Novel laser isotopic techniques to assess the potential for water-use efficiency improvement of Australian crops. This project aims to develop new methods to reduce the water used by grain crops while maintaining productivity by advancing knowledge of the regulation plant carbon gain and water loss. Novel laser-lased measurement systems developed and applied in this project will provide new mechanistic understanding of plant carbon-water dynamics for individual leaves and at the whole crop scal ....Novel laser isotopic techniques to assess the potential for water-use efficiency improvement of Australian crops. This project aims to develop new methods to reduce the water used by grain crops while maintaining productivity by advancing knowledge of the regulation plant carbon gain and water loss. Novel laser-lased measurement systems developed and applied in this project will provide new mechanistic understanding of plant carbon-water dynamics for individual leaves and at the whole crop scale. Water availability is the most pressing environmental issue facing the Australian grain industry, so improvements in the efficiency with which water is used will have profound economic and environmental effects.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
Linking Stress Tolerance to Molecular Evolution of Grass Stomata. Salinity and drought are two detrimental environmental stresses, affecting agricultural productivity and ecosystem health in Australia and around the world. This project will focus on the evolutionary, physiological and molecular aspects of stomatal regulation between wheat, barley and their wild relatives for salinity and drought tolerance. This project will advance the scientific knowledge in the evolution of stomatal regulation ....Linking Stress Tolerance to Molecular Evolution of Grass Stomata. Salinity and drought are two detrimental environmental stresses, affecting agricultural productivity and ecosystem health in Australia and around the world. This project will focus on the evolutionary, physiological and molecular aspects of stomatal regulation between wheat, barley and their wild relatives for salinity and drought tolerance. This project will advance the scientific knowledge in the evolution of stomatal regulation in two staple crops wheat and barley. The project will also assist plant breeders with increasing crop salinity and drought tolerance for global food security.Read moreRead less
