title: In vitro co-culture of two AMF isolates Gigaspora margarita and Glomus intraradices on Ri T-DNA transformed roots.
abstract: An in vitro system using Ri T-DNA transformed carrot roots as the host bearing simultaneously different arbuscular mycorrhizal (AM) fungi belonging to two genera Glomus intraradices (Smith and Schenck) and Gigaspora margarita (Becker and Hall) was developed. Co-existence appeared healthy and harmonious, as both the generic species showed extensive hyphal proliferation and sporulation. The co-culture model under the in vitro system appears especially appropriate for further investigations on the competition and on the interaction mechanism involved in such types of associations occurring in nature and also as a model approach towards mass production of multiple mycorrhizal fungal isolates. This is a first report of successful co-culture of two genera of AM fungi under in vitro conditions.
