Dr. Schultes is a molecular biologist studying aspects of metabolism in plants and disease causing microorganisms.

Education:A.B., Biology, Harvard University 1983
Ph.D., Department of Genetics, Harvard University Medical School 1990
Post-doctoral Fellowship, Biology, Yale University 1990-1994

Station Career:Assistant Scientist, 1994-2001
Associate Agricultural Scientist 2001-present

Past Research:Dr. Schultes has worked on the mechanism of gene conversion at the ARG4 locus in yeast, and cloning the gene encoding the large subunit of ribulose bisphosphate carboxylase from the cyanobacterium Fremyella diplosiphon.  Other research includes investigating the role of photorespiration in C4 photosynthesis in maize, using transposable element mutagenesis in maize genetics and studying the role of LHCB7 and PsbS genes in photosynthesis in the experimental plant Arabidopsis thaliana.

Current Research:

Dr. Schultes current work involves the genetics and molecular biology of nucleobase transporters in plants and disease causing microorganisms. The transport of nucleobases across biological membranes is essential to plant biochemistry. Nucleobases – also known as purines and pyrimidines - constitute the building blocks for DNA and RNA and are important molecules in plant nitrogen and secondary metabolism. Dr. Schultes and colleagues are also investigating nucleobase transporters from disease-causing bacteria Paenibacillus larvae and Erwinia amylovoraP. larvae is the causal agent of American foulbrood in honey bees and E. amylovora causes Fire blight on apples and pears.  In both organisms the transport of nucleobases and nucleobase-derivatives is involved in disease establishment.
