1. Interaction of Fusarium solani, Macrophomina phaseolina and Rhizoctonia solani as root rot pathogens of Cucumis melo
RESUMO A ocorrência de doenças radiculares representa uma das principais causas de perda de rendimento na cultura do melão, com destaque para patógenos causadores das podridões de raízes e colo, como os fungos Fusarium solani (Fs), Macrophomina phaseolina (Mp) e Rhizoctonia solani (Rs), frequentemente observados no meloeiro de forma isolada ou associad

2. Isolation and molecular characterization of Rhizoctonia-like fungi associated with orchid roots in the Quadrilátero Ferrífero and Zona da Mata regions of the state of Minas Gerais, Brazil
Mycorrhizal associations can be considered required for orchids, which depend on the fungi for germination and establishment in natural conditions. Knowledge of the mycorrhizal fungi is important for programs aimed at the reintroduction, conservation and management of orchid species. The objective of this study was the molecular characterization of Rhizocton

3. Mycorrhizal diversity in Coppensia doniana (Orchidaceae) and phylogeny of mycorrhizal fungi associated with the Oncidiinae subtribe / Diversidade micorrízica em Coppensia doniana (Orchidaceae) e filogenia de fungos micorrízicos associados à subtribo Oncidiinae
In nature, orchids are fully dependent on mycorrhizal fungi for germination. These fungi can penetrate root cells and form pelotons, whose digestion provides simple sugars for the embryo. During the achlorophyllous seedling stage, orchids are obligatory dependent on the fungi, and some species remain so through life, while others become facultatively respons

4. Avaliação da expressão e caracterização de uma exo-ß-1,3-glucanase envolvida no mecanismo de micoparasitismo de Trichoderma asperellum
Species of the genus Trichoderma have been found to attack a wide range of plant-pathogenic fungi and have been used as biocontrol agents. The majority of Trichoderma preparations used commercially for biological control are Trichoderma atroviride or Trichoderma harzianum. However, Trichoderma asperellum, a less well studied species, is also an effective bio

5. Diversity and specificity of mycorrhizal fungi associated with Epidendrum secundum (Orchidaceae) in campo de altitude at State Park of Serra do Brigadeiro MG / Diversidade e especificidade de fungos micorrízicos associados a Epidendrum secundum (Orchidaceae) em um campo de altitude no Parque Estadual da Serra do Brigadeiro MG
In nature, species of Orchidaceae are always associated with mycorrhizal fungi. However, diversity of fungi associated to the orchids is little studied. Fungus-plant specificity has been observed and its comprehension is very important to establish programs for the simbiotic propagation of orchids. The objective of this work was to study the diversity and sp

6. Diversidade e potencial biotecnológico de fungos endofíticos de cacau (Theobroma cacao L.) / Diversity and biotechnological potential of the cacao (Theobroma cacao L.) endophytic fungi
Endophytes are all microorganisms, culturable or not, that inhabit the interior of plant tissues, causing no harm to the host, and that do not develop external structures, excluding in this way, nodulating bacteria and mycorrhizal fungi. Theobroma cacao L. is important to food and cosmetic industry due the fact that it is used for production of cacao butter.

7. Role of Two G-Protein Alpha Subunits, TgaA and TgaB, in the Antagonism of Plant Pathogens by Trichoderma virens
G-protein α subunits are involved in transmission of signals for development, pathogenicity, and secondary metabolism in plant pathogenic and saprophytic fungi. We cloned two G-protein α subunit genes, tgaA and tgaB, from the biocontrol fungus Trichoderma virens. tgaA belongs to the fungal Gαi class, while tgaB belongs to the class defined by gna-2 of Neu

8. The Global Regulator Genes from Biocontrol Strain Serratia plymuthica IC1270: Cloning, Sequencing, and Functional Studies†
The biocontrol activity of various fluorescent pseudomonads towards plant-pathogenic fungi is dependent upon the GacA/GacS-type two-component system of global regulators and the RpoS transcription sigma factor. In particular, these components are required for the production of antifungal antibiotics and exoenzymes. To investigate the effects of these global
