the retina. Based on findings that more than one visual pigment can be co-expressed in a single photoreceptor type, we plan to manipulate th ....Environmental regulation of opsin expression and spectral tuning in the vertebrate retina. Exciting new evidence shows that the vertebrate visual system is extraordinarily plastic and that the colour and brightness of the ambient light regulates both the spatial and temporal expression of visual pigments (opsin) genes and the degree of spectral filtering in the retina. Based on findings that more than one visual pigment can be co-expressed in a single photoreceptor type, we plan to manipulate the light environment in order to identify and quantify the effect of different lighting regimes by morphological, spectral and molecular techniques in a concerted effort to understand the regulation of opsin expression.Read moreRead less
