A post-doctoral postion is currently available for an individual with a
background in plant molecular biology to study molecular aspects of cell
wall biosynthesis in Arabidopsis.
We have recently identified a mutant of Arabidopsis that is defective in the
gene encoding ferulate-5-hydroxylase (F5H) (Chapple et al., 1992. Plant
Cell 4:1413-1424), one of the genes of the general phenylpropanoid pathway
that has not yet been cloned. As a result of this mutation, the monomer
composition of the lignin in the mutant's secondary cell wall is
dramatically altered, and resembles the lignin normally seen in gymnosperms.
We have identified a T-DNA tagged mutant in which the T-DNA insertion
appears to be directly within the coding sequence of the F5H gene. Our
immediate goals are to use the T-DNA tagged line to retrieve cDNA and
genomic clones encoding F5H, confirm their identity by complementation of
the original EMS-induced mutants, and to study the effect of ectopic- and
over-expression of F5H on secondary cell wall biochemistry.
Experience in molecular biology is essential, and experience with
biochemical techniques such as gas chromatography is desirable. Interested
individuals should submit a CV and the names and addresses of 3 references,
and are encouraged to do so by electronic mail if possible. Purdue
