A portable RNA-editing machine. Many plants maintain an elaborate RNA-editing machine that allows them to correct accumulated errors in their organellar genomes by specifically editing the RNA transcripts of the affected genes. A portable and adaptable version of this molecular machine would have significant biotechnological value, providing the ability to correct genetic errors, and to intervene in gene regulation without permanently altering a genome. The project aims to combine molecular and ....A portable RNA-editing machine. Many plants maintain an elaborate RNA-editing machine that allows them to correct accumulated errors in their organellar genomes by specifically editing the RNA transcripts of the affected genes. A portable and adaptable version of this molecular machine would have significant biotechnological value, providing the ability to correct genetic errors, and to intervene in gene regulation without permanently altering a genome. The project aims to combine molecular and structural biology approaches to fully characterise the components of the machine, thus allowing us to reconstitute it in cell-free systems and ultimately in other organisms.Read moreRead less
Can we engineer plants to grow on salty soils? This project aims to answer questions about how plants can sustain their growth on salty soils. Plant-derived products constitute a pillar for our society. However, crop yields may be severely penalised due to unfavourable growth conditions, including soil salinity. This is particularly relevant for Australia as a large fraction of its arable land is affected by salt. This project aims to use molecular and cell biology techniques to resolve mechanis ....Can we engineer plants to grow on salty soils? This project aims to answer questions about how plants can sustain their growth on salty soils. Plant-derived products constitute a pillar for our society. However, crop yields may be severely penalised due to unfavourable growth conditions, including soil salinity. This is particularly relevant for Australia as a large fraction of its arable land is affected by salt. This project aims to use molecular and cell biology techniques to resolve mechanisms of how the synthesis of cellulose, which constitutes the bulk of a plant's biomass, is maintained in plants during salt stress. This project has potential for climate change mitigation, enhanced plant biomass production and improved fuel security.Read moreRead less
Advanced cryobanking for recalcitrant-seeded Australian rainforest plants. 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 attr ....Advanced cryobanking for recalcitrant-seeded Australian rainforest plants. 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
Advanced cryobanking for propagation-recalcitrant and critically endangered plant species. This project aims to advance methods for the conservation of recalcitrant/threatened plant species to achieve best practice ecological restoration in areas of high biodiversity. In particular, the nature of freezing and dehydration damage to cell membranes at various stages of tissue culture and cryopreservation will be investigated to try to minimise deleterious effects. In addition, metabolic changes tha ....Advanced cryobanking for propagation-recalcitrant and critically endangered plant species. This project aims to advance methods for the conservation of recalcitrant/threatened plant species to achieve best practice ecological restoration in areas of high biodiversity. In particular, the nature of freezing and dehydration damage to cell membranes at various stages of tissue culture and cryopreservation will be investigated to try to minimise deleterious effects. In addition, metabolic changes that affect cryogenic survival will be assessed to provide further insight into the role of oxidative stress and the toxicity of cryopreservation processes. Ultimately, improved cryogenic protocols will be developed to maintain the integrity of long-term cryobanks of key species for ecological restoration, such as in post-mined areas.Read moreRead less

This project contributes to the National Research Priority of an environmentally sustainable Australia. The project will underpin management strategies of vegetation in saline lakes/marshes; wetlands of national importance to biodiversity. Understanding the vegetation at the Fortescue Marshes will provide vital base-information for the future, and have flow-on benefits for improved strategies for revegetation of saline lands. Improvement of the publicly available Herbarium database on samphire species will also enable improved species identifications for conservation and/or rehabilitation efforts. The project will train a PhD student in an industry-relevant research area that is currently in high demand.Read moreRead less

Stomata functioning in halophytes for improved plant stress tolerance. This project aims to determine how halophytes balance photosynthesis and water loss under extreme soil conditions. Salinity and drought affect crop production. Plants’ ability to balance carbon dioxide uptake and water loss through stomata determines how they cope with stressors. Halophytes can achieve this balance at conditions that normally kill 99% of crops, but how they do so is unknown. This project will characterise the ....Stomata functioning in halophytes for improved plant stress tolerance. This project aims to determine how halophytes balance photosynthesis and water loss under extreme soil conditions. Salinity and drought affect crop production. Plants’ ability to balance carbon dioxide uptake and water loss through stomata determines how they cope with stressors. Halophytes can achieve this balance at conditions that normally kill 99% of crops, but how they do so is unknown. This project will characterise the transport systems mediating stomata function in halophytes and contribute to understanding the molecular and physiological basis of their operation. This should allow breeders to use this trait to improve crop performance under conditions of extreme salinity and drought.Read moreRead less
Peridinin-chlorophyll-protein complex: unravelling the unique photosynthetic apparatus of dinoflagellates in response to climatic variation. Dinoflagellates sustain the food chain. They live in coral and in ice, and also create toxic algal blooms. This project will dissect the unique photosynthetic machinery of these organisms to learn how they adapt and thrive in extreme environments. This new knowledge will predict how dinoflagellate-based ecosystems will respond to future climate change.
