Arbuscular Mycorrhiza (AM) comprises the mutual symbiotic relationship between soil born fungi of the order Glomales and an estimated 80% of all vascular plants. This symbiosis is necessary for plants grown on poor soil for scavenging nutrients, mainly phosphate and nitrogen and oligo elements. The establishment of this symbiosis, from spore germination of the biotrophic AM fungus to the colonization of the host root, depends on a well-balanced exchange of signaling compounds both of stimulatory and inhibitory nature.However, up to date no studies have investigated the role of secondary metabolite transporters, such as ABC transporters, in this context. We recently showed that the ABCG class transporter PDR1 from Petunia axillaris is responsible for the exudation of the phytohormone strigolactone from plant roots. Strigolactones act as a beacon to AM fungi, thus leading their hyphal branching towards the host root and letting the positive symbiosis start. At present we investigate the role and regulation of strigolactone transport in and outside plants. We aim to obtain a full view on strigolactone transport and target tissues thus to be able to regulate its activities in plant development and nutrient uptake.
