Postdoctoral position in Metabolic Signal Transduction/Biochemical Genetics
                Coruzzi Lab, New York University, Dept of Biology

The research focus of my lab concerns the molecular-genetic dissection of
nitrogen assimilation in Arabidopsis thaliana.  Our research projects focus
on the regulation of genes involved in assimilating nitrogen into the amino
acids glutamate, glutamine, aspartate and asparagine.  Arabidopsis mutants
defective in specific amino acid biosynthetic enzymes are being used to
define the rate-limiting enzymes involved in N-assimilation.  We are also
exploring the mechanisms by which light and/or metabolites ( carbon and
organic nitrogen) regulate the expression of particular genes in this
pathway.  Putative components of these light/metabolic signal transduction
pathways have been identified using both genetic and reverse genetic
approaches.  Two putative metabolic sensors isolated to date include a
plant PII-like protein and plant glutamate receptors which each appear to
be involved in aspects of metabolic signaling in Arabidopsis (see
references below).

Applications for a post-doctoral position should include a complete cv and
