Insects have a cunning ability to respond to damaging environments by evolving genetic resistance or mobilising metabolic tolerance mechanisms. Recent observations of inducible tolerance to synthetic and biopesticides, which can be transmitted to offspring by a maternal effect has the potential to cause ecological and economic problems in agricultural production. We will use field-collected Diamondback moth (DBM), a major insect pest in canola and brassica vegetable crops, to investigate the genetic implications of inducible tolerance for the integrated management of DBM and for the design of new resistance management strategies.Read moreRead less
Unique plant hormone responses: the key to nitrogen-fixing nodules. This project aims to build a model of the signals that regulate root nodule formation, unique root organs formed by some plants that host nitrogen-fixing bacteria. Nitrogen is often limited in the soil and agriculture relies on nitrogen fertiliser. Sustainable sources of plant nutrients are required to ensure food security and minimise the environmental impact of intensive farming. This project will provide fundamental informati ....Unique plant hormone responses: the key to nitrogen-fixing nodules. This project aims to build a model of the signals that regulate root nodule formation, unique root organs formed by some plants that host nitrogen-fixing bacteria. Nitrogen is often limited in the soil and agriculture relies on nitrogen fertiliser. Sustainable sources of plant nutrients are required to ensure food security and minimise the environmental impact of intensive farming. This project will provide fundamental information on why some species can form nitrogen-fixing nodules by examining the role of plant hormones. This will build the knowledge base required to potentially expand this symbiosis into non-legumes, harnessing the huge advantage nodule forming species have in staple crops.Read moreRead less
Isolation and characterization of cell signalling systems that activate or suppress apoptosis in pathogenic and symbiotic fungal:plant interactions. The key roles of programmed cell death (PCD) in plant disease are becoming apparent. This project will test the hypotheses that successful colonisation by arbuscular mycorrhizae in plant roots requires the plant to up-regulate inhibitors of PCD; that susceptibility in plants to necrotrophic fungal pathogens requires triggering of PCD; and that resis ....Isolation and characterization of cell signalling systems that activate or suppress apoptosis in pathogenic and symbiotic fungal:plant interactions. The key roles of programmed cell death (PCD) in plant disease are becoming apparent. This project will test the hypotheses that successful colonisation by arbuscular mycorrhizae in plant roots requires the plant to up-regulate inhibitors of PCD; that susceptibility in plants to necrotrophic fungal pathogens requires triggering of PCD; and that resistance is the result of activation of inhibitors of PCD. This international project will have important implications biologically and economically for control of plant disease and symbiosis, will train early career researchers in an area of international expertise and will strengthen collaboration between the US and Australian research groupRead moreRead less
Genetic control of flowering in legumes. Flowering in plants is strongly regulated by environmental factors, with important consequences for their natural distribution and use in agriculture. This project will isolate genes, characterize genetic diversity and dissect molecular mechanisms that regulate flowering, contributing to fundamental biology, crop improvement and research training.

Summary
Specialised greenhouse space for new initiatives. This greenhouse facility will enable fundamental research of nutrient transport in fruits, seeds and fibre and will underpin biotechnological advances to improve crop yield and quality. The development of drought tolerant Sorghum as a dedicated bio-energy crop will reduce dependence on fossil fuels, building towards an environmentally sustainable Australia.
