Abstract:
Bibliography: leaves 161-178. This thesis characterises a mycorrhiza-defective tomato (Lycopersicon esculentum Mill.) mutant, rmc, with respect to fungal colonisation patterns and plant defence reactions during interactions with different species of arbuscular mycorrhizal (AM) fungi, root fungal pathogen Rhizoctonia solani and binucleate Rhizoctonia (a fungal parasite that colonises roots without causing disease). The results suggest that the mutated gene in rmc is involved in the regulation of recognition and plant defence responses in the establishment of AM symbioses.

Die arbuskuläre Mykorrhiza (AM) ist eine mutualistische Symbiose, die die Phosphataufnahme und Pathogenresistenz von Pflanzen verbessern kann. In der vorliegenden Doktorarbeit wurde die Rolle der Protonen-pumpenden ATPase MtHA1 für die AM Symbiose in Medicago truncatula untersucht. In MtHA1 Mutanten konnten AM Pilze nur noch verkürzte Arbuskel ohne typische Verzweigungen ausbilden. Dies zeigte sich auch in Expressionsmustern von Genen, die für Proteine in verschiedenen Bereichen der periarbuskulären Membran kodieren.

Abstract:
Members of the Orchidales produce dust seeds so lacking in nutrient and carbon reserves that they are dependent upon appropriate fungal partners to supply the essential additional carbon and nutrients required for successful establishment in nature. These plants are thus initially mycoheterotrophic before they normally go on to develop green leaves and become autotrophic as adults. However, at least 210 species of orchid remain fully mycoheterotrophic into adulthood. The metabolic pathways involved in the nitrogen and carbon fluxes from fungus-to -plant in mycoheteratrophic are still poorly un

Fluctuations in intracellular (Ca2+) calcium levels generate signaling events and regulate different cellular processes. Whilst the implication of Ca2+ in plant cell responses during arbuscular mycorrhiza (AM) interactions is well documented, nothing is known about the regulation or role of this secondary meesenger in the fungal symbiont. The molecular basis of fungal calcium homeostasis in the AM symbiosis was analyzed by investigating the expression of Ca2+-related fungal genes.

Abstract:
The Arbuscular mycorrhiza (AM) symbiosis is a mutual association formed by plant roots and soil fungi. Most vascular flowering plants have the ability to form AM associations, which show significant impact on ecosystem function and plant health. This association is based on the mutual exchange of nutrients between plant and fungus. Therefore, AM association leads to increased demands for photosynthesis. The main aim of this study was to investigate the pathway used by plants during AM to increase the photosynthetic performance. To achieve this aim, we used the model legume Medicago truncatula.

Several plant genes involved in the arbuscular mycorrhizal association have been identified in the past decade.

Abstract:
This study addressed the effects of salinity and pot size on the interaction between leguminous plant hosts and arbuscular mycorrhizal fungi in four pine rockland soils using a shade house trap-plant experiment. Little is known about the belowground diversity of pine rocklands and the interactions between aboveground and belowground biota – an increased understanding of these interactions could lead to improved land management decisions, conservation and restoration efforts. Following twelve weeks of growth, plants were measured for root and shoot dry biomass and percent colonization by arbusc

Abstract:
Os fungos micorrízicos arbusculares (FMA) têm papel fundamental na absorção de nutrientes, sobrevivência vegetal e na estruturação dos solos. Recentemente uma série de pesquisadores verificou que plantas associadas com FMA também podem se associar com os fungos de micélio escuro (DSE do inglês, dark septate endophytes). Embora de estudo recente, já se observou que os endófitos de micélio escuro igualmente podem promover o crescimento de plantas em diversos ambientes. O objetivo desse trabalho é realizar um levantamento de espécies de FMA e DSE em áreas de Mata Atlântica em um gradiente altitud
