Co-evolution of the host pathogen interaction between Leptosphaeria maculans and Brassica species. Brassica canola is Australia's third largest export crop, producing 13% of the world's canola oil. However, blackleg disease, caused by the fungus Leptospheria maculans leads to annual yield losses of 15%, with 100% loss associated with breakdown of resistance. International investment has provided novel genome resources for Brassica and L. maculans. Applying these resources to understand the co-ev ....Co-evolution of the host pathogen interaction between Leptosphaeria maculans and Brassica species. Brassica canola is Australia's third largest export crop, producing 13% of the world's canola oil. However, blackleg disease, caused by the fungus Leptospheria maculans leads to annual yield losses of 15%, with 100% loss associated with breakdown of resistance. International investment has provided novel genome resources for Brassica and L. maculans. Applying these resources to understand the co-evolution of this plant-fungal interaction could prevent the current boom-bust cycle of canola production in Australia. This study will also provide a model and knowledge base for applications in other species, leading to enhanced crops with increased plant protection and robust, reliable productivity.Read moreRead less
Improved seasonal rainfall prediction for grain growers using farm level data and novel modelling. Successful grain production, a key export commodity for Australia, depends heavily on reliable seasonal forecasts. However, the highly variable climate means that for Australia’s 25,000 grain growers current forecasts lack detail in space and time. Using a combination of fuzzy classification and artificial neural networks, this project will develop a locally detailed continuously updating data-driv ....Improved seasonal rainfall prediction for grain growers using farm level data and novel modelling. Successful grain production, a key export commodity for Australia, depends heavily on reliable seasonal forecasts. However, the highly variable climate means that for Australia’s 25,000 grain growers current forecasts lack detail in space and time. Using a combination of fuzzy classification and artificial neural networks, this project will develop a locally detailed continuously updating data-driven seasonal forecast system using high density climate data from the 17,000 Grain Growers Association members and climate drivers such as sea surface temperature from the Bureau of Meteorology. After validation against observed data, the forecasts will be delivered via a web-based portal to users.Read moreRead less
Regulation of Plant Development by Small RNAs. Understanding the roles of small RNAs and their pathways is a new field of research that is giving, and will continue to give profound insights into how multicellular organisms regulate gene expression at a genomic level. Research in this area has already led to RNA interference technology, by which almost any gene can be switched off, and there is considerable potential for other gene silencing and trait modification technologies to emerge.

Genome Approaches to Investigate Metabolic Coordination in Plant Cells. Metabolism of C and N in legume nodules requires interaction between the symbiotic bacteria and plant organelles, particularly metabolism in plastids and mitochondria. Fixed N is assimilated through the de novo synthesis of purines in both plastids and mitochondria. However, each of the nine pathway enzymes is encoded by a single gene, indicating each protein is targeted to both organelles. Purine metabolism will provide ....Genome Approaches to Investigate Metabolic Coordination in Plant Cells. Metabolism of C and N in legume nodules requires interaction between the symbiotic bacteria and plant organelles, particularly metabolism in plastids and mitochondria. Fixed N is assimilated through the de novo synthesis of purines in both plastids and mitochondria. However, each of the nine pathway enzymes is encoded by a single gene, indicating each protein is targeted to both organelles. Purine metabolism will provide a model to assess the more general occurrence of dual-targeted proteins in plants. The aim is to identify and eventually exploit the signalling mechanism(s) that mediate communication between plastids and mitochondria.Read moreRead less

Plants and plant-based industries are essential for the provision of food, clothing and building materials and underpin the economies of rural communities. Plant yield and quality and the biodiversity of natural systems are dramatically reduced by disease. The fundamental knowledge gained from our research will enable manipulation of the factors that enhance disease resistance resulting in a significant benefit to Australian agriculture and protection of our natural resources. The current reliance for disease control on chemicals that damage the environment will be reduced and our research will contribute directly to the provision of cheaper, simpler and more effective methods of control.

Plant Protein Signalling Networks. We will assess the functional role of PNPs (novel plant protein hormones) at a biochemical, molecular and cellular level. Importantly, as stresses from climatic extremes are increasing, this will lead to new insights and critical appreciation of the processes plants use to regulate their water status.

We will assess the functional role of PNPs (novel plant protein hormones) at a biochemical, molecular and cellular level. Importantly, as stresses from climatic extremes are increasing, this will lead to new insights and critical appreciation of the processes plants use to regulate their water status. Since water and solute status underpins the regulation of plant growth and development, these findings will have a major impact on both agriculture and horticulture in Australia. The new insights that we gain can be used to directly accelerate progress towards the development of plants with improved drought and salinity tolerance that will lead to better crop and pasture productivity under harsh Australian conditions.Read moreRead less

Discovery of the molecular mode of action of karrikins in plants. Karrikins are a newly-discovered family of naturally-occurring plant growth regulators that stimulate seed germination and seedling vigour. They were discovered in smoke and while they are centrally important in fire ecology they have far wider significance since species from non-fire-prone regions also respond to karrikins. Our research will discover how karrikins work at the molecular level in plant cells. Our discoveries will b ....Discovery of the molecular mode of action of karrikins in plants. Karrikins are a newly-discovered family of naturally-occurring plant growth regulators that stimulate seed germination and seedling vigour. They were discovered in smoke and while they are centrally important in fire ecology they have far wider significance since species from non-fire-prone regions also respond to karrikins. Our research will discover how karrikins work at the molecular level in plant cells. Our discoveries will be applied to improve growth of crop plants, to stimulate germination of weeds so that they can be eradicated, and in restoration ecology to revegetate degraded land such as minesites. Australia's world-leading position in this new important research area will be enhanced.Read moreRead less
