Mid-rotation diagnosis and management options for correction of water and nutrient deficiencies in plantation-grown eucalypts. This research will improve productivity of bluegum plantations by improving current diagnostic techniques (foliage and soil analysis) for nutrient disorders and the supply of water. Using a novel phloem sampling and analysis technique, we will develop a nutrient (e.g. N, P) and water diagnosis procedure that is quick, cheap, robust and reliable for field use. A major in ....Mid-rotation diagnosis and management options for correction of water and nutrient deficiencies in plantation-grown eucalypts. This research will improve productivity of bluegum plantations by improving current diagnostic techniques (foliage and soil analysis) for nutrient disorders and the supply of water. Using a novel phloem sampling and analysis technique, we will develop a nutrient (e.g. N, P) and water diagnosis procedure that is quick, cheap, robust and reliable for field use. A major innovation will be distinguishing the effects of shortages of water on growth from those of other growth influences. Overall, this project will provide a highly significant theoretical, conceptual and practical advance in mid-rotation, diagnostics for plantations with considerable commercial promise.Read moreRead less
Functional diversity in root systems that are critical for water and nutrient acquisition by Australian monocotyledons. Specialised root structures facilitate water and nutrient acquisition in grass-like sedges, a major vegetation type on nutrient-poor, intensely weathered soils in Australia. The project will enhance our understanding of key root structures and functional traits for water and nutrient acquisition in various habitats. The identification of such structures and traits will contribu ....Functional diversity in root systems that are critical for water and nutrient acquisition by Australian monocotyledons. Specialised root structures facilitate water and nutrient acquisition in grass-like sedges, a major vegetation type on nutrient-poor, intensely weathered soils in Australia. The project will enhance our understanding of key root structures and functional traits for water and nutrient acquisition in various habitats. The identification of such structures and traits will contribute to Australia's excellent international reputation in this discipline. Increased fundamental insight into the strategies of perennial monocotyledons in Australian ecosystems will be directly relevant to difficult cases of landscape restoration on skeletal soils with widely varying water availability and thus addresses the National Research Priority: An Environmentally Sustainable Australia.Read moreRead less
Does calcium toxicity explain the absence of most Proteaceae from calcareous habitats? Native Proteaceae plants inhabit sandy environments across Australia, but are invariably limited in their distribution by soil conditions. This project will determine elemental and genetic factors that determine Proteaceae distribution and survival, in order to improve ecosystem conservation and restoration strategies and preserve biodiversity.
The role of mycorrhizal fungi in nutrient supply and habitat specificity of the rare underground orchid (Rhizanthella gardneri). The underground orchid (Rhizanthella gardneri) is an extremely rare achlorophyllous myco-heterotroph that shares a mycorrhizal fungus with broom bush (Melaleuca uncinata). This project will investigate habitat requirements for R. gardneri and assess the orchid dependence on M. uncinata for carbon and nutrient supply. We will measure magnitude and timing of nutrient a ....The role of mycorrhizal fungi in nutrient supply and habitat specificity of the rare underground orchid (Rhizanthella gardneri). The underground orchid (Rhizanthella gardneri) is an extremely rare achlorophyllous myco-heterotroph that shares a mycorrhizal fungus with broom bush (Melaleuca uncinata). This project will investigate habitat requirements for R. gardneri and assess the orchid dependence on M. uncinata for carbon and nutrient supply. We will measure magnitude and timing of nutrient and carbon transfers between M. uncinata roots, fungal hyphae and R. gardneri using stable isotope techniques. This project will provide knowledge essential for conserving the underground orchid, a unique Australian plant, and other critically endangered orchids.Read moreRead less

Summary
Plant Phenomics Imaging and Analysis Facility. The Australian plant science community faces a major challenge in being able to comprehensively characterise the performance or phenotype of plants in a high throughput manner necessary for post-genomic era science with model plant species, smart-breeding of crop plants and to assess plant-environment interactions. Our capacity to accurately 'phenotype' either a new mutant or a new variety has fallen behind out capacity to generate novel genetic mat ....Plant Phenomics Imaging and Analysis Facility. The Australian plant science community faces a major challenge in being able to comprehensively characterise the performance or phenotype of plants in a high throughput manner necessary for post-genomic era science with model plant species, smart-breeding of crop plants and to assess plant-environment interactions. Our capacity to accurately 'phenotype' either a new mutant or a new variety has fallen behind out capacity to generate novel genetic material. This facility will significantly boost research outputs across a range of disciplines pivotal to Australia's future agricultural plant productivity and environmental sustainability.

Understanding responses of tightly coupled ecological interactions of biota vulnerable to climate change: endangered Australian cycads and their pollinators. Australian cycads are iconic plants. Most of the forty Macrozamia species have small, fragmented distributions and fifteen are endangered or vulnerable. They are at risk from harvesting by collectors and pollination failure, because a highly specialised relationship with insect pollinators is crucial to their persistence in nature. Cycads r ....Understanding responses of tightly coupled ecological interactions of biota vulnerable to climate change: endangered Australian cycads and their pollinators. Australian cycads are iconic plants. Most of the forty Macrozamia species have small, fragmented distributions and fifteen are endangered or vulnerable. They are at risk from harvesting by collectors and pollination failure, because a highly specialised relationship with insect pollinators is crucial to their persistence in nature. Cycads release chemo-attractants by increasing cone temperatures when ambient temperature reaches a threshold, so climate change will affect these systems. An understanding of this temperature-dependent relationship will help predict future fates of cycads and other tightly coupled ecological interactions. Our integrated approach will generate knowledge to help manage vulnerable Australian biodiversity.Read moreRead less
PHYSIOLOGICAL AND BIOCHEMICAL DISSECTION OF COBALT ACCUMULATION BY PLANTS. Co is a valuable metal for the Australian economy. The project will advance phytomining of non-economic Co ores and also the phytoremediation of (60)Co-contaminated soils. It will assist development of phytotechnologies for Co, eg improvement of Co content of fodder crops for ruminants in Co-deficient areas. All these applications will benefit ARC's National Research Priorities Goal 1: an environmentally friendly Australi ....PHYSIOLOGICAL AND BIOCHEMICAL DISSECTION OF COBALT ACCUMULATION BY PLANTS. Co is a valuable metal for the Australian economy. The project will advance phytomining of non-economic Co ores and also the phytoremediation of (60)Co-contaminated soils. It will assist development of phytotechnologies for Co, eg improvement of Co content of fodder crops for ruminants in Co-deficient areas. All these applications will benefit ARC's National Research Priorities Goal 1: an environmentally friendly Australia. Understanding Co uptake by accumulator species will also promote awareness, conservation and sustainable use of biodiversity in Australia. Outcomes will impact on Goal 3: frontier technologies, as the potential spin-off applications of Co-based phytotechnologies will fuel future environmental technologies in Australia.Read moreRead less
