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 کاملMycorrhizal fungi and nonhydraulic root signals of soil drying.
We propose that mycorrhizal colonization of roots alters nonhydraulic root to shoot communication of soil drying. Split-root rose (Rosa hybrida L. cv Samantha) plants-one side of the root system colonized by Glomus intraradices Schenck & Smith, the other side nonmycorrhizal-displayed different stomatal conductances upon partial drying, depending upon whether mycorrhizal or nonmycorrhizal roots ...
متن کاملCan Arbuscular Mycorrhizal Fungi Reduce the Growth of Agricultural Weeds?
BACKGROUND Arbuscular mycorrhizal fungi (AMF) are known for their beneficial effects on plants. However, there is increasing evidence that some ruderal plants, including several agricultural weeds, respond negatively to AMF colonization. Here, we investigated the effect of AMF on the growth of individual weed species and on weed-crop interactions. METHODOLOGY/PRINCIPAL FINDINGS First, under c...
متن کاملPlant coexistence mediated by arbuscular mycorrhizal fungi
Recent research has indicated the importance of arbuscular mycorrhizal fungi (AMF) in mediating plant coexistence. Coarse-scale studies compare the effects of the presence versus absence of AMF on plant coexistence, a phenomenon that is most relevant in early successional ecosystems where AMF are patchily distributed. By contrast, fine-scale studies investigate interactions that might occur onc...
متن کاملArbuscular mycorrhizal fungi of alfalfa root in the Kohgiluyeh & Boierahmad province (SW Iran)
In a study on AMF (Arbuscular Mycorrhizal Fungi) flora of alfalfa rhizosphere in Kohgiluyeh and Boierahmad province (SW Iran), 23 species belonging to nine genera: Acaulospora, Claroideoglomus, Diversispora, Entrophospora, Funneliformis, Gigaspora, Glomus, Septoglomus and Scutellospora, were identified.F. mosseae was the most abundant species. Also this is the first report of A. spinosa from Iran.
