Postdoctoral Positions in Chloroplast Biogenesis
2-3 postdoctoral positions will be available beginning September 1, 1994, to
use molecular genetic approaches to study two aspects of chloroplast biogenesis
in the unicellular eukaryotic alga Chlamydomonas reinhardtii.
In the first project, chloroplast transformation will be used to define
chloroplast transcript features that regulate translation initiation and mRNA
stability (see PNAS 90:497; EMBO J. 12:3627). Nuclear transformation will be
used to generate insertional mutations and to clone genes encoding trans-acting
proteins that regulate these processes.
In the second project, genetic approaches will be used to define components of
the chloroplast protein import pathway that interact with the transit peptides
of cytoplasmically synthesized precursors. This project will involve 1)
generating and testing transit peptide mutations in vivo and in vitro and 2)
isolating extragenic suppressors that can compensate for the transit peptide
The positions will be supported for a period of up to three years. Experience
in molecular biology and either protein biochemistry or genetics is required.
Qualified individuals should send a statement of research interests, curriculum
vitae, and the names, addresses and phone numbers of three references to:
