Potential of Corymbia torelliana hybrids for hardwood forestry and investigation of their seed dispersal by Trigona bees. Cadaghi (Corymbia torelliana) and their hybrids with spotted gums (C. variegata complex) have enormous potential for plantation forestry. These hybrids have many excellent features that make them exciting as hardwood species, such as resistence to disease, tolerance of marginal environments, good wood properties, and fast growth rates. This project will create hybrids between ....Potential of Corymbia torelliana hybrids for hardwood forestry and investigation of their seed dispersal by Trigona bees. Cadaghi (Corymbia torelliana) and their hybrids with spotted gums (C. variegata complex) have enormous potential for plantation forestry. These hybrids have many excellent features that make them exciting as hardwood species, such as resistence to disease, tolerance of marginal environments, good wood properties, and fast growth rates. This project will create hybrids between Corymbia torelliana and spotted gums to identify hybrids which are suitable for sustainable wood production on marginal agricultural lands.
An unusual feature of Cadaghi is that native Trigona bees disperse their seeds. This project will investigate this unique seed dispersal mechanism and identify features of hybrids that are not attractive to bees. This will prevent environmental problems by preventing hybrids from dispersing seeds, becoming weedy and harming the Trigona bees.

Feasting on protein? Strategies of organic nitrogen acquisition by plant roots. Crops require large amounts of nitrogen for growth. Application of nitrogen fertiliser enhances yield, but causes off-site nitrogen pollution, a main threat to ecosystem integrity. Most nitrogen in soil occurs as organic complexes that are broken down by soil organism into small compounds, which are taken up roots or lost from the soil. This project will generate fundamental knowledge of how an Australian species and ....Feasting on protein? Strategies of organic nitrogen acquisition by plant roots. Crops require large amounts of nitrogen for growth. Application of nitrogen fertiliser enhances yield, but causes off-site nitrogen pollution, a main threat to ecosystem integrity. Most nitrogen in soil occurs as organic complexes that are broken down by soil organism into small compounds, which are taken up roots or lost from the soil. This project will generate fundamental knowledge of how an Australian species and a crop species with unusual root specialisations access soil organic nitrogen, thus increasing the efficiency of nitrogen use and reducing nitrogen loss. The research employs cutting-edge techniques for sustainable resource use, improved efficiency of crops and farming systems, and preservation of Australia's biodiversity.Read moreRead less
Strigolactone, a new plant hormone: its regulation, role and potential for plant improvement. This Project will investigate a new plant hormone, one of only 10 or so discovered to date in plants. This hormone regulates shoot number, water and nutrient uptake and the ability of shoots to generate roots and develop wood. The Project will produce genetic tools and describe new processes for applications in sustainable plant improvement.
The new plant hormone controlling shoot branching. This project will create genetic tools and knowledge on the control of a new plant growth hormone that affects a diverse number of plant properties. These important traits include shoot number, water and nutrient uptake, wood production, the ability to generate roots and the ability to stimulate particular potentially devastating parasitic weeds.
New plant development discoveries stem from strigolactone research. This project involves a new plant hormone, strigolactone, and the way it controls wood and root formation in above-ground parts of plants. It will identify new plant genes involved in these processes and provide greater understanding of how plant hormones interact to control these important traits.
