Objective

Soils contaminated with Cs pose a long-term radiation hazard to human health. Indeed, the chemical similarity of Cs and K constitutes the major threat to the contamination of the above-ground vegetation and incorporation in the food-chain as root uptake mechanisms appear closely related for these elements. Rhizospheric processes involving soil micro-organisms are known to influence radiocaesium root uptake. Among these, the obligate arbuscular mycorrhizal (AM) fungal symbionts are expected to play a key role due to their intimate position at soil/root interface.

Recently, the role of AM fungi in Cs transport to the roots has been evidenced. Furthermore, it has been demonstrated that AM fungi can influence Cs root to shoot translocation by affecting Cs root transport. A recent hypothesis attributed to abscisic acid a primary role in restricting this transport. With this in view, the objective of the present proposal is to elucidate the mechanisms involved in the transport of Cs by AM fungi to the root and translocation from roots to shoot, leading to the evaluation of the radioecological significance of AM fungi on the accumulation of Cs in plants and to propose implementations of present bioremediation strategies. To achieve this goal five major fields of training, i.e. microbiology, molecular biology, biophysics, plant physiology and radioecology, will be considered.
