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
Reducing environmental footprint by improving phosphorous use efficiency. While modern agriculture relies heavily on the use of phosphorous fertilizers, most of them are not used by plants and lost in runoff, resulting in a massive environmental damage through contamination of waterways (termed eutrophication). This project takes advantage of an untapped resource - a unique collection of Tibetan wild barley genotypes, to reveal key traits that confer superior phosphorus use efficiency in wild ba ....Reducing environmental footprint by improving phosphorous use efficiency. While modern agriculture relies heavily on the use of phosphorous fertilizers, most of them are not used by plants and lost in runoff, resulting in a massive environmental damage through contamination of waterways (termed eutrophication). This project takes advantage of an untapped resource - a unique collection of Tibetan wild barley genotypes, to reveal key traits that confer superior phosphorus use efficiency in wild barley and identify appropriate candidate genes and their position on chromosomes for further incorporating these traits into commercial barley cultivars. This will reduce the environmental footprint of modern agricultural practices on terrestrial and aquatic ecosystems without compromising food security.Read moreRead less
Protecting cereal grain development at high temperatures. This project aims to investigate new temperature-responsive factors that regulate cereal grain development to protect grain production under heat stress. The new research will leverage international collaborations with access to cutting-edge genetic and technological resources, and refine novel X-ray imaging techniques in Australia, to observe how temperature affects flower structure and function in barley and rice. Favourable mutations t ....Protecting cereal grain development at high temperatures. This project aims to investigate new temperature-responsive factors that regulate cereal grain development to protect grain production under heat stress. The new research will leverage international collaborations with access to cutting-edge genetic and technological resources, and refine novel X-ray imaging techniques in Australia, to observe how temperature affects flower structure and function in barley and rice. Favourable mutations that optimise plant yield and fitness will be defined and explored in other, more complex, cereals such as wheat. Expected outcomes will be fundamental breakthroughs in understanding how plants respond to, and buffer, the effects of heat to lead to translational breeding strategies that bolster grain yield.Read moreRead less
How do plant roots align nitrogen uptake to soil opportunities? Improved nitrogen use efficiency (NUE) in crop plants is required to achieve sustainable plant agriculture practices that maximise productivity while minimising nitrogen fertiliser-dependent pollution. Current high-input monoculture plant production systems suffer from poor NUE and can contribute to local and global nitrogen pollution outcomes. Improving how plants manage their nitrogen uptake will improve NUE and help support Aust ....How do plant roots align nitrogen uptake to soil opportunities? Improved nitrogen use efficiency (NUE) in crop plants is required to achieve sustainable plant agriculture practices that maximise productivity while minimising nitrogen fertiliser-dependent pollution. Current high-input monoculture plant production systems suffer from poor NUE and can contribute to local and global nitrogen pollution outcomes. Improving how plants manage their nitrogen uptake will improve NUE and help support Australian plant agriculture. This project will investigate novel technologies that re-engineer nitrate transport activity. The project will also investigate the biochemical and molecular links between nitrogen uptake on root development required for improved plant growth.Read moreRead less
Cereals and rusts: molecular interactions for plant defence, food security. This project aims to discover the fundamental molecular interactions between proteases and protease inhibitors that occur in the ongoing conflict between cereals and their rust fungal pathogens. The research combines plant pathology, genomics and functional proteomics, and is enabled by a rapidly developing experimental approach known as activity-based protein profiling. The knowledge and outcomes potentially benefit pl ....Cereals and rusts: molecular interactions for plant defence, food security. This project aims to discover the fundamental molecular interactions between proteases and protease inhibitors that occur in the ongoing conflict between cereals and their rust fungal pathogens. The research combines plant pathology, genomics and functional proteomics, and is enabled by a rapidly developing experimental approach known as activity-based protein profiling. The knowledge and outcomes potentially benefit plant breeders through significantly improved resistance of cereals to rust diseases in Australia and overseas, thereby enhancing global food security.Read moreRead less
