In Vitro Compartmented Systems to Study Transport in Arbuscular Mycorrhizal Symbiosis

With the development of compartmented systems allowing the separation of the mycorrhizal roots from the extraradical mycelium, studies on arbuscular mycorrhizal (AM) fungal transport have been performed since the middle of the 1970s. They rapidly led to the demonstration that AM fungi can transport nutrients to their hosts. While soil-based systems were initially used and continue to be widely employed, AM fungal transport is also commonly studied with in vitro culture systems, as they offer distinctive advantages.
