Exploration of model systems to study mycorrhizal symbiosis on roots of forest trees

Abstract : Mycorrhizal fungi supply soil minerals, particularly phosphorus and nitrogen, to the host plants, the plants reward them with carbohydrates. During the ectomycorrhizal symbiosis Populus tremulax albathe phosphate transport appears to be carried out by two specific transporters, PhT1.9and PhT1.12.Some trees like poplar, chestnut and Tremacan form symbiosis with two mycorrhizal fungi, ecto-and endomycorrhiza. It was demonstrated for the first time that chestnut can form endomycorrhizal symbiosis.Trema is close relative of Parasponiawhich can develop symbiosis with arbuscular mycorrhiza and also with rhizobia. Tremaand Parasponiaare sequenced, transcriptome data are available. Parasponiais easy to propagate by regeneration, transformed, and transformation of Tremais under very intensive investigation. All these make Trema-Parasponiavery attractive model to study ectomycorrhizal symbiosis in the connection to two other symbiosises, endomycorrhizal and rhizobial
