Summary
Pushing the limits of fluorescence microscopy with adaptive optics. This project aims to establish an adaptive optics, super-resolution optical microscopy facility to image cellular events with the highest possible spatial resolution, in a whole cell or tissue context. Sophisticated computer-controlled deformable mirrors will be used to correct the way light is distorted as it passes through specimens, thereby overcoming aberrations found in thick and complex samples.

This project aims to establish an adaptive optics, super-resolution optical microscopy facility to image cellular events with the highest possible spatial resolution, in a whole cell or tissue context. Sophisticated computer-controlled deformable mirrors will be used to correct the way light is distorted as it passes through specimens, thereby overcoming aberrations found in thick and complex samples. This adaptive optics system will enable researchers to study complex behaviour of biological specimens, at the optical resolution limit in plant and animal tissues, leading to basic biology and biotechnology outcomes in biofuels, biomaterials and biomedicines.Read moreRead less

This project seeks molecular understanding of regulatory mechanisms responsible for inducing formation of specialized plant cells that are of central importance in controlling nutrient transport. These so-called "transfer cells" play pivotal roles in determining crop nutrition and hence yield under normal and stressful environments such as soil nutrient deficiencies and salinity. Discovering regulatory mechanisms that control formation of these specialized cells will maintain Australia's international reputation in this field of research. In addition, the information platform generated may provide technological opportunities to optimise nutrient flows in healthy plants, combat certain environmental stresses and control pathogen attack.

Some photosynthetic organisms have a remarkable ability to accumulate long-wavelength absorbing photopigments, such as chlorophyll f, in response to the changed light and nutrient environments. The project aims to demonstrate that the structure and function of undefined chlorophyll f-binding proteins can be changed and controlled in desired light and nutrient conditions. The optimised photosynthesis strengthens their adaptation capability and challenges the long wavelength limits of photosynthesis. The research outcome will provide tools and a molecular blueprint for the adaptation of photosynthesis with optimised energy transfer pathway and efficiency for potential future molecular applications.

Wall ingrowth formation in plant transfer cells - discovering regulatory transcription factor cascades. This project will discover how specialised plant 'transfer cells', designed for optimum transport of nutrients, develop complex wall ingrowths. Discovering the genes which regulate wall ingrowth deposition in these cells will generate opportunities to improve crop yield and therefore contribute to addressing global food security.
Targeting chloroplasts to enhance crop salt tolerance. Yield losses in crop plants due to increasingly saline soils are linked to the effects of salt on chloroplasts. By comparing chloroplast water- and salt-transport mechanisms of closely related salt-loving and salt-sensitive plants, this Fellowships aims to discover how chloroplasts maintain function in saline conditions. Novel biophysics and molecular techniques will be used to characterise transporters in model plants, and proof-of-concept ....Targeting chloroplasts to enhance crop salt tolerance. Yield losses in crop plants due to increasingly saline soils are linked to the effects of salt on chloroplasts. By comparing chloroplast water- and salt-transport mechanisms of closely related salt-loving and salt-sensitive plants, this Fellowships aims to discover how chloroplasts maintain function in saline conditions. Novel biophysics and molecular techniques will be used to characterise transporters in model plants, and proof-of-concept complementation experiments aim to confer salt tolerance on sensitive plants. These fundamental insights are likely to lead to rapid, step-change improvements in salt tolerance, especially in agriculturally relevant crops, to benefit Australia’s agri-industry and ensure food security in the future.Read moreRead less

This project aims to develop an interdisciplinary research alliance to enhance the efficiency of ecological restoration for recalcitrant Australian rainforest plant species. The project expects to provide fundamental knowledge to target two major impediments to cryostorage of recalcitrant-seeded native species: desiccation sensitivity with relatively large size, and active metabolism and precocious germination. These attributes severely limit the time available for effective use of collected germplasm for long-term storage. A combination of biochemical, biophysical and molecular simulation approaches will be used to optimise cryopreservation of a wide range of endangered Australian rainforest species. This should provide significant benefits such as enabling conservation agencies to greatly enhance their ability to preserve the unique Australian rainforest flora, particularly given current threats due to habitat loss and global warming.Read moreRead less

Water availability is a primary determinant of plant growth and the distribution of plant species and communities throughout the world. In Australia, climate change is predicted to result in increasing temperatures and shifting precipitation patterns, leading to more intense droughts in some areas. This project will examine the resilience of Australian forests and woodlands to drought under both current and future climate scenarios. The results of this work will feed into the new generation of dynamic global vegetation models, allowing for robust prediction of changes in the structure and productivity of Australian vegetation communities in the face of rapid climate change.Read moreRead less
