This project will increase understanding of physiological and molecular mechanisms that enable widespread beneficial symbiotic soil fungi to influence plant productivity and biodiversity of natural and managed plant ecosystems. It will also aid biotechnological and agronomic goals of maximizing use of scarce soil nutrients, especially phosphate. Results will be important for agro-industry and Government groups focusing on 'healthy soil'. The project adds considerably to investment in research, infrastructure and international collaboration in this priority area. It will enhance Australia's reputation for research in soil biology and provide high standards in research education and training in an internationally recognised environment.Read moreRead less
Using defined biotic and abiotic stimuli to dissect patterns of gene expression and protein accumulation that specify root architecture. Root morphogenesis is fundamental to agriculture and valuable for investigating the informational networks of genes, proteins and metabolites that control root growth and plant development. Root systems vary widely both within and between species. Root morphology is directed by a basic genetic program that is influenced by environmental factors to provide an e ....Using defined biotic and abiotic stimuli to dissect patterns of gene expression and protein accumulation that specify root architecture. Root morphogenesis is fundamental to agriculture and valuable for investigating the informational networks of genes, proteins and metabolites that control root growth and plant development. Root systems vary widely both within and between species. Root morphology is directed by a basic genetic program that is influenced by environmental factors to provide an enormous "phenotypic plasticity". This project will use two model plant systems to investigate how different external signals are "translated" by the plant into different developmental regimes. This knowledge is crucial to understanding how the plasticity of root development is modulated in response to changing environmental factors.Read moreRead less
Biofertiliser technology for improved yields and environmental sustainability of rice and wheat crops. Australia faces the double challenge of improving the efficiency of its crop production while minimising the agricultural impact on its fragile biodiversity. Our project will meet this challenge by providing the technology for using natural biofertilisers in cereal crops.

Australia faces the double challenge of improving the efficiency of its crop production while minimising the agricultural impact on its fragile biodiversity. Our project will meet this challenge by providing the technology for using natural biofertilisers in cereal crops. This will reduce our heavy reliance on chemical fertilisers - with associated soil loss, salinity and acidity, and high demand on scarce water resources - and significantly increase our crop yields. Our advances will help Australian farmers to reduce the costs and increase the productivity of our substantial export crops while improving their environmental sustainability.Read moreRead less

This project will deliver efficient use of the limited supplies of high quality phosphorus minerals as fertiliser-P, simultaneously acting to reverse and prevent soil acidification. These cost-effective benefits from utilising Australia's microbial biodiversity will have major economic and environmental impacts in rural Australia,increasing the profitability of farming and reducing the potential for contamination of aquatic systems and groundwater with nutrients causing algal blooms. By solving needs for fertiliser-P while preventing acidification of soil, farmers are expected to welcome this novel fertiliser technology.Read moreRead less
How does warming prevent soil nitrogen availability from declining in response to elevated CO2? The sustainable use of the terrestrial environment depends upon maintaining ecosystem productivity which in turn depends upon nutrient availability within the soil. Increasing levels of CO2 in the atmosphere are known to decrease nutrient availability while warming prevents this from happening. The aims of this project are to determine how warming is able to prevent elevated CO2 concentrations from re ....How does warming prevent soil nitrogen availability from declining in response to elevated CO2? The sustainable use of the terrestrial environment depends upon maintaining ecosystem productivity which in turn depends upon nutrient availability within the soil. Increasing levels of CO2 in the atmosphere are known to decrease nutrient availability while warming prevents this from happening. The aims of this project are to determine how warming is able to prevent elevated CO2 concentrations from reducing soil N availability and hence productivity in a native grassland ecosystems. This is important, as it will allow likely problems caused by global climate change to be predicted by increasing the understanding of the underlying mechanisms as well as improving the management of grasslands in an environmentally sustainable way.

The Western Australian Small Animal Imaging facility will provide wide access for the West Australian research community to a multimodality functional and dynamic core bioimaging facility to characterise in-vivo animal models, including extensive postgraduate research training. Wide-ranging research outcomes of national and community benefit include imaging tumour development, bone metabolism (osteoporosis), neural function (Alzheimer's disease) and regeneration, and infection mechanisms in live animals, which will result in improvements in human health. Imaging and monitoring coral growth, fish age, and soil structure will improve the economics and sustainability of Australia's marine ecosystems and agricultural food production.Read moreRead less
Mechanisms of arsenic tolerance in plants: how do symbiotic arbuscular mycorrhizal (AM) fungi reduce uptake? Arsenic contamination of soil is a major problem caused by irrigation with contaminated ground-water, mining and application of pesticides. Plant uptake leads to entry into food chains, with severe consequences for crop growth and human health. This project will aid the search for mechanisms to reduce plant arsenic accumulation by exploring roles of beneficial plant-fungus symbioses in r ....Mechanisms of arsenic tolerance in plants: how do symbiotic arbuscular mycorrhizal (AM) fungi reduce uptake? Arsenic contamination of soil is a major problem caused by irrigation with contaminated ground-water, mining and application of pesticides. Plant uptake leads to entry into food chains, with severe consequences for crop growth and human health. This project will aid the search for mechanisms to reduce plant arsenic accumulation by exploring roles of beneficial plant-fungus symbioses in reducing uptake. Results will be relevant to most crop plants, because of the widespread occurrence of the symbioses. The project will enhance collaboration with China where arsenic toxicity is prevalent, provide education and training in an internationally recognised laboratory and enhance Australia's reputation for tackling soil contamination.Read moreRead less

Plant-microbial interactions can increase vegetative growth and crop yield. These PGPR effects result from improved N and P nutrition, stimulation of root growth, disease control, altered environmental conditions and, most importantly, positive interactions between all these. This project aims to develop plant growth promoting bacteria and fungi as commercial products. By matching microbes to plants and soil environments, a set of peat-based inoculants will be optimised for application as biofertilisers to field crops and turfgrass.
Potential applications are both rural and urban.
The outcomes will be proven commercial products able to promote plant growth and rapid recovery from adverse conditions.Read moreRead less
