Postdoctoral Fellowship -- Plant Molecular Biology, Cornell University.
A position is available to investigate the molecular processes controlling
fruit development using tomato and arabidopsis as model systems. Successful
candidate should have demonstrated experience in molecular biology and an
interest in development.
Background: Fruit-bearing domesticated plants are taxonomically diverse, yet
they all share a common feature --the edible portion of the plant (ovaries)
has undergone a tremendous increase in size and shape variability (up to
1000 x) compared with their wild progenitors. For example, the wild
ancestors of cultivated tomato bear fruit weighing only a few grams. In
contrast, a single fruit from a modern tomato variety may contain many
ovaries and weigh up to 1000 gms. Until recently it was difficult, if not
impossible, to identify the genes controlling fruit growth since this is a
polygenic trait. Using a QTL approach, we have mapped most of the loci
controlling both fruit size and shape in tomato (PNAS 93:15503, Grandillo et
al, in press) and have begun to clone them (two have been isolated thus far,
Frary et al, in prep, Ku et al, in prep) and to study their
regulatory/developmental/interactive properties and to investigate the role
of homologous genes in other plants,, including arabidopsis.
The successful candidate will join a team of approximately 10 graduate
students and postdocs working on related projects and will have access to a
large infrastructure of genomic and computational tools available at Cornell
University (http://www.genomics.cornell.edu/). There will also be
opportunities to become familiar with microarray technology for transcript
analysis, bioinformatics and various genetic approaches (including QTL
analysis) for gene isolation and functional analyses.
Applicants should send or e.mail curriculum vitae and names and e.mail
addresses of at least 3 references to Dr. Steven Tanksley
