These include understanding the impact of the environment on plant and animal development, pest animal control, development of new biotechnology tools, new drugs and new methods for the detection of narcotics and explosives.Read moreRead less
The Dynamics of Plant Cell Division-Discovering the Mechanisms of Organelle Inheritance. This project seeks to understand molecular mechanisms responsible for organelle partitioning in dividing plant cells. Understanding these mechanisms will contribute new knowledge relevant to plant biotechnology (eg chloroplast transformation, cytoplasmic male sterility, plant development and totipotency) and thus to Australian agriculture broadly.

This project seeks to understand molecular mechanisms responsible for organelle partitioning in dividing plant cells. Understanding these mechanisms will contribute new knowledge relevant to plant biotechnology (eg chloroplast transformation, cytoplasmic male sterility, plant development and totipotency) and thus to Australian agriculture broadly. This project will enhance Australian research capacity in the fields of organelle inheritance and plant cytoskeletal dynamics and thus will maintain Australia's leading reputation in these fields. In addition, the project will maintain a high quality and productive research environment capable of providing excellent research training for new scientists in this field. Read moreRead less
Is transport of miRNAs essential for plant development? This project will provide knowledge of how a new class of biologically active molecule (micro RNA) regulates expression of genes at sites in the plant that are critical for growth and development. MicroRNAs are believed to influence the size and shape of plants, how rapidly they grow and how well they produce and fill seeds. These molecules are part of a group of bioactive signals that move throughout the plant, functioning like hormones bu ....Is transport of miRNAs essential for plant development? This project will provide knowledge of how a new class of biologically active molecule (micro RNA) regulates expression of genes at sites in the plant that are critical for growth and development. MicroRNAs are believed to influence the size and shape of plants, how rapidly they grow and how well they produce and fill seeds. These molecules are part of a group of bioactive signals that move throughout the plant, functioning like hormones but directly influencing how well critical genes work. Their exploitation holds great promise for manipulating plant performance and enhancing crop yields. Read moreRead less
Molecular mechanisms of spectral extension in photosynthesis: the substitution and formation of the novel pigment chlorophyll d. This project builds on new discoveries of novel chlorophylls and how their spectral properties are fine-tuned in photosynthetic bacteria. We will focus on how key photopigments, the chlorophylls, are biosynthesised, including their enzyme structures, mechanisms and regulatory elements. Understanding the power of natural selection on spectral extension in photosynthesis ....Molecular mechanisms of spectral extension in photosynthesis: the substitution and formation of the novel pigment chlorophyll d.

We will focus on how key photopigments, the chlorophylls, are biosynthesised, including their enzyme structures, mechanisms and regulatory elements. Understanding the power of natural selection on spectral extension in photosynthesis will shed light on the evolutionary development of photopigments, and will allow us explore the possibilities for the production of new pigments in solar energy research.Read moreRead less
Are plants wasting water in the dark? This project aims to measure stomatal conductance to water vapour in the dark in economically important species to understand how conductance is regulated in the dark, and its adaptive significance. Leaves of most plants continue to lose water in the dark because stomata remain open. No photosynthetic carbon fixation can occur in the dark so water-use efficiency is reduced, and this reduction influences crop yield, forest growth, catchment water yield and c ....Are plants wasting water in the dark? This project aims to measure stomatal conductance to water vapour in the dark in economically important species to understand how conductance is regulated in the dark, and its adaptive significance. Leaves of most plants continue to lose water in the dark because stomata remain open. No photosynthetic carbon fixation can occur in the dark so water-use efficiency is reduced, and this reduction influences crop yield, forest growth, catchment water yield and climate feedback. Existing mechanistic models of stomatal conductance will be extended to include responses in the dark, and aim to be used to predict the reduction in potential daytime water loss (which is coupled to carbon gain) due to nocturnal stomatal conductance for crops and forests.Read moreRead less
Novel laser isotopic techniques to assess the potential for water-use efficiency improvement of Australian crops. This project aims to develop new methods to reduce the water used by grain crops while maintaining productivity by advancing knowledge of the regulation plant carbon gain and water loss.

This project aims to develop new methods to reduce the water used by grain crops while maintaining productivity by advancing knowledge of the regulation plant carbon gain and water loss. Novel laser-lased measurement systems developed and applied in this project will provide new mechanistic understanding of plant carbon-water dynamics for individual leaves and at the whole crop scale. Water availability is the most pressing environmental issue facing the Australian grain industry, so improvements in the efficiency with which water is used will have profound economic and environmental effects.Read moreRead less

Expected outcomes of this project include the world's first 3D spatially-explicit, anatomically accurate model of leaves of crop plants to allow virtual experiments identifying optimized anatomy for improved photosynthetic performance. Benefits to the agricultural industry include increased crop productivity and water-use efficiency to meet future global food demand and to make the most of Australia's limited water resourcesRead moreRead less
Carbon flux and its regulation in metabolic networks. Allocation of photo-assimilates throughout metabolic networks are central to a plants ability to cope with changes in its environment. This project will combine the use of quantitative molecular, chemical and imaging techniques to characterise the flux of resources and its regulation through metabolic networks of Australian native and crop plants.
Genome Approaches to Investigate Metabolic Coordination in Plant Cells. Metabolism of C and N in legume nodules requires interaction between the symbiotic bacteria and plant organelles, particularly metabolism in plastids and mitochondria. Fixed N is assimilated through the de novo synthesis of purines in both plastids and mitochondria. However, each of the nine pathway enzymes is encoded by a single gene, indicating each protein is targeted to both organelles. Purine metabolism will provide ....Genome Approaches to Investigate Metabolic Coordination in Plant Cells. Metabolism of C and N in legume nodules requires interaction between the symbiotic bacteria and plant organelles, particularly metabolism in plastids and mitochondria. Fixed N is assimilated through the de novo synthesis of purines in both plastids and mitochondria. However, each of the nine pathway enzymes is encoded by a single gene, indicating each protein is targeted to both organelles. Purine metabolism will provide a model to assess the more general occurrence of dual-targeted proteins in plants. The aim is to identify and eventually exploit the signalling mechanism(s) that mediate communication between plastids and mitochondria.Read moreRead less
Transport systems that underpin nitrogen efficient maize. This project aims to define the nitrogen transport network involved in the uptake, storage and redistribution of inorganic nitrogen (nitrate and ammonium) over the developmental life cycle of maize. This information will provide novel insight into the genetic control of nitrogen use in maize and other cereal crops.
