Research Themes

Scott's research is focused on the fundamental understanding of how plants physically and metabolically control their use of water, and how this has evolved over the past 400 million years since plants moved to land. Specifically, he studies how plant stomata work and are controlled by the environment. To do this, Scott employs a wide range of techniques, including measurements of plant gas exchange, water status, hormone levels, gene expression and molecular biology, as well as direct observations of stomata and plant anatomy. His work is conducted both in glasshouse experiments as well as in the field. 

The results of Scott's work extends beyond fundamental research by addressing the major global and social problem of future water security and the use of this resource by plants to improve agriculture. The topic of his research is aligned to the University's research theme area of Environment, Resources and Sustainability, and being underpinned by mathematical modelling and the processing of large data sets, it is also well aligned to the research theme area of Data, Knowledge and Decisions.

410 million years of stomatal evolution: key innovations in the transition from passive valves to active pores (2014 - 2016)$394,561
Description
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 insight 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.
