Stuart Roy's research group focuses on creating crop plants that grow better on saline soils.
Loss of crop yield due to high concentrations of Na+ 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.
Our group has a number of projects all aimed at obtaining a better understanding of the processes involved in the transportation of Na+ through a plant and the mechanisms involved in activating such pathways.
