Arbuscular Mycorrhizal Fungal Assemblages in Conservation Unit of Atlantic Forest Areas Under Native Vegetation and Natural Regeneration.

Arbuscular mycorrhizal fungi (AMF) play an important role in the dynamic of plant community in the south American Atlantic Rainforest biome. Even in protected areas, this biome is under several anthropic impacts, which can cause shifts in the soil microbiota, including AMF. This study aimed to determine the structure and composition of AMF community in areas of native Atlantic Forest and in natural regeneration and to identify which abiotic factors are influencing this community in these areas.

Mycorrhizal inoculation as an alternative for the sustainable production of Mimosa tenuiflora seedlings with improved growth and secondary compounds content.

In this study, we report the effects of arbuscular mycorrhizal fungi (AMF) and increasing doses of phosphorus (P) on the growth and production of secondary metabolites in Mimosa tenuiflora, a medicinal species native to Brazil. We used a completely randomized design with four inoculation treatments: Control not inoculated (1); Claroideoglomus etunicatum (2); Gigaspora albida (3); and C. etunicatum + G.

Application of Arbuscular Mycorrhizal Fungi during the Acclimatization of to Induce Tolerance to .

An experiment was conducted to evaluate the tolerance of micropropagated and mycorrhized alpinia plants to the parasite . The experimental design was completely randomized with a factorial arrangement of four inoculation treatments with arbuscular mycorrhizal fungi (AMF) (, , , and a non-inoculated control) in the presence or absence of with five replicates. The following characteristics were evaluated after 270 days of mycorrhization and 170 days of inoculation: height, number of leaves and tillers, fresh mass of aerial and subterranean parts, dry mass of aerial parts, foliar area, nutritional content, mycorrhizal colonization, AMF sporulation, and the number of galls, egg masses, and eggs.

Responses of Guava Plants to Inoculation with Arbuscular Mycorrhizal Fungi in Soil Infested with Meloidogyne enterolobii.

In the Northeast of Brazil, expansion of guava crops has been impaired by Meloidogyne enterolobii that causes root galls, leaf fall and plant death. Considering the fact that arbuscular mycorrhizal Fungi (AMF) improve plant growth giving protection against damages by plant pathogens, this work was carried out to select AMF efficient to increase production of guava seedlings and their tolerance to M. enterolobii.
