A Core Western Australian Cell Sorting Facility - Ultra-Small Objects and Rare Cell Populations. This new generic capacity to rapidly isolate structures smaller than the cell has extraordinarily wide application in the biological sciences.

This new generic capacity to rapidly isolate structures smaller than the cell has extraordinarily wide application in the biological sciences. Making this capacity widely accessible through a core facility to the Western Australian research community will generate research outcomes of national and community benefit. Sorting chromosomes to better understand genetic abnormalities and sorting bacteria to better understand and reduce bacterial infection will result in improvements in human health. Sorting parasites, bacteria and immune cells will lead to new animal vaccines for parasites and diseases such as bird flu. Sorting marine plankton will lead to more sustainable marine ecosystems and fisheries.Read moreRead less
Membrane transporters in oxidative stress signalling and tolerance in plants. Oxidative stress imposed by salinity and drought severely limits agricultural crop production, resulting in multibillion dollar losses to farmers. Australia is one of the driest continents, with a significant proportion of arable land affected by salinity. Thus, developing salt- and drought tolerant species is critical to minimise the impact of these stresses on crop production. This project will reveal specific ionic ....Membrane transporters in oxidative stress signalling and tolerance in plants. Oxidative stress imposed by salinity and drought severely limits agricultural crop production, resulting in multibillion dollar losses to farmers. Australia is one of the driest continents, with a significant proportion of arable land affected by salinity. Thus, developing salt- and drought tolerant species is critical to minimise the impact of these stresses on crop production. This project will reveal specific ionic mechanisms mediating reactive oxygen species signalling and tolerance in plants. This will help achieve the above goal by providing plant breeders with vital information on key genes controlling oxidative stress tolerance in plants. Read moreRead less
Coping with flooding: nutrient transport in oxygen-deprived roots. Flooding damages plants by reducing oxygen supply to roots. The project will study effects of low oxygen on nutrient transport by roots. Understanding root functioning during low oxygen will enhance knowledge of plant acclimation to soil water logging. The project will contribute to the National Goal of 'Responding to Climate Change and Variability'.
Diversity of pollination biology in heat-producing flowers. This research is an entirely new approach to understanding pollination biology. It will highlight the value of ecological diversity in tropical ecosystems and will work toward conservation of these threatened habitats. The project is very strong in developing international links, involving Australia, Germany, France, Turkey, Brazil, Guyana, India and Malaysia. By supporting research involving the International Canopy Crane Network, A ....Diversity of pollination biology in heat-producing flowers. This research is an entirely new approach to understanding pollination biology. It will highlight the value of ecological diversity in tropical ecosystems and will work toward conservation of these threatened habitats. The project is very strong in developing international links, involving Australia, Germany, France, Turkey, Brazil, Guyana, India and Malaysia. By supporting research involving the International Canopy Crane Network, Australia will be recognised as a major contributor to the multinational effort. The project deals with energetics of scarab beetles, with work on reproductive energetics of natural and pest species. Research maintains and develops critical thought, essential for effective university teaching and training.Read moreRead less

Summary
Evolutionary Adaptation of the Chemical Language of Nutrient Acquisition Strategies in Higher Plants. The autotrophic and sessile nature of plants means that they need to respond to nutrient limitations in a finely tuned manner to grow and survive. Metabolites play an important role during these adaptations, either as direct modulators or as biochemical indicators of the pathways activated. Plants have evolved from relatively simple unicellular organisms that have a remarkable adaptability to re ....Evolutionary Adaptation of the Chemical Language of Nutrient Acquisition Strategies in Higher Plants. The autotrophic and sessile nature of plants means that they need to respond to nutrient limitations in a finely tuned manner to grow and survive. Metabolites play an important role during these adaptations, either as direct modulators or as biochemical indicators of the pathways activated. Plants have evolved from relatively simple unicellular organisms that have a remarkable adaptability to respond to their environment through metabolite-modulated quorum-sensing mechanisms. Preliminary evidence suggests that plants have either retained some of this ability or have evolved novel nutrient recognition strategies. This project will elucidate these pathways to gain new insights into nutrient acquisition in plants.Read moreRead less
More than defence: primary roles for cyanogenic glucosides. The tropical crop, sorghum, produces toxic cyanide to avoid being eaten by herbivores, but this diverts resources away from growth and reproduction. Using non-toxic sorghum mutants, this project seeks to explain how cyanide production is regulated and enhance agricultural efficiency in the face of climate change.

Summary
410 million years of stomatal evolution: key innovations in the transition from passive valves to active pores. Central to the supremacy of seed plants was the evolution of active, metabolic control of the stomata; the pores that regulate both plant productivity and water loss. However, little is known about the transition from passive control of stomata in seedless plants to active stomatal control in seed plants. This project will identify the key physiological and genetic innovations that und ....410 million years of stomatal evolution: key innovations in the transition from passive valves to active pores. Central to the supremacy of seed plants was the evolution of active, metabolic control of the stomata; the pores that regulate both plant productivity and water loss. However, little is known about the transition from passive control of stomata in seedless plants to active stomatal control in seed plants. This project will identify the key physiological and genetic innovations that underpinned the evolution of stomatal control over the past 410 million years. Understanding these evolutionary innovations will offer important insights into stomatal function in seed plants, as well as informing models of global productivity and water use through time, with benefits for Australian agriculture and natural resource management.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
Understanding the mechanisms of thermal acclimation in the symbiotic algae (Symbiodinium) within cnidarian corals. Global warming is a major threat to coral reefs, contributing to devastating coral bleaching. This project will provide new insight into how coral reefs can respond to rising global temperature through clarifying the thermal acclimation mechanisms in corals using molecular techniques.
