POSTDOCTORAL POSITION: Gibberellin Signaling in Arabidopsis
Department of Biology, Duke University

A postdoctoral position is available immediately to study "Gibberellin  
Signaling in Arabidopsis."  We are looking for a highly
motivated individual who has an excellent background in protein  
chemistry, genetics, genomics, molecular biology or plant development.

Bioactive gibberellins (GAs) are a class of plant hormones that  
modulate diverse developmental processes throughout the life cycle of  
a plant.  The nuclear DELLA proteins are highly conserved negative  
regulators of GA signaling that act immediately downstream of the GA  
receptors GID1 to repress GA-mediated growth in Arabidopsis and in a  
number of crops.  GA signal appears to de-repress its response pathway  
by triggering degradation of these repressor proteins.  To understand  
how GA controls plant development, we are using biochemical and  
genomics approaches to elucidate the signaling events immediately  
downstream of DELLA.
