Small but bold: harnessing microbes to boost drought tolerance in grasses . Drought threats grasslands worldwide, and new adaptation and resilience building approaches are required to protect the wealth of ecosystem services provided by grasslands. Soil microbes offer an untapped opportunity to enhance drought survival in grasses. Yet, to harness this potential, we first need to identify the key microbial functions that contribute to plant tolerance to drought.

Drought threats grasslands worldwide, and new adaptation and resilience building approaches are required to protect the wealth of ecosystem services provided by grasslands. Soil microbes offer an untapped opportunity to enhance drought survival in grasses. Yet, to harness this potential, we first need to identify the key microbial functions that contribute to plant tolerance to drought. This project aims to determine the microbe-mediated ecological and functional mechanisms that underpin grass performance under drought. This knowledge will lay the foundation to accelerate the design and implementation of effective microbial manipulations and management strategies, and thus increase our success in protecting this important ecosystem.Read moreRead less

Agro-ecosystem sensor capability for elevated CO2 free air research facility. Agro-ecosystem sensor capability for elevated carbon dioxide-free air research facility: This project will provide infrastructure upgrades to the Australian Grains Free Air Carbon dioxide Enrichment (AGFACE) facility, globally the only FACE facility in low rainfall, non-irrigated agri-ecosystems.

Agro-ecosystem sensor capability for elevated carbon dioxide-free air research facility: This project will provide infrastructure upgrades to the Australian Grains Free Air Carbon dioxide Enrichment (AGFACE) facility, globally the only FACE facility in low rainfall, non-irrigated agri-ecosystems. Low rainfall, non-irrigated agriculture systems play a very significant role in global crop production and are predicted to be negatively affected by climate changes. The requested infrastructure will enable direct, plot scale measurements of crop water balance and water status, including crucial influence factors such as root growth and architecture and crop canopy temperatures, and allow manipulation experiments to develop adaptation options to improve crop resource use efficiencies.

Deciphering the Thermal Acclimation of Mitochondrial Respiration. Plants acclimate to the extremes of temperature following a pre-exposure to a sub-lethal increase/decrease in temperature. Recent research has revealed that proteins of oxidative phosphorylation and the tricarboxylic acid (TCA) cycle are dynamic and change their abundance in response to temperature change. Harnessing a cutting edge protein mass spectrometry approach, this project seeks to better understand how mitochondrial respir ....Deciphering the Thermal Acclimation of Mitochondrial Respiration. Plants acclimate to the extremes of temperature following a pre-exposure to a sub-lethal increase/decrease in temperature. Recent research has revealed that proteins of oxidative phosphorylation and the tricarboxylic acid (TCA) cycle are dynamic and change their abundance in response to temperature change. Harnessing a cutting edge protein mass spectrometry approach, this project seeks to better understand how mitochondrial respiration and hence adenosine triphosphate (ATP) production is maintained during temperature change. Uniquely this project will examine this in both the model plant Arabidopsis and wheat and combine both tissue, environment-induced and genotype variation to reveal a new understanding of the thermal acclimation of this major mitochondrial process.Read moreRead less
Keystone microbes and planktonic guilds in Australia's oceans. This project aims to unveil the ocean’s hidden sentinels, “keystone microbes” that underpin precious ecosystem services, and which can be used to monitor and model changes in ocean function. Marine microbes account for 90 per cent of oceanic biomass and every litre of seawater contains ~20,000 different species, but it is not known which species control ocean health and productivity. This project intends to provide definitive evidenc ....Keystone microbes and planktonic guilds in Australia's oceans. This project aims to unveil the ocean’s hidden sentinels, “keystone microbes” that underpin precious ecosystem services, and which can be used to monitor and model changes in ocean function. Marine microbes account for 90 per cent of oceanic biomass and every litre of seawater contains ~20,000 different species, but it is not known which species control ocean health and productivity. This project intends to provide definitive evidence of these keystones’ cellular level biogeochemical and metabolic capacity. Ultimately, this knowledge is expected to predict the resilience of ocean ecosystems and their response to change. The capacity to predict their dynamics will help provide investment clarity and increase healthy outcomes from activities involving human-ocean interactions such as recreation, food production and tourism.Read moreRead less

Summary
The quick and the dead: identifying mechanisms for plant drought survival. This project aims to identify genes that control plant responses to low air humidity, which enhance drought survival by restricting water loss. Most plant water loss occurs through pores called stomata. This project expects to identify the genes that close stomata within minutes of decreased humidity by determining the molecular changes that occur over this timeframe and testing candidate genes for a critical role. Divers ....The quick and the dead: identifying mechanisms for plant drought survival. This project aims to identify genes that control plant responses to low air humidity, which enhance drought survival by restricting water loss. Most plant water loss occurs through pores called stomata. This project expects to identify the genes that close stomata within minutes of decreased humidity by determining the molecular changes that occur over this timeframe and testing candidate genes for a critical role. Diverse land plant models will be examined to ensure broad applicability of results. A major expected outcome is new knowledge of genes that minimise plant water loss, which would ultimately benefit plant-based industries through new targets for breeding improved, drought-adapted varieties for food security in a drying climate.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
