DESCRIPTION:Julian Schroeder’s research is directed at elucidating signa
 l transduction mechanisms and pathways that mediate resistance to environm
 ental abiotic stresses in plants linked to water. Water-linked stresses ha
 ve substantial negative impacts and reduce plant growth. His research is e
 lucidating the mechanisms mediating gas exchange regulation in plants via 
 stomatal pores through which plants lose 95% of their water via transpirat
 ion. His seminar will focus on characterization of mechanisms mediating st
 omatal closing in plants in response to drought and elevated atmospheric C
 O2.  Newly identified stomatal guard cell signal transduction mechanisms m
 ediated by drought\, the stress hormone abscisic acid and the continuing r
 ise in atmospheric CO2 will be described. In addition\, identification of 
 mechanisms through which elevated CO2 down-regulates the stomatal developm
 ent machinery will be presented. In his early research Julian pioneered th
 e identification and characterization of many of the known major ion chann
 el classes in plants and key ion channel regulation mechanisms in plants. 
 He developed the model for how these different plant ion channels function
  within a network towards controlling plant cell responses\, in particular
  guard cells\, which regulate stomatal apertures in plants.\n
