1. Mineral Nutrients and Plant-Fungal Interaction in Cocoa Trees (Theobroma cacao L.)
An infection of the fungus Moniliophthora perniciosa in cocoa trees reduces productivity of the plant. In this study, the concentrations of mineral nutrients in healthy leaves and in leaves of vegetative broom of the cocoa plant were determined, and the relationship between the disease and the nutritional composition of the leaves was assessed. The samples w

2. Effects of waterlogging stress on plant-pathogen interaction between Fusarium poae and wheat/ barley
ABSTRACT. Waterlogging stress is one of the abiotic factors which causes damage to crops affecting yield components and grain quality of wheat and barley. On the other hand, Fusarium poae is one of the most common Fusarium species isolated from wheat and barley. The aim of this study was to evaluate the effects of waterlogging and F. poae on disease paramete

3. Micro-organismos endofíticos e níveis de nitrogênio no crescimento de plantas de arroz
RESUMO Os micro-organismos endofíticos podem estimular o crescimento a depender da interação com a planta hospedeira e da disponibilidade de nutrientes no solo. O objetivo deste trabalho foi avaliar o crescimento de plantas de arroz BRS Tropical cultivadas com fungos endofíticos e níveis de adubo nitrogenado em estufa agrícola. O delineamento experimen

4. Compatibility and incompatibility in hyphal anastomosis of arbuscular mycorrhizal fungi
ABSTRACT: Arbuscular mycorrhizal fungi (AMF), which live in symbiosis with 80 % of plants, are not able to grow when separated from their hosts. Spore germination is not host-regulated and germling growth is shortly arrested in the absence of host roots. Germling survival chances may be increased by hyphal fusions (anastomoses), which allow access to nutrien

5. Host-exclusivity and host-recurrence by wood decay fungi (Basidiomycota - Agaricomycetes) in Brazilian mangroves
ABSTRACT This study aimed to investigate for the first time the ecological interactions between species of Agaricomycetes and their host plants in Brazilian mangroves. Thirty-two field trips were undertaken to four mangroves in the state of Pernambuco, Brazil, from April 2009 to March 2010. One 250 x 40 m stand was delimited in each mangrove and six categori

6. Endophytic Fungi as Novel Resources of natural Therapeutics
ABSTRACT Fungal endophytes constitute a major part of the unexplored fungal diversity. Endophytic fungi (EF) are an important source for novel, potential and active metabolites. Plant-endophyte interaction and endophyte -endophyte interactions study provide insights into mutualism and metabolite production by fungi. Bioactive compounds produced by endophytes

7. Screening and characterization of endophytic Bacillus and Paenibacillus strains from medicinal plant Lonicera japonica for use as potential plant growth promoters
Abstract A total of 48 endophytic bacteria were isolated from surface-sterilized tissues of the medicinal plant Lonicera japonica, which is grown in eastern China; six strains were selected for further study based on their potential ability to promote plant growth in vitro (siderophore and indoleacetic acid production). The bacteria were characterized by phy

8. Estabelecimento de um patossistema modelo e análise da interação molecular planta-patógeno entre Eucalyptus grandis e Puccinia psidii Winter por meio da técnica de RNA-Seq. / Establishment of a model pathosystem and analysis of the molecular plant-pathogen interaction between Eucalyptus grandis and Puccinia psidii Winter
More than 20 million hectares are destined to Eucalyptus plantations worldwide and Brazil has the second largest planted area. The International Eucalyptus Genome Network, EUCAGEN, was created in 2007 in order to perform genomic research on Eucalyptus. Brazil provided the biological material from the model tree (Brasuz) to have the complete genome sequenced

9. Expression of phenazine biosynthetic genes during the arbuscular mycorrhizal symbiosis of Glomus intraradices
To explore the molecular mechanisms that prevail during the establishment of the arbuscular mycorrhiza symbiosis involving the genus Glomus, we transcriptionally analysed spores of Glomus intraradices BE3 during early hyphal growth. Among 458 transcripts initially identified as being expressed at presymbiotic stages, 20% of sequences had homology to previous

10. Characterization of the dry bean polygalacturonase-inhibiting protein (PGIP) gene family during Sclerotinia sclerotiorum (Sclerotiniaceae) infection.
Polygalacturonase-inhibiting proteins are leucine-rich repeat proteins that inhibit fungal endopolygalacturonases. The interaction of polygalacturonase-inhibiting protein with endopolygalacturonases limits the destructive potential of endopolygalacturonases and may trigger plant defense responses induced by oligogalacturonides. We examined the expression of

11. 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

12. Natural products from endophytic fungi found in association with Asteraceae species and antibiotic assay in the "Caenorhabditis elegans" infection model / Produtos naturais de fungos endofíticos associados a espécies de Asteraceae e ensaio antibiótico no modelo de infecção em "Caenorhabditis elegans"
The search for small bioactive molecules from under-explored natural sources that possess specific ecological interaction in their respective habitat has been emphasized as strategic for the discovery of bioactive compounds. Endophytic microorganisms are still relatively under-explored sources of natural products. These microorganisms live inside the host pl
