Interactions between an isolate of dark septate endophytes (DSE) and roots of Dendrobium nobile Lindl. seedlings are reported in this paper. The isolate was obtained from orchid mycorrhizas on Dendrobium sp. in subtropical forest. The fungus formed typical orchid mycorrhiza in aseptic co-culture with D. nobile seedlings on modified Murashige-Skoog (MMS) medium. Anatomic observations of the infe...

The response of plants to arbuscular mycorrhizal fungi involves a temporal and spatial activation of different defence mechanisms. The activation and regulation of these defences have been proposed to play a role in the maintenance of the mutualistic status of the association, however, how these defences affect the functioning and development of arbuscular mycorrhiza remains unclear. A number o...

Mycorrhizal symbiosis is a mutually beneficial association very commonly found among most vascular plants. Formation of mycorrhiza happens only between compatible partners and predicting this is often accomplished through a trial and error process. We investigated the possibility of using expression of symbiosis specific genes as markers to predict the formation of ectomycorrhiza. We used antib...

In this study, the effect of vermicompost and mycorrhizal fungi was investigated on growth, yield, chlorophyll pigments, leaf antioxidant enzymes, and seed silibinin content of Silybum marianum, milk thistle. The seeds were inoculated by two species of mycorrhiza fungi, Glomus mosseae and G. intraradices, and plants were irrigated and treated with 0, 25, 50, and 75% vermicompost after culturing...

Cd-tolerant bacterial strains of fluorescent pseudomonads, mostly belonging to Pseudomonas monteillii, were isolated from termite mound soil (Macrotermes subhyalinus, a litter-forager and fungus-growing termite), in a Sudanese shrubby savanna, Burkina Faso. Such large mounds appeared as sites of great bacterial diversity and could be considered as hot spots of metal-tolerant fluorescent pseudom...

in order to investigate the effect of rhizobium bacteria, mycorrhiza fungi and foliar application of urea on qualitative and quantitative traits of soybean an experiment was conducted based on randomized complete block design with four replications. the experiment included six treatments as: control (c), rhizobium bacteria (r), rhizobium bacteria + mycorrhiza fungi (r+m), rhizobium bacteria + f...

Rhizobium microbial bacteria functioning that living a symbiosis relationship soil and leguminous plant root fixation of nitrogen to be utilized by superior performance during grain development stage. They can enter into with plant, infecting their nodules. The legume crops are the bigger partner, often referred as macro-symbiotic. Usually certain strains form nodule on limited plants. Such col...

In order to study the effects of drought stress and mycorrhiza fungi on establishment rate and some growth-morphological traits ofZiziphora clinopodoides, pot experiments were conducted as factorial design based on a completely randomized design at the research greenhouse of agricultural faculty, Ferdowsi University of Mashhad in 2014; pots were combined as four levels of drought stress includi...
