Prof. Schroeder pioneered the identification and characterization of many of the known major ion channel classes in plants and identified key ion channel regulation mechanisms. He developed the model for how these different plant ion channels function within a network towards controlling plant cell responses, in particular stomatal guard cell signal transduction, which regulates gas exchange and water loss from plants. His laboratory’s research also led to discovery of the HKT transporter genes, characterized their biophysical properties and discovered their functions in mediating salinity tolerance in Arabidopsis. This has led to breeders to molecular HKT marker-assisted breeding to enhance salinity tolerance in crops in the field. Julian Schroeder’s recent research is elucidating the ion channel regulation and signal transduction mechanisms and network that mediate resistance to drought in plants. Plants lose 95% of their water via stomatal pores. His research is elucidating the signal transduction mechanisms and network mechanisms in stomatal guard cells that mediate ion channel regulation in response to the drought stress hormone abscisic acid leading to stomatal closing and reduced water loss of plants. His recent research has further identified molecular and biophysical mechanisms by which the continuing elevation in the atmospheric CO2 concentration regulates guard cell ion channels, plant water loss and leaf heat stress.
