1. Seed exudates of Sesbania virgata (Cav.) Pers. stimulate the asymbiotic phase of the arbuscular mycorrhizal fungus Gigaspora albida Becker & Hall
RESUMO Sesbania virgata é uma leguminosa utilizada na restauração de áreas degradadas e que forma simbiose com fungos micorrízicos arbusculares (AMF). Suas sementes exudam metabólitos secundários que podem influenciar a colonização pelos AMF. Neste trabalho, estudamos os efeitos de exsudatos de sementes (SE) e radiculares (RE) de S. virgata na fase

2. The role of mycorrhization helper bacteria in the establishment and action of ectomycorrhizae associations
More than 95 % short roots of most terrestrial plants are colonized by mycorrhizal fungi as soon as they emerge in the upper soil profiles. The establishment of mycorrhizal association involves profound morphological and physiological changes in root and fungus. It is affected by other rhizospheric microorganisms, specifically by the bacteria. Bacteria may h

3. Óleo essencial de eucalipto como bioestimulador da micorrização e do estabelecimento de mudas de eucalipto e sibipiruna em solo contaminado com cobre / Essential oil of eucalyptus as biostimulator of mycorrhiza and the eucalyptus and sibipiruna tree establishment in soil contaminated with copper
Ectomycorrhizal fungi (fECM) combined with the plant root system improve the absorption of water and nutrients, providing great plant growth, especially in environments with nutritional deficiency or degraded. Due to the fECM and plants live in mutualistic association, allows the fungal symbionts to be benefit, or at least tolerate, the secondary metabolites

4. Riqueza de fungos micorrÃzicos arbusculares no solo e o crescimento inicial de espÃcies arbÃreas nativas / Arbuscular mycorrhizal fungi richness in soil and the initial growth of native wood species
Os mecanismos que controlam e mantÃm a diversidade, a produtividade primÃria e a estrutura das comunidades de plantas ainda nÃo foram completamente elucidados. Tem sido sugerido que os fungos micorrizicos arbusculares (FMAs) desempenham papel importante nas comunidades vegetais, mas hà carÃncia de provas experimentais comprobatÃrias desta funÃÃo. No

5. Efeito do cobre sobre fungos micorrÃzicos e trevo vermelho (Trifolium pratense L.)
The effects of copper on arbuscular mycorrhizal (AMF) and ectomycorrhizal fungi (EMF) and on the symbiosis between AMF and plants of Trifolium pratense L were evaluated. Species diversity, most probable number (MPN) of propagules and production of glomalin by AMF were estimated in a copper mining area (a- waste product area; b- interface between the waste pr

6. Fungal Growth Stimulation by CO2 and Root Exudates in Vesicular-Arbuscular Mycorrhizal Symbiosis
Transformed roots of carrot were used to determine the effects of root metabolites on hyphal development from spores of the vesicular-arbuscular mycorrhizal fungus Gigaspora margarita. Hyphal growth of this obligately biotrophic symbiont was greatly stimulated by a synergistic interaction between volatile and exudated factors produced by roots. Root volatile

7. Seven Lotus japonicus Genes Required for Transcriptional Reprogramming of the Root during Fungal and Bacterial SymbiosisW⃞
A combined genetic and transcriptome analysis was performed to study the molecular basis of the arbuscular mycorrhiza (AM) symbiosis. By testing the AM phenotype of nodulation-impaired mutants and complementation analysis, we defined seven Lotus japonicus common symbiosis genes (SYMRK, CASTOR, POLLUX, SYM3, SYM6, SYM15, and SYM24) that are required for both

8. The endophytic fungus Piriformospora indica reprograms barley to salt-stress tolerance, disease resistance, and higher yield
Disease resistance strategies are powerful approaches to sustainable agriculture because they reduce chemical input into the environment. Recently, Piriformospora indica, a plant-root-colonizing basidiomycete fungus, has been discovered in the Indian Thar desert and was shown to provide strong growth-promoting activity during its symbiosis with a broad spect

9. Influence of Vesicular-Arbuscular Mycorrhizal Fungi on the Response of Potato to Phosphorus Deficiency.
Morphological and biochemical interactions between a vesicular-arbuscular mycorrhizal (VAM) fungus (Glomus fasciculatum [Thaxt. sensu Gerdemann] Gerdemann and Trappe) and potato (Solanum tuberosum L.) plants during the development of P deficiency were characterized. Nonmycorrhizal (NM) plants grown for 63 d with low abiotic P supply (0.5 mM) produced 34, 52,

10. The Glyoxylate Cycle in an Arbuscular Mycorrhizal Fungus. Carbon Flux and Gene Expression
The arbuscular mycorrhizal (AM) symbiosis is responsible for huge fluxes of photosynthetically fixed carbon from plants to the soil. Lipid, which is the dominant form of stored carbon in the fungal partner and which fuels spore germination, is made by the fungus within the root and is exported to the extraradical mycelium. We tested the hypothesis that the g

11. The Ectomycorrhizal Fungus Laccaria bicolor Stimulates Lateral Root Formation in Poplar and Arabidopsis through Auxin Transport and Signaling1[W]
The early phase of the interaction between tree roots and ectomycorrhizal fungi, prior to symbiosis establishment, is accompanied by a stimulation of lateral root (LR) development. We aimed to identify gene networks that regulate LR development during the early signal exchanges between poplar (Populus tremula × Populus alba) and the ectomycorrhizal fungus L

12. Carbon Uptake and the Metabolism and Transport of Lipids in an Arbuscular Mycorrhiza1
Both the plant and the fungus benefit nutritionally in the arbuscular mycorrhizal symbiosis: The host plant enjoys enhanced mineral uptake and the fungus receives fixed carbon. In this exchange the uptake, metabolism, and translocation of carbon by the fungal partner are poorly understood. We therefore analyzed the fate of isotopically labeled substrates in
