The immediate aim of Professor Tester's research program is to elucidate the molecular mechanisms that enable certain plants to thrive in sub-optimal soil conditions, such as those of high salinity or high temperature. In our research group, forward and reverse genetic approaches are used to understand and manipulate traits that contribute to salinity tolerance and improve this in crops such as barley, tomatoes and quinoa.
