Megan’s research interest is in the area of abiotic stress (salinity, drought) tolerance in agricultural crops. Of particular interest to her is the ability of the root system to adapt to abiotic stress and maintain growth, increasing root soil exploration for nutrient and water uptake. Her expertise includes root biology, plant physiology, plant biochemistry, molecular biology and functional genomics. Her current research aims to identify the molecular mechanisms that control and regulate root growth in response to salinity using barley (Hordeum vulgare L.) as a cereal model. The knowledge gained in barley will provide important information for increasing salinity tolerance in other Australian cereal crops, most notably wheat. We are also using an innovative technique, electrical impedance spectroscopy, to measure root growth in a number of wheat genotypes in response to salt-stress.
