A postdoctoral research position is available immediately to study the 
regulation of metal uptake in Arabidopsis.  We are studying the 
regulation of the Arabidopsis genes IRT1 and FRO2, which respectively 
encode the major high affinity iron transporter and the inducible ferric 
chelate reductase enzyme responsible for iron uptake from the soil. 
Previously, we determined that IRT1 is subject to post-transcriptional 
regulation by metals (The Plant Cell 14(6): 1347-1357); evidence 
suggests that IRT1 may be subject to metal-induced ubiquitination and 
removal from the plasma membrane.  We also have shown that expression of 
FRO2 is regulated post-transcriptionally by iron (Plant Physiol. 
133:1102-1110).  Our current studies are designed to elucidate the 
molecular mechanism(s) controlling regulation of IRT1 and FRO2 by 
metals. A thorough understanding of the regulation of the iron uptake 
machinery will be essential for the creation of food crops with enhanced 
nutrient content.

A Ph.D. and a background in molecular biology and genetics are required. 
Interested candidates should send a cover letter, CV, reprints or 
preprints and the names, addresses and FAX numbers of three references

applications/inquiries are preferred.
