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
Defining pathways that establish and maintain reproductive cell identity in plant ovules and seeds. Unlike animals, individual somatic cells in plants have the remarkable ability to regenerate into new plants, depending on the signals they perceive. This developmental plasticity is particularly important during normal plant growth, when mature cells adopt new identities within multicellular environments. Tissue complexity is critical for the utilisation of plants in society as food, fuel and fib ....Defining pathways that establish and maintain reproductive cell identity in plant ovules and seeds. Unlike animals, individual somatic cells in plants have the remarkable ability to regenerate into new plants, depending on the signals they perceive. This developmental plasticity is particularly important during normal plant growth, when mature cells adopt new identities within multicellular environments. Tissue complexity is critical for the utilisation of plants in society as food, fuel and fibre, but how and why plant cells adopt or change identity has been difficult to determine. This project aims to employ next-generation molecular methods to identify pathways driving differentiation of specific ovule and seed cell-types, which directly impact crop quality, yield and end-use.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
Factors causing wheat stripe rust epidemics. This project aims to tackle wheat stripe rust, one of the most important fungal diseases of wheat in Australia, causing losses of up to $125 million a year. This project expects to gain insights into the fungal evolution and the molecular mechanism that causes hyper-virulent pathogen isolates. The expected outcome is to identify and characterise multiple genetic factors in the pathogen that contribute to wheat stripe rust epidemics in Australia. This ....Factors causing wheat stripe rust epidemics. This project aims to tackle wheat stripe rust, one of the most important fungal diseases of wheat in Australia, causing losses of up to $125 million a year. This project expects to gain insights into the fungal evolution and the molecular mechanism that causes hyper-virulent pathogen isolates. The expected outcome is to identify and characterise multiple genetic factors in the pathogen that contribute to wheat stripe rust epidemics in Australia. This project will contribute to improved disease management strategies to contain wheat stripe rust, resulting in higher wheat yields, reduced application of fungicides and increased revenue for Australian wheat farmers.Read moreRead less
Deciphering the genetic regulation of inflorescence development in wheat. The project aims to identify genes and molecular processes that regulate inflorescence architecture in wheat, using state-of-the-art genetic resources to identify novel biological mechanisms that regulate the development of spikelets – reproductive branches that contain grain-producing florets. The research is highly significant as little is known about how spikelet and floret numbers are determined genetically in wheat, a ....Deciphering the genetic regulation of inflorescence development in wheat. The project aims to identify genes and molecular processes that regulate inflorescence architecture in wheat, using state-of-the-art genetic resources to identify novel biological mechanisms that regulate the development of spikelets – reproductive branches that contain grain-producing florets. The research is highly significant as little is known about how spikelet and floret numbers are determined genetically in wheat, and new traits need to be identified to increase yields for the world’s growing population. Project outcomes will include new insights into the biology that underpins grain production of wheat, with expected benefits enabling sustainable increases of yields by breeders and growers to help bolster global food security.Read moreRead less
The identification of Mycosphaerella graminicola effectors that promote pathogenicity on wheat. Fungal diseases are one of the greatest challenges to sustainable wheat production in the 21st century. Septoria tritici blotch is one such disease as it inflicts millions of tonnes in yield losses per annum. This project will identify the molecular basis of Septoria tritici blotch and assess its potential as an Australian biosecurity threat.
