How plants open up: revealing the evolution of stomatal opening mechanisms. This project aims to identify novel and conserved mechanisms that drive the opening of stomata – plant pores that enable CO2 acquisition for photosynthesis. Stomatal movements strongly affect plant productivity and water use efficiency and have profoundly influenced the earth’s climate and terrestrial ecology. This project will address critical gaps in our understanding of how plants open stomata in response to their env ....How plants open up: revealing the evolution of stomatal opening mechanisms. This project aims to identify novel and conserved mechanisms that drive the opening of stomata – plant pores that enable CO2 acquisition for photosynthesis. Stomatal movements strongly affect plant productivity and water use efficiency and have profoundly influenced the earth’s climate and terrestrial ecology. This project will address critical gaps in our understanding of how plants open stomata in response to their environment and the evolutionary history of the genes controlling this fundamental process. A major expected outcome is knowledge of the diversity of stomatal opening pathways, which should ultimately lead to improved predictions of plant responses to environmental change and assist future targeted modification of plant growth.Read moreRead less
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
ARC Australia-New Zealand Research Network for Vegetation Function. Plant species vary widely in quantitative functional traits, and in their relations to climate, soils and geography. Global generalizations are emerging. Vegetation Function network will reach from plant function into genomics and crop breeding, into palaeoecology and vegetation history, into landscape management for carbon, water and salinity outcomes, into forecasting future ecosystems under global change, and into phylogeny, ....ARC Australia-New Zealand Research Network for Vegetation Function. Plant species vary widely in quantitative functional traits, and in their relations to climate, soils and geography. Global generalizations are emerging. Vegetation Function network will reach from plant function into genomics and crop breeding, into palaeoecology and vegetation history, into landscape management for carbon, water and salinity outcomes, into forecasting future ecosystems under global change, and into phylogeny, ecoinformatics and evolutionary theory. Across this span, working groups will target nine identified opportunities for breakthrough research. Each research target needs input from two or more disciplines. Together, the nine targets link across disciplines, as a network that spans from genomic to planetary scales.Read moreRead less
Linkage Infrastructure, Equipment And Facilities - Grant ID: LE130100081
Funder
Australian Research Council
Funding Amount
$500,000.00
Summary
Spectral climate chamber facilities for phenomic studies of plant light response adaptation. Climates are changing, altering planting regimes in agriculture, and disrupting local adaptation in foundation species. The genetic basis of climate adaptation will be dissected in new plant growth facilities, equipped with real-time imaging and environmental controls that can mimic dynamic seasonal growing conditions and weather stress events.
