Mycorrhizal fungal identity and diversity relaxes plant-plant competition.
There is a great interest in ecology in understanding the role of soil microbial diversity for plant productivity and coexistence. Recent research has shown increases in species richness of mutualistic soil fungi, the arbuscular mycorrhizal fungi (AMF), to be related to increases in aboveground productivity of plant communities. However, the impact of AMF richness on plant-plant interactions ha...
متن کاملMycorrhizal fungal identity and richness determine the diversity and productivity of a tallgrass prairie system.
We investigated the effects of arbuscular mycorrhizal fungal (AMF) species richness and composition on plant community productivity and diversity, and whether AMF mediate plant species coexistence by promoting niche differentiation in phosphorus use. Our experiment manipulated AMF species richness and identity across a range of P conditions in tallgrass prairie mesocosms. We showed that increas...
متن کاملSerpentine Soils Do Not Limit Mycorrhizal Fungal Diversity
BACKGROUND Physiologically stressful environments tend to host depauperate and specialized biological communities. Serpentine soils exemplify this phenomenon by imposing well-known constraints on plants; however, their effect on other organisms is still poorly understood. METHODOLOGY/PRINCIPAL FINDINGS We used a combination of field and molecular approaches to test the hypothesis that serpent...
متن کاملFungal Diversity A novel technique for isolating orchid mycorrhizal fungi
We describe a technique for isolating mycorrhizal fungi from roots of orchids. This technique involves selection and treatment of roots, preparation of pelotons, treatment of pelotons, culture of pelotons so that fungal hyphae grow out and strain purification. The technique is considered better because 1) problems of fungal and bacterial contamination are resolved, 2) endophytic bacteria are su...
متن کاملDiversity of arbuscular mycorrhizal fungal spores associated with Sorbus torminalis (L.) Crantz
This study aimed to investigate the diversity and types of arbuscular mycorrhizal fungi (AMF) associated with the wild service tree, Sorbus torminalis (L.) Crantz in spring and autumn followed by identifying similarities among the different study sites. Three different sites were selected including Kheiroud, Lalis, and Tarkin, in the Hyrcanian forests, north of Iran. Five rhizosphere soil sampl...
