Postdoctoral Position: Mechanisms of Iron Acquisition in Grasses. E. 
L. Walker Lab, University of Massachusetts, Amherst.  A postdoctoral 
position is available for up to three years starting June, 2005. Our 
main interest is in the mechanisms that higher plants use to acquire 
iron from the soil and then allocate it correctly into cells and 
tissues. We began this work with cloning and characterization of 
maize YS1, which is responsible for primary iron uptake by the 
world's major grain crops (rice, wheat, corn). These species use a 
mechanism of iron acquisition that is fundamentally different from 
that of most other plants.  In this project, we will examine both the 
extrusion of phytosiderophores-the strong iron chelators produced 
only by grasses-and their re-uptake into cells, using genetic and 
molecular genetic techniques in maize and rice.  For additional 
details, and to discuss the application process, please contact 
Elsbeth Walker (ewalker at bio.umass.edu).
