Infection by Arbuscular Mycorrhizal Fungus Glomus Mosseae of Leek Plants (Allium Porum L.): Effect On Lipids

Abstract

It is well recognized that mycorrhizal symbiosis is highly beneficial to plant growth and protection from disease (Strullu, 1991). In arbuscular mycorrhizae, a highly intimate relationship is created between symbionts by the intracellular differentiation of arbuscules that represent a critical site for plant-fungi interactions. Several experiments have demonstrated that metabolites, such as carbon, minerals, and phosphate can be exchanged between mycorrhizal symbionts. In order to investigate whether lipids may be exchanged between plant and fungal symbionts, analysis of fatty acids and sterols were performed from leek plants (roots, bulbs and leaves), colonized and non-colonized with Glomus mosseae, as on isolated spores of this species.
