| The 450-million-year-old interaction between the majority of land plants and mycorrhizal fungi is one of the most ancient, abundant, and ecologically important symbiosis on earth. The early events in the evolution of mycorrhizal symbioses seem to have involved reciprocal genetic changes in ancestral plants and free-living fungi. new data on the mechanism of action of specific signaling molecules and how it influence and is influenced by the membrane ions fluxes and cytoplasm ion oscillations which integrate the symbiotic ionome are improving our understanding of the molecular bases of the mycorrhization process. This mini-review will highlight topics regarding what is known about the ionome and ionic communication in the arbuscular mycorrhizal symbiosis... |

| ABSTRACT The inoculation of arbuscular mycorrhizal fungi (AMF), increasing the rhizospheric influence, might provide higher levels of bioactive compounds. Thus, the objective was to evaluate the influence of the AMF inoculation on the physicochemical components of fruit’s quality in field. Strawberry fruits from cultivars Camarosa, Aromas, Camino Real, Monterey, Portola, San Andreas and Albion in 2016, and Camarosa, Camino Real, Monterey and Albion in 2017 were either inoculated or non-inoculated with AMF. The analyzed physicochemical components of fruit’s quality were ascorbic acid, titrated acidity, pH, soluble solids, soluble solids/titrated acidity ratio, phenolic compounds, anthocyanins, and firmness. The inoculation with AMF on strawberry plants in... |

| ABSTRACT: The objective of this study was to evaluate the effects of inoculation with different arbuscular mycorrhizal fungi native to Cerrado, associated with the application of colonization stimulant (7-hydroxy, 4’-methoxy-isoflavone) at the initial growth of cotton and maize plants in a greenhouse. The experiment was carried out in a completely randomized design and 7x2 factorial scheme, with five species of arbuscular mycorrhizal fungi and combined inoculation (uniting all species in equal proportion) and native fungi, in the presence and absence of colonization stimulant in maize and cotton crops. Shoots dry matter (SDM), roots dry matter (RDM), mycorrhizal colonization and accumulation of calcium, zinc and phosphorus in the SDM were evaluated at... |

| Un alto porcentaje de mortandad se presenta en pinos que son transplantados de vivero a campo, debido a que no poseen en sus raíces hongos ectomicorrízicos los cuales forman simbiosis obligada con los pinos de forma natural en los bosques. Estos hongos facilitan la absorción de nutrimentos y agua, además de estimular su crecimiento. Debido a la importancia de los hongos ectomicorrízicos, el presente trabajo evaluó el efecto en crecimiento, peso seco, porcentaje de colonización y contenido nutrimental de la inoculación de seis especies ectomicorrízicas comestibles de los géneros Laccaria y Hebeloma en Pinus patula y P. pseudostrobus, en condiciones de invernadero. Las especies inoculadas fueron previamente caracterizadas. Después de 397 días de la siembra... |

| O presente trabalho objetivou avaliar o efeito de fungos micorrízicos arbusculares (FMAs) na nutrição de mudas de acácia (Acacia mangium Willd.), sesbânia (Sesbania virgata (Cav.) Pers.) e eucalipto (Eucalyptus camaldulensis Dehnh.) em casa-de-vegetação, bem como a influência dos FMAs, do monocultivo e/ou consórcio sobre os teores dos nutrientes nas folhas das plantas em cava degradada pela extração de argila. Em casa-de-vegetação, mudas de acácia inoculadas com FMAs tiveram incrementos nos conteúdos de N, P e Zn de 22, 71 e 67%, respectivamente; as de sesbânia, de 39, 49, 56, 24, 105 e 54%, respectivamente para N, P, Ca, Mg, Mn e Zn. Na cava de extração de argila, plantas de acácia consorciadas com sesbânia apresentaram menor teor de Ca nas folhas. Ainda,... |

| ABSTRACT The use of cover crop in agricultural fields has been well elucidated, especially regarding nitrogen fixation from legume crops and their function as weed protection. Furthermore, to cover crops can benefit the soil microbial community. This study aimed to evaluate and compare the benefits of mulching and cover cropping systems on soil microbial growth and activity, and their effects on plant mineral nutrition in pomelo (Citrus maxima ) and macadamia ( Macadamia integrifolia ) orchards. The treatments included: 1) control [Glyphosate herbicide (Roundup at 4 l per ha)], 2) manual weed control, 3) mulching with dead leaves from their respective trees (macadamia and pomelo), 4) millet, 5) faba bean, 6) millet + faba bean. All the treatments were... |

| ABSTRACT Symbiosis between orchid seeds and mycorrhizal fungi has been reported to be a determining factor in the success of germination and protocorm development in vitro. The aim of this study was to isolate and identify by molecular analysis the mycorrhizal fungus associated with Cyrtopodium paludicolum, and to evaluate its efficiency in facilitating seed germination and development. Germination experiments were carried out using a fungus isolated from C. paludicolum (CH01) and Epidendrum secundum (M65), which has been successfully used a number of times in symbiotic germination. The experiments were conducted in a completely randomized design with treatments of CH01, M65 as well as under asymbiotic conditions. The mycobiont CH01 was successfully... |

| Each dipterocarp has its own species of fungus, forming an ectomycorrhiza. From literature and experiments (in East Kalimantan and in vitro) ecological consequences are explored. These help explain the clumping of dipterocarp trees in the forest, the lack of hybrids, the poor dispersal, and speciation as dependent on the viability of the root-fungus combination on a particular soil type. Mycorrhizas are located in the top soil. They are extremely sensitive to increase of soil temperatures as occur after canopy opening, and to soil compaction by machinery and log skidding. This explains the setback of dipterocarp growth after crude logging. It is suggested that avoidance of soil compaction during logging, quick restoration of soil cover, and the use of... |

| Determinou-se a ocorrência de fungos micorrízicos, pela contagem de esporos, em um solo dos Cerrados, nativo ou modificado pelo homen, com o objetivo de conhecer os efeitos de diferentes práticas agrícolas na ocorrência desses fungos. Amostrou-se solo sob vegetação de Cerrados e em áreas cuja vegetação foi substituída por pastagens puras de Brachiaria decumbens, e assim mantidas; ou que foi recuperada e mantida com fertilização a partir de 1993; ou área na qual se cultiva soja desde 1993, com diferentes sistemas de preparo de solo. Tomaram-se cinco repetições de solo em cada tratamento (0-20 cm de profundidade), nos períodos seco (setembro/2001) e chuvoso (janeiro/2002). Separaram-se os esporos usando-se a metodologia do peneiramento úmido, com malha de... |

| Mapuche farmers in southern Chile have been cultivating local ecotypes of chili pepper (Capsicum annuum L.), called locally Cacho de cabra for many decades. It is used to make merkén, a condiment that is consumed locally and exported. This vegetable requires a nursery stage and can obtain nutritional benefits from symbiotic associations such as mycorrhizal fungi, achieving a better adaptation to transplanting. Arbuscular mycorrhizal fungi (AMF) are obligate biotrophes appearing in abundance in agroecosystems with conservation management. The aim of this study was to compare effectiveness of two AMF, a commercial mycorrhizal inoculant (IC, Glomus intraradices) and another native (IN, Glomus claroideum) with a control without inoculation (-I) on the... |

| Abstract Spore counts, species composition and richness of arbuscular mycorrhizal fungi, and soil glomalin contents were evaluated in a soil contaminated with Zn, Cu, Cd and Pb after rehabilitation by partial replacement of the contaminated soil with non-contaminated soil, and by Eucalyptus camaldulensis planting with and without Brachiaria decumbens sowing. These rehabilitation procedures were compared with soils from contaminated non-rehabilitated area and non-contaminated adjacent soils. Arbuscular mycorrhizal fungi communities attributes were assessed by direct field sampling, trap culture technique, and by glomalin contents estimate. Arbuscular mycorrhizal fungi was markedly favored by rehabilitation, and a total of 15 arbuscular mycorrhizal fungi... |
