Biology of flowering plant male gametic cells in relation to fertilization. The world food supply is primarily dependent on plants. The continuation of an adequate food supply depends upon the success of fertilization that involves the fusion of the sperm cell with the egg cell. The entire process of fertilization can be manipulated once the specific molecules involved in its regulation have been identified. This project deals with the discovery of male gamete biomolecules involved in fertili ....Biology of flowering plant male gametic cells in relation to fertilization.

The knowledge obtained will have potential applications in developing novel breeding technologies for improved crop plants.Read moreRead less
When to Flower - analysis of a novel genetic locus (FLH) that accelerates flowering. The development of plants is largely determined by the environment. The flowering time of some plants, including many crop species, is accelerated by vernalization, a long period of low temperature. Using a combination of genetic and molecular techniques in the model plant Arabidopsis, this project will characterise a novel locus, FLH that enhances the response to vernalization. The identification of FLH will si ....When to Flower - analysis of a novel genetic locus (FLH) that accelerates flowering. The development of plants is largely determined by the environment. The flowering time of some plants, including many crop species, is accelerated by vernalization, a long period of low temperature. Using a combination of genetic and molecular techniques in the model plant Arabidopsis, this project will characterise a novel locus, FLH that enhances the response to vernalization. The identification of FLH will significantly enhance our understanding of flowering time pathways, and may lead to the generation of plant varieties designed to flower faster or slower than usual.Read moreRead less
The molecular basis of self-incompatibility in solanaceous plants. This study will examine plant reproduction, the processes that ultimately lead to seeds being formed. Seeds are a major source of food for human societies. Benefits likely to arise from this study include an improved knowledge of plant reproduction which could lead to the production of better crops and more sustainable agricultural systems. By examining reproduction in a native plant, this study will also improve our understan ....The molecular basis of self-incompatibility in solanaceous plants. This study will examine plant reproduction, the processes that ultimately lead to seeds being formed. Seeds are a major source of food for human societies. Benefits likely to arise from this study include an improved knowledge of plant reproduction which could lead to the production of better crops and more sustainable agricultural systems. By examining reproduction in a native plant, this study will also improve our understanding of Australia's flora and could help improve management strategies for rare and endagered species. Through the training of students and researchers, this study will contribute highly skilled individuals to the Australian economy.Read moreRead less
Fossil evidence for the evolution of Australia's modern vegetation. This project will provide Australian scientists and public with a better appreciation of the origins of our modern flora by providing evidence of landscape and community change over the past 40 million years, the nature of major extinction and diversification events and the response of the vegetation to climate change. The project will raise our understanding of the changing role of fire in the Australian landscape. It will also ....Fossil evidence for the evolution of Australia's modern vegetation. This project will provide Australian scientists and public with a better appreciation of the origins of our modern flora by providing evidence of landscape and community change over the past 40 million years, the nature of major extinction and diversification events and the response of the vegetation to climate change. The project will raise our understanding of the changing role of fire in the Australian landscape. It will also revise our understanding of the geological evolution of southeastern Australian basins and provide better genetic modelling of Victoria's brown coal deposits. Importantly, the project will provide postgraduate research training opportunities for a new generation of palaeobotanists and coal petrologists.Read moreRead less
Genetic control of plant organ growth. Plants organs, such as leaves and petals, have a distinct size and shape reflecting differences in growth. Despite its importance, very little is known about the mechanisms that regulate growth. The objectives of this proposal are a) to test whether organ growth depends on cell-cell signalling and b) to identifying genes that regulate growth, and to characterize their molecular function.
