Two new arbuscular mycorrhizal fungal species, (Glomeromycota) Septoglomus fuscum and S. furcatum, are described and illustrated. Spores of S. fuscum usually occur in loose hypogeous clusters, rarely singly in soil or inside roots, and S. furcatum forms only single spores in soil. Spores of S. fuscum are brownish orange to dark brown, globose to subglobose,(More)
A study was conducted to evaluate the aboveground biomass, nutrient content and the percentages of mycorrhizal colonization in Eucalyptus camaldulensis and Eucalyptus grandis plantations in the semiarid region (15° 09′ S 43° 49′ W) in the north of the State of Minas Gerais in Brazil. Results show that the total above-ground biomass (dry matter) was 33.6(More)
For the purpose of reforestation and wood supply the leguminous tree Anadenanthera peregrina, a native species, was intercropped with Eucalyptus camaldulensis in a degraded semiarid area of Brazil. Single and mixed stands of these species were inoculated with Rhizobium and/or arbuscular mycorrhizal fungi (AMF). The growth of all species in mixed stands did(More)
This paper investigates the distribution of arbuscular mycorrhizal fungi (AMF) spores and AMF colonization in a field study in southeastern Brazil. Response to AMF and rhizobial inoculation was studied in monocultures of Plathymenia reticulata and mixed plantations with both Tabebuia heptaphylla and Eucalyptus camaldulensis in a sandy soil during two(More)
Centrolobium tomentosum is a tropical legume tree indicated for functional and structural restoration of riparian areas. This study was conducted to characterize the rhizobia isolated from nodules of C. tomentosum in situ and to determine their capacity of renodulation, in an experimental area of land rehabilitation in the Rio Doce valley. Nodulation(More)
Interest in stressful conditions is rising with increasing the recognition that global changes can negatively affect plant diversity and ecosystem function. It is known that arbuscular mycorrhizas (AM) permit the plant to perform better under stressful and unfavorable conditions, recruiting their symbiont in the soil. Recent reports on plant growth under(More)
The purpose of this study was to evaluate the diversity of herbaceous plants and arbuscular mycorrhizal fungi following the cultivation of sunflower (Helianthus annuus L., cv. BRS 321) irrigated with produced water. The sunflower plants were irrigated during three successive cycles with different types of water: produced water obtained through simple(More)
In order to achieve a desirable ecological and sustainable agriculture a thorough understanding of the plant-soil mycobiome is imperative. Commercial industrial agriculture alters greenhouse gas emissions, promotes loss of plant and soil biodiversity, increases pollution by raising atmospheric CO2, and releases pesticides, thus affecting both terrestrial(More)
