Dr Stuart Roy
Stu is a Senior Research Fellow in the Plant Genomics Group at the School of Agriculture, Food & Wine, University of Adelaide. His interests are in improving the abiotic stress tolerance of cereals crops, particularly salinity tolerance, and in improving cereal yield.
Stu gained a BSc (Hons) in Plant and Environmental Biology for the University of St Andrews (UK) and a PhD in Plant Physiology from the University of Cambridge (UK). After a Broodbank Research Fellowship at Cambridge, Stuart moved to the Australian Centre for Plant Functional Genomics, University of Adelaide, to lead the Salinity Research program. He continues this program today in the School of Agriculture, Food and Wine.
Loss of crop yield due to high concentrations of Na+ and Cl- on agricultural land is a significant problem for Australian farmers. An estimated 4.6 M ha of Australian farmland is affected to some degree by saline soils - currently 1 in 2 Western Australian farms and 1 in 5 South Australian farms are affected by salinity. By 2050 it is expected that around 14 M ha of Australian agricultural land will be affected by dryland salinity, therefore it is imperative that we identify genes and cellular processes which will increase the salinity tolerance of our crop plants.
Crops undergoing salt stress experience an immediate reduction in growth and tillering (shoot independent ionic stress) and an increase in premature senescence due to the accumulation of toxic ions (shoot dependent ionic stress).
Our group has a number of projects all aimed at obtaining a better understanding of the processes involved in both the shoot independent and the shoot dependent ionic stress. We are using both forward and reverse genetics to identify mechanisms for improving the salinity tolerance of crops.
