Understanding the control of male germ-line development by the germline-restrictive silencing factor in plants. The world population is currently increasing at an unprecedented rate, with a concomitant requirement to double the food production from the same amount of arable land. To ensure global political and social stability, equitably increasing sustainable food production without compromising environmental integrity remains a major challenge. This proposal investigates the molecular mechanis ....Understanding the control of male germ-line development by the germline-restrictive silencing factor in plants. The world population is currently increasing at an unprecedented rate, with a concomitant requirement to double the food production from the same amount of arable land. To ensure global political and social stability, equitably increasing sustainable food production without compromising environmental integrity remains a major challenge. This proposal investigates the molecular mechanisms underlying male germ line initiation and development in plants. Switching off male gamete development in some crop plants will create male sterile lines, which, when crossed with genetically distinct lines, will have the potential to produce hybrids that yield 20-30 percent more crop without additional inputs.

Epigenetic programming of plant sperm cells. Most of the grains and seeds that form the world's food supply are the result of the successful functioning of sperm and egg cells during fertilisation. This proposal aims to investigate the nature of sperm cell genome programming in plants and unravel molecular processes that give these cells their unique identity. This innovative and challenging research will also provide an excellent opportunity for training the next generation of scientists. The o ....Epigenetic programming of plant sperm cells.

This proposal aims to investigate the nature of sperm cell genome programming in plants and unravel molecular processes that give these cells their unique identity. This innovative and challenging research will also provide an excellent opportunity for training the next generation of scientists. The outcomes of this proposal will enhance Australia's international lead in this field and will pave the way toward the development of new approaches for sustaining and enhancing crop productivity under changing environmental conditions.

Protecting the Australian chickpea industry through knowledge of the current Ascochyta rabiei fungal population and risk to resistance breeding strategies. Australian chickpea is highly vulnerable to epidemics of Ascochyta blight, which may cause total crop failure. This project will help to maintain Australia's position as a major global chickpea producer through maximising the life span of current resistance genes to A. rabiei. and determining the applicability of other potential resistance so ....Protecting the Australian chickpea industry through knowledge of the current Ascochyta rabiei fungal population and risk to resistance breeding strategies. Australian chickpea is highly vulnerable to epidemics of Ascochyta blight, which may cause total crop failure. This project will help to maintain Australia's position as a major global chickpea producer through maximising the life span of current resistance genes to A. rabiei. and determining the applicability of other potential resistance sources. The knowledge that will be generated regarding the pathogen's potential to overcome host resistance is imperative for developing future disease management strategies, especially since more aggressive isolates exist outside Australia. The project findings will feed directly into the National Australian Chickpea Breeding Program.Read moreRead less

Summary
The Insect-Plant Chemical Ecology Network (IPCEN). We bring together plant molecular biology, entomology and analytical chemistry to transform three leading fields of Australian research into an advanced science with far reaching capabilities in innovative research and applied outcomes. Expertise studying the biochemical pathways that produce specific plant compounds and expertise in insect recognition and response to these chemicals will be brought together. This will lead to new research outco ....The Insect-Plant Chemical Ecology Network (IPCEN). We bring together plant molecular biology, entomology and analytical chemistry to transform three leading fields of Australian research into an advanced science with far reaching capabilities in innovative research and applied outcomes. Expertise studying the biochemical pathways that produce specific plant compounds and expertise in insect recognition and response to these chemicals will be brought together. This will lead to new research outcomes and solutions to problems in agriculture, horticulture, forestry and protection of Australia's native flora. Researchers are struggling to create these links, constrained by disciplinary boundaries and geographical isolation. Key industries and researchers already support this proposal.Read moreRead less
Functional and regulatory analysis of n-acetylcholine receptors, key targets of insecticides. Agriculture is one of Australia's mainstay industries and a major user of insecticides. However, current insecticides suffer a number of significant deficiencies, including collateral damage in the environment and insect resistance. One of the major targets for insecticides are a class of neuronal receptors, found in organisms ranging from worms to man. Our work will provide a detailed biological unders ....Functional and regulatory analysis of n-acetylcholine receptors, key targets of insecticides. Agriculture is one of Australia's mainstay industries and a major user of insecticides. However, current insecticides suffer a number of significant deficiencies, including collateral damage in the environment and insect resistance. One of the major targets for insecticides are a class of neuronal receptors, found in organisms ranging from worms to man. Our work will provide a detailed biological understanding of these receptors leading to better ways of developing new insecticides. Similar receptors in humans are the target for nicotine and associated with neurological disorders such as schizophrenia and autism. Thus our work will also increase our understanding of important human receptors associated with disease.Read moreRead less
A novel link between plant pathogen defence and DNA repair capability. 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.

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.
