The knowledge and practical outcomes generated from this project will facilitate more effective restoration of degraded native ecosystems through the return of a wider range of key understorey plant taxa and more efficient use of seed supplies. Availability of a broader suite of species will increase biodiversity, improve ecosystem resilience to change, and help in the conservation and recovery of nationally threatened taxa. By increasing the range of species with horticultural potential available for commercial propagation, it will also reduce the harvest of wild flowers. More efficient production and use of seed stocks will reduce the pressure on limited seed resources from seed harvesting.Read moreRead less

Polymetallic phytoextraction applied to mine waste. Phytoextraction involves the use of hyperaccumulator plants to grow and concentrate a metal. Subsequently, the crop is harvested and the metal extracted. The aim of this research is to investigate the uptake and chemically induced uptake of heavy metals (Ni, Co, Au, Ag, Cu, Pb, Zn, Pt, Pd, Cr) by plants grown on mine tailings and mine waste materials. Outcomes will include practical methods of metal extraction that are cheap to employ where met ....Polymetallic phytoextraction applied to mine waste.

Understanding why aluminium and other trace metals are toxic to plants - the key to improving crop yield in degraded soils. Aluminium toxicity drastically reduces plant growth in acid soils, costing Australia approximately $1.5 billion per annum in lost productivity. This project will aim to identify the reasons behind the toxicities of aluminium and other metals and has the potential to increase yields in 50 per cent of Australia’s agricultural land which is acidic.

Effective molecular plant breeding for improved water productivity of sorghum would generate significant economic and social benefits for rural communities in NE Australia. There is a significant opportunity to expand the sorghum industry in the region. Despite the global financial crisis, global demand for meat continues to increase, generating strong demand from intensive livestock industries for feed grain. Price is projected to return to high levels given continuing use of major feed grains for biofuel. A 10% increase in sorghum production would add net value of $48M annually, much via employment. The scientific content of this project positions Australia at the leading edge globally in this emerging research field. Read moreRead less
Discovery of novel circular proteins in bacteria, plants and animals: applications in drug design and crop protection. The overall goal is to use innovative methods in chemistry, biochemistry and molecular biology to determine the structures and functions of several families of circular proteins that have exciting pharmaceutical and agricultural applications.

The overall goal is to use innovative methods in chemistry, biochemistry and molecular biology to determine the structures and functions of several families of circular proteins that have exciting pharmaceutical and agricultural applications. These molecules differ from conventional proteins in that they have no ends: their termini are seamlessly joined, thereby making them exceptionally stable and resistant to enzyme digestion. The big question is ?How and why does Nature produce circular proteins?" Increasing our knowledge of why circular proteins have evolved will facilitate their applications in drug design and in the development of novel insecticides.Read moreRead less
Australia's native sorghums: a model for testing plant adaptation theories. This proposal tests an emerging theory that allocation of resources by plants to growth or defence are interrelated, not alternatives as currently assumed. Like many crops, sorghum produces toxic cyanide, especially during droughts but its wild relatives make much less. This project aims to discover why cyanide is so common in domesticated plants and why levels increase with stress. This has important implications for de ....Australia's native sorghums: a model for testing plant adaptation theories. This proposal tests an emerging theory that allocation of resources by plants to growth or defence are interrelated, not alternatives as currently assumed. Like many crops, sorghum produces toxic cyanide, especially during droughts but its wild relatives make much less. This project aims to discover why cyanide is so common in domesticated plants and why levels increase with stress. This has important implications for developing crops that are high yielding and also climate resilient. Expected outcomes include full genome sequences for all of Australia’s unique native sorghums, confirmation of new theories on the interrelationships between defence and growth and identification of new traits vital for developing the crops of the future.
