A postdoctoral position is available in the Department of Plant Sciences,
University of Arizona (http://ag.arizona.edu/PLS/ ), to study gene
silencing in petunia and arabidopsis, with emphasis on hierarchies of
homology-based control of anthocyanin gene expression and
resetting/remodeling of chromatin-based states of gene expression.
Applicants should send CV, statement of research accomplishments and
aspirations, and names of three references to Rich Jorgensen. Minimum
qualifications: Ph.D. in molecular genetics or related discipline.
Preferred qualifications: Experience in epigenetics, chromatin, and
transgene silencing in plants. Applications accepted until the position is
filled. University of Arizona is an EEO/AA Employer-M/W/D/V.
