Flavonoid metabolism in Arabidopsis seed

A PhD position is available to work on genetic, molecular, and  
biochemical analyses of flavonoid metabolism in Arabidopsis seed.
Location: Seed Biology Laboratory, INRA Versailles, France  

The two major end-products of the flavonoid pathway that are  
encountered in Arabidopsis seeds are proanthocyanidins (PAs; syn.  
condensed tannins) and flavonols. PAs accumulate specifically in the  
seed coat (or testa), giving the mature seed its brown color after  
oxidation. On the other hand, flavonols (colorless to pale yellow  
products) are found not only in the testa but also in the embryo and  
endosperm. A genetic approach based on the isolation and  
characterization of seed color mutants has enabled to identify most of  
the presently known genes involved in the flavonoid pathway.  
Nevertheless, many unknown functions remain to be discovered,  
especially in relation to flavonoid biosynthesis, compartmentation,  
condensation and oxidation. Transcriptomic analysis of mutants and  
transformants have been initiated recently in our laboratory to  
identify novel functions not accessible directly through a genetic  
approach. The successful student will develop complete functional  
analyses of candidate genes and corresponding mutants using molecular,  
genetic, biochemical and cytological approaches.

Funding is available for three years, beginning December 2005. The  
deadline for application is October 15, 2005. Applications are invited  
from highly motivated students with interests in plant biology. Basic  
skills in molecular biology would be a plus.
Additional informations on eligibility criteria can be obtained at  

Please send your application including a cover letter (research  
interests and experience), a detailed CV and letters from two  
scientific referees to Isabelle Debeaujon (debeaujo at versailles.inra.fr).
