The pathogenic fungus Fusarium oxysporum causes wilt disease in many plant species, including many that are important for Australian agriculture. Developing environmentally friendly disease protection strategies against this pathogen requires a clear understanding of infection strategies used by the fungus to invade its host. This project, along with a parallel project in host resistance mechanisms, will provide the basis for development of a world leading platform in mechanisms of fungal pathogenicity and virulence and plant disease resistance/susceptibility. Application of the knowledge gained in this project to other host-pathogen interactions will thereby provide opportunities for improved crop protection and biosecurity.Read moreRead less
Plant heterotrimeric G proteins: new roles in defence, stomatal control and ABA perception. Agriculture is an important economic activity in Australia that results in considerable export revenues.

Water is an extr ....Plant heterotrimeric G proteins: new roles in defence, stomatal control and ABA perception. Agriculture is an important economic activity in Australia that results in considerable export revenues. Two of the major problems facing agriculture around the globe are the incidence of diseases and the scarcity of water. Agricultural losses caused by plant pathogens and low water availability account for billions of dollars every year and have profound economic and social implications. Water is an extremely scarce resource in Australia and periodic droughts inflict immense losses to the Australian agricultural sector. Our research will explore new and cleaner strategies to provide crop protection as well as to increase water use efficiency.Read moreRead less

The primary aim of the project is to test hypotheses about the cognitive architecture of word production and negative priming using high-field functional magnetic resonance imaging (fMRI). Additional aims/outcomes are to apply a novel fMRI acquisition sequence that permits overt verbal responding with rapid presentation of trials and collection of the time course of the blood oxygen level dependent (BOLD) signal, and to further develop a methodology that delineates the logic of making inferences about cognitive systems from functional neuroimaging data. These represent potentially significant developments in the fields of cognitive neuroscience and functional neuroimaging.Read moreRead less

The brain is a remarkable machine that coordinates all aspects of our daily lives including the storage and retrieval of memories. Given that many age-related degenerative disorders are associated with marked changes in learning and memory it also has implications for Australia's National Research Priority 2 "Ageing well and ageing productively". This research aims to discover the basic mechanisms that underlie memory storage and how these are modulated in an emotional context. It will also shed light on states such as anxiety, depression and post-traumatic stress, enhancing our ability to identify new therapeutic targets for such disorders.Read moreRead less
Biased information processing in anxiety: Low anxiety scores, but still at risk. Information processing in anxious persons is biased if confronted with threatening stimulus materials such as words or pictures. This finding has considerable implications for our understanding of fear acquisition and maintenance and for the design of therapeutic interventions. More recent research has shown, however, that low anxious persons who employ repressive coping styles show similar biases. The present proj ....Biased information processing in anxiety: Low anxiety scores, but still at risk. Information processing in anxious persons is biased if confronted with threatening stimulus materials such as words or pictures. This finding has considerable implications for our understanding of fear acquisition and maintenance and for the design of therapeutic interventions. More recent research has shown, however, that low anxious persons who employ repressive coping styles show similar biases. The present project will follow up on these findings by combining the expertises of the two CIs in contemporary cognitive and psychophysiological research. It will not only provide new insights, but also offer research opportunities for postgraduate students, and prospects for future collaborative funding.Read moreRead less
Human learning of likes and dislikes: A test of the dual process account and an investigation of its neural substrates. Dual process accounts of human affective learning hold that affective learning, the learning of likes and dislikes, and relational learning, the learning of predictive relationships, reflect separate learning mechanisms. Affective learning, for instance, is said not to extinguish, a claim that has far reaching consequences for the design of behaviourally based treatments of a ....Human learning of likes and dislikes: A test of the dual process account and an investigation of its neural substrates. Dual process accounts of human affective learning hold that affective learning, the learning of likes and dislikes, and relational learning, the learning of predictive relationships, reflect separate learning mechanisms. Affective learning, for instance, is said not to extinguish, a claim that has far reaching consequences for the design of behaviourally based treatments of anxiety. The project will test this and other predictions of dual process accounts. Moreover, it will extent the experimental analysis of affective learning to the acquisition of likes and identify the cortical bases for aversive, appetitive, and relational learning using event related functional magnetic resonance imaging.Read moreRead less
