The project aims to analyse how the circadian clock provides adaptive advantages in legumes and cereals, two major crop groups of global importance. The project expects to produce new fundamental knowledge about how the clock in these crops coordinates their development, physiology, and metabolism in response to environmental cues. The anticipated outcome is a better understanding of key similarities and differences in clock functions in different species. Another is knowledge of how the ancient clock gene variants still in use today may limit the current or future performance of those crops. This will provide significant benefits, such as to improve productivity of crop plants in diverse and changing environments.Read moreRead less

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

New genetic mechanisms linking flowering, growth habit and yield in legumes. This project aims to investigate the genetic control of flowering and flowering-related traits in legumes, an important group of crop plants. The regulation of flowering by environmental factors has a major influence on plant yield and is important for adaptation in natural and agricultural settings. However, it is poorly understood at the molecular level.

This project aims to investigate the genetic control of flowering and flowering-related traits in legumes, an important group of crop plants. The regulation of flowering by environmental factors has a major influence on plant yield and is important for adaptation in natural and agricultural settings. However, it is poorly understood at the molecular level. This project aims to use induced genetic variation and transcriptome analysis to define new genes and genetic mechanisms through which flowering is regulated by day length and temperature, and to explore the molecular links between flowering and other developmental processes including seed development. This should extend our understanding of how plant architecture, reproduction and yield are regulated by the environment, and address several agronomic issues.Read moreRead less
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

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.

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

This project proposes a new approach to understand the evolution and physiology of stomatal function, and how this interacts with xylem evolution to determine whole-plant water management. Using a combination of membrane-level, and whole-leaf physiological techniques, this project will focus on mechanisms of stomatal closure in diverse plant species. Specific stomatal and xylem responses to water stress will be mapped together onto the gymnosperm clade to reveal co-evolutionary linkages between xylem and stomatal physiology. By combining physiological data with evolutionary patterns among major land plant lineages this project will produce a mechanistic framework for interpreting the drought ecology of all plant species.Read moreRead less
Seaweed forests of the future: responses to ocean acidification and warming. The aim is to discover if rising levels of oceanic carbon dioxide will offset negative effects of ocean warming on seaweeds, using targeted physiological experiments together with novel molecular diagnostics.

The aim is to discover if rising levels of oceanic carbon dioxide will offset negative effects of ocean warming on seaweeds, using targeted physiological experiments together with novel molecular diagnostics. Seaweeds create habitats and food for shellfish and fish, and play a crucial role in long term ‘blue carbon’ storage. They are predicted to benefit from future carbon dioxide enrichment, but to test this forecast requires a detailed understanding of the mechanisms used by seaweeds to acquire dissolved inorganic carbon. The expected outcome is robust predictions of how the primary productivity of coastal waters will respond to future high carbon dioxide conditions, enabling human adaptation to environmental change.
