The metabolic and enzymatic regulation of C4 photosynthesis and its impact on photosynthetic productivity. Australia's tropical pastures are dominated by plants utilising the C4 photosynthetic pathway. World wide C4 grasslands contribute to approximately 20% of global primary productivity. C4 plants also include important crop species such as maize, sorghum and sugar cane and are considered ideal species for bio-fuel production. This project will use a novel functional genomic/metabolomics appro ....The metabolic and enzymatic regulation of C4 photosynthesis and its impact on photosynthetic productivity. Australia's tropical pastures are dominated by plants utilising the C4 photosynthetic pathway. World wide C4 grasslands contribute to approximately 20% of global primary productivity. C4 plants also include important crop species such as maize, sorghum and sugar cane and are considered ideal species for bio-fuel production. This project will use a novel functional genomic/metabolomics approach to provide fundamental insights into the biochemical regulation of C4 photosynthesis under different environmental conditions. This will aid in the development of mathematical models of C4 photosynthesis required in climate models of CO2 exchange and enhance our ability to improve photosynthetic performance of agricultural species.Read moreRead less
Plant Genes Conferring Resistance to Ultraviolet Radiation. Ultraviolet (UV) radiation induces DNA damage that can decrease plant growth and productivity. Our aim is to begin deciphering the mechanisms responsible for the UV resistance phenotype in plants by: 1) isolating genes that control processing of UV-induced DNA damage; 2) determining the influence of UV on gene activity; and 3) elucidating the functions and essential interactions of the gene products. The results of this study will help ....Plant Genes Conferring Resistance to Ultraviolet Radiation. Ultraviolet (UV) radiation induces DNA damage that can decrease plant growth and productivity. Our aim is to begin deciphering the mechanisms responsible for the UV resistance phenotype in plants by: 1) isolating genes that control processing of UV-induced DNA damage; 2) determining the influence of UV on gene activity; and 3) elucidating the functions and essential interactions of the gene products. The results of this study will help us understand how these genes operate to produce the UV resistance phenotype. This new knowledge will facilitate eventual engineering of plants to increase agricultural productivity by enhancing resistance to solar UV radiation.Read moreRead less

This project is part of the National Priorities "Frontier Technologies for Building and Transforming Australian Industries." Using innovative plant metabolic engineering technologies combined with sophisticated computer modeling we are generating green plants that produce renewable, biodegradable, bioplastics possessing properties such that they are suitable replacements for petroleum-derived products in many applications. During the course of these studies, we are increasing our basic level of understanding of plant metabolism of important bioenergy crops. The production of renewable, bioplastics in sugarcane will help to diversify the Australian sugarcane industry by providing a value-added product with significant world-wide markets.Read moreRead less
