Post-doctoral positions are available in the laboratory of Dr. Sally
Assmann, Penn State University, for the study of signal transduction
pathways in Arabidopsis, as described in the references cited below.
Applicants should have expertise in at least one of the following areas: 1)
Arabidopsis molecular genetics; 2) cellular imaging; 3) RNA processing; 4)
electrophysiology. Applicants should send a CV, including contact
information for three references, to sma3 at

1. Positions are available in two parallel teams to work on an Arabidopsis
2010 project on G protein-coupled signal transduction.  Members of one team
require expertise in either fluorescent resonance energy transfer/cellular
imaging or electrophysiology; experience with Arabidopsis is helpful but
not required. Members of the other team require experience with both
Arabidopsis and molecular genetics.

2. Positions are available to study dynamic ABA regulation of RNA
processing in Arabidopsis. One aspect of the project (in collaboration with
Prof. Philip Bevilacqua, )
requires expertise in RNA structure, metabolism, or splicing, or other
evidence of strong molecular and biochemical skills; another aspect of the
project requires expertise in cellular imaging.
