Arbuscular mycorrhizal (AM) fungi are widespread root symbionts that often improve the fitness of their plant hosts. We tested whether local adaptation in mycorrhizal symbioses would shape the community structure of these root symbionts in a way that maximizes their symbiotic functioning. We grew a native prairie grass (Andropogon gerardii) with all possible combinations of soils and AM fungal ...

Hairy root culture of tomato (Lycopersicon esculantum L.) was induced with three strains of Agrobacterium rhizogenes namely A4, ATCC 15834 and LBA 9402. The best response in terms of growth of hairy root was observed with A. rhizogenes strain A4 and LBA 9402 followed by ATCC 15834. Hairy roots were maintained on Murashige and Skoog (MS) medium but it could also grow on minimal (M) medium. Spore...

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.

Pennisetum pedicellatum plants were inoculated with Glomus mosseae, G. aggregatum and Gigaspora margarita. There were both quantitative and qualitative changes in the protein pattern of inoculated plants. Gi. margarita induced increase in protein in the plants. Acid phosphatase, alkaline phosphatase, superoxide dismutase and chitinase activities were high at the beginning of infection, but decl...
