Arbuscular mycorrhizal colonization of tomato by Gigaspora and Glomus species in the presence of root flavonoids

The effect of flavonoids isolated from arbuscular mycorrhizal (AM) colonized and noncolonized clover roots on the number of entry points and percentage of root colonization of tomato (Lycopersicum esculentum L.) by Gigaspora rosea, Gi margarita, Glomus mosseae and G. intrarradices symbionts was dete...

These results indicated that flavonoids could be implicated in the process of regulation of AM colonization in plant root, but its role is highly complex and depend not only on flavonoids, but also on AM fungal genus or even species. © 2005 Elsevier GmbH.
