PROPOSAL FOR A JOINT POST-DOC BETWEEN THE LABORATOIRE DE ZOOLOGIE INRA IN
RENNES AND THE LABORATOIRE DE ZOOLOGIE INRA-INSA IN LYON

TITLE: Molecular characterization of populations and role of the
aphid-Buchnera symbiosis in the host preference of the cereal aphid
Sitobion avenae.

Aphid symbiosis (obligate intracellular symbiosis with a Buchnera
proteo-Bacteria) is crucial to adaptation of aphids to phloem feeding, an=
d
probably to host-plant adaptation.
A post-doc position is available immediately, on a net monthly basis of
ca. 9000 F. It is part of a Human Capital & Mobility Network (EU funded,
95-96) on Aphid Biology and Symbiosis. Part of funding also comes from
INRA (French Natl. Agronomic Institute).
Work will involve:
1- Rennes: molecular characterization of clonal populations of Sitobion
avenae adapted to different cereal hosts, by the means of nuclear,
mitochondrial and symbiotic DNA probes (developed partly in the present
European network).
2- Lyon: metabolic characterization of a selected subset of the previousl=
y
analyzed clones. Focus will be put on amino-acid metabolism and the
symbiotic influence on the anabolic capacities (analysis of aposymbiotic
aphids, diagnostic tool of free amino-acid pools, radioactive labeling of
amino-acid precursors).
Additional information will be sent to interested persons.
Suitable for a non-French European citizen (and to =AB assimilated =BB
persons, for example east-European citizen working in a EU laboratory
outside France).
Proposed post-doc position for one year in two periods and locations: INR=
A
Rennes and INRA-INSA Lyon.
