Further root colonization by arbuscular mycorrhizal fungi in already mycorrhizal plants is suppressed after a critical level of root colonization.
An established arbuscular mycorrhizal symbiosis suppresses further mycorrhization. It is not clear whether the observed suppressional effect is linked with the level of root colonization or not. In the present work we studied the effect of the degree of root colonization by the arbuscular mycorrhizal fungus Glomus mosseae on further root colonization by G. mosseae. At different time points barl...
متن کاملInoculation with arbuscular mycorrhizal fungi suppresses initiation of haustoria in the root hemiparasite Pedicularis tricolor.
BACKGROUND AND AIMS Plant parasitism and arbuscular mycorrhizal (AM) associations have many parallels and share a number of regulatory pathways. Despite a rapid increase in investigations addressing the roles of AM fungi in regulating interactions between parasitic plants and their hosts, few studies have tested the effect of AM fungi on the initiation and differentiation of haustoria, the para...
متن کاملEffects of Arbuscular Mycorrhizal Fungi on Growth and Nutrient Uptake of Apple Rootstocks in Calcareous Soil
The effects of three Arbuscular Mycorrhizal Fungi (AMF) species (Glomus versiforme, Claroideoglomus etunicatum and Rhizophagus intraradices) were studied on the growth parameters and nutrient uptake of three apple rootstocks (M.9, M.7 and MM.106). The soil medium contained a high level of calcium carbonate (38.65%). The results showed that AMF inoculation could increase almost all growth parame...
متن کاملArbuscular 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 determined. With fungi of both genera, a correlation between the number of entry points and the perce...
متن کاملAre there benefits of simultaneous root colonization by different arbuscular mycorrhizal fungi?
Arbuscular mycorrhizal fungal (AMF) communities were established in pots using fungal isolates from a single field in Switzerland. It was tested whether multispecies mixtures provided more phosphorus and supported greater plant growth than single AMF species. Two host plants, medic (Medicago truncatula) and leek (Allium porrum), were inoculated with three AMF species (Glomus mosseae, G. claroid...
