Modelling spatial and temporal dynamics of rhizosphere exudation. Existing crop root systems are poorly suited to Australian soils with low nutrient availability. Using a simulation model to develop computer-aided design of 3-D root structure and function, tailored to particular environments, this project will enhance breeding for increased nutrient-use efficiency.
A novel DNA motif involved in plant mitochondrial stress responses. The future of Australia's agriculture is threatened by limited water resources, temperature extremes and soil salinity. This project aims to unravel how plants are able to adapt to this continuously changing environment, by focusing on the role of mitochondria - cellular compartments essential for energy metabolism and plant stress responses.
Role of intracellular calcium homeostasis and aluminium transport across the plasma membrane in aluminium toxicity to plants. Aluminium is the most important yield-limiting factor in acid soils throughout the world. The problem of aluminium toxicity is aggravated by continuous acidification of arable land. Mechanisms of aluminium toxicity in plant cells are poorly understood. The present project seeks to elucidate the molecular basis of the interaction between intracellular calcium homeostasis, ....Role of intracellular calcium homeostasis and aluminium transport across the plasma membrane in aluminium toxicity to plants. Aluminium is the most important yield-limiting factor in acid soils throughout the world. The problem of aluminium toxicity is aggravated by continuous acidification of arable land. Mechanisms of aluminium toxicity in plant cells are poorly understood. The present project seeks to elucidate the molecular basis of the interaction between intracellular calcium homeostasis, cytosolic pH and aluminium uptake across the plasma membrane in aluminium toxicity to plants. Knowledge of primary triggers of aluminium toxicity will pay off in a breeding programme aimed at selecting crop genotypes with increased resistance to aluminium toxicity.Read moreRead less
Stimulation of the mammalian reproductive system by olfactory pathways. This project answers fundamental questions about mammalian reproductive biology but, because we work with the sheep model, our findings can be applied to two of Australia's biggest export industries, wool and sheepmeat. Understanding the reproductive responses of our production animals to exteroceptive factors such as socio-sexual signals, photoperiod and nutrition is an important first step towards refining the management ....Stimulation of the mammalian reproductive system by olfactory pathways. This project answers fundamental questions about mammalian reproductive biology but, because we work with the sheep model, our findings can be applied to two of Australia's biggest export industries, wool and sheepmeat. Understanding the reproductive responses of our production animals to exteroceptive factors such as socio-sexual signals, photoperiod and nutrition is an important first step towards refining the management of breeding programs. It has been argued that this approach will also minimise, and perhaps even remove the need for, exogenous hormones and drugs for controlling the reproductive process.Read moreRead less
Aluminium uptake across the root-cell plasma membrane. Aluminium toxicity limits crop growth in acid soils that occupy about 24 million hectares of agricultural land in Australia. Liming can increase pH of the surface soil, but is frequently too expensive in the low-input Australian agriculture. Surface-applied lime is poorly effective in ameliorating subsoil acidity, and incorporating lime deep into the profile is prohibitively expensive and technically difficult. Hence, Al-resistant crop culti ....Aluminium uptake across the root-cell plasma membrane. Aluminium toxicity limits crop growth in acid soils that occupy about 24 million hectares of agricultural land in Australia. Liming can increase pH of the surface soil, but is frequently too expensive in the low-input Australian agriculture. Surface-applied lime is poorly effective in ameliorating subsoil acidity, and incorporating lime deep into the profile is prohibitively expensive and technically difficult. Hence, Al-resistant crop cultivars are important part of sustainable farming in Australia. This project will characterise early triggers of Al toxicity in plants, providing a foundation for increasing Al resistance in crop cultivars. Understanding the physiological basis of Al toxicity will lead to improved crop breeding strategies.Read moreRead less

Functional analysis of novel mitochondrial outer membrane proteins in Arabidopsis. Mitochondria play central roles in the life and death of cells. This project will characterise the functions of proteins on the mitochondrial surface, which mediate signals that define mitochondrial function, providing novel approaches to modify mitochondrial function and plant growth.
Optimising crop root systems to enhance capture of soil water and nutrients. The project’s goal is to improve crop breeding for increased efficiency of acquiring soil resources. Increasing a crop’s efficiency in capturing soil resources (water and nutrients) is an imperative task in ensuring food security. This project plans to use barley as the model cereal crop and characterise root traits in a panel of cultivars assembled to represent maximum diversity as well as in biparental mapping populat ....Optimising crop root systems to enhance capture of soil water and nutrients. The project’s goal is to improve crop breeding for increased efficiency of acquiring soil resources. Increasing a crop’s efficiency in capturing soil resources (water and nutrients) is an imperative task in ensuring food security. This project plans to use barley as the model cereal crop and characterise root traits in a panel of cultivars assembled to represent maximum diversity as well as in biparental mapping population followed by association and linkage mapping to identify genetic markers linked with specific root traits. These markers will be incorporated into a computer model of 3-D root structure and function. The enhanced computer model would be able to simulate optimal root systems for specific environments and generate a list of selectable root-trait markers.Read moreRead less
Containment and reduction of rework in offshore oil and gas projects. This research will ensure that hydrocarbon projects are delivered successfully, on time and budget, safely to specified quality and with minimal environment impact. The successful delivery of such projects is thwarted by rework made during the design process. Strategies to reduce rework from occurring in the future will be developed.
