Повний текст джерелаIn the first part of the thesis, possible effect of the plant genotype on the genetic diversity and structure of the arbuscular mycorrhizal (AM) fungal community was assessed. Results indicated a similar diversity of AM fungi in the four Medicago species used. However, the abundance of AM fungi differed significantly upon the plant species, indicating preferential associations between AM fungal and plant genotypes. The second part of the thesis was based on the hypothesis that the long joint evolution of AM fungi and plants did not occur independently of the associated bacteria. To test this hypothesis, the genetic structure of bacterial communities associated with mycorrhizal and non mycorrhizal roots of M. Truncatula was compared. The bacterial communities differed significantly between mycorrhizal and non mycorrhizal roots, these differences being explained by sequences belonging to Oxalobacteraceae and Comamonadaceae families. Six bacterial isolates representative of the populations belonging to Oxalobacteraceae and Comamonadaceae were tested together with two reference strains (Collimonas fungivorans Ter331 and Pseudomonas fluorescens C7R12) for their effect on mycorrhization. One strain belonging to Oxalobacteraceae (Collimonas sp. J5B4) and P. Fluorescens C7R12 promoted both AM fungal growth and mycorrhization, partially confirming our hypothesis that bacteria preferentially associated with mycorrhizal roots would be beneficial to the symbiosis. Finally, the characterization of the promoting effect of P. Fluorescens C7R12 showed that it was fungal specific and that the pattern of colonization of bacterial cells on mycorrhizal and non mycorrhizal roots differed

Повний текст джерелаThe actual contribution of arbuscular mycorrhizal (AM) fungi to plant nutrient uptake depends on the fungal and plant genomes, and on environmental conditions. In the present study, AM fungi of different origin, for example isolated from plots with different long-term fertilizer application history, were used to quantify their contribution to plant nutrient uptake under situations of spatially heterogeneous soil nutrient distribution. Test plants for this study were sweet potato and marigold. Several model experiments were carried out. In specifically constructed growth containers, non-mycorrhizal and mycorrhizal sweet potato plants were supplied with organic matter either homogeneously or heterogeneously distributed in the substrate. Bacteria from a long-term organically fertilized soil were also added as a treatment. In other experiments using a split-root approach, the influence of AM fungi on the plant response to localized mineral phosphorus and nitrogen supply was studied. In a further experiment, the effects of localized compost supply on marigold plants inoculated with Glomus mosseae were investigated. Arbuscular mycorrhizal fungi increased nutrient uptake and growth of plants under most conditions, also when nutrients were heterogeneously distributed in soil. However, there was no indication of increased hyphal proliferation or activity in soil spots with high organic matter. Plant phosphorus status regulated the extent of AM root colonization. The extent of AM root colonization was partly decreased by application of organic matter and of compost to the substrate. Application of organic matter and/or compost can be beneficial in horticulture and can replace mineral fertilizer use. However, optimum plant growth and mycorrhizal function require a good balance between type and amount of organic matter or compost, growth substrate properties and plant and AM fungal genotype.

Повний текст джерелаEven though arbuscular mycorrhizal fungi (AMF) are present from foothills to all alpine habitats, research on their role in mountain ecosystems remains incomplete. The main objective of this dissertation was to investigate interactions between AMF and plants along altitudinal gradients under both, natural conditions and simulated future climate change conditions.A novel framework is suggested for the functioning of the AMF-plant relationship along altitudinal gradients based on the stress gradient hypothesis. The first hypothesis expects the AMF-relationship to shift along the mutualism–parasitism continuum following changing environmental stress along the altitudinal gradient. The relationship might be most mutualistic at the subalpine zone. In a second hypothesis, this shift along the mutualism-parasitism continuum is predicted to be different under climate change conditions, and the most mutualistic expression of the AMF-plant relationship expected in the montane and alpine zone. Studies to validate the presented hypotheses will help to identify important mechanisms underlying plant-AMF interaction and with that the mediation of plant-plant interactions by AMF. In the scope of this thesis, the framework was addressed in field experiment as well as under controlled conditions in a climate chamber experiment.From a literature review and from a field experiment along a dry inner-alpine altitudinal gradient this thesis proposes the following conclusions: First, AMF are also ubiquitous in mountain ecosystems, but a decrease in their abundance with increasing altitude is dependent on the overall climatic context. Second, their relationship to plants is however strongly dependent on the host plant species as well as the biotic and abiotic context. Third, a shift of the AMF-relationship along with altitude is expected but will quite possibly also depend on the plant species identity. Fourth, to fully assess the suggested working hypotheses for AMF-plant interactions field studies must be conducted at different spatial scales and covering different mountain systems.It is particularly important to understand and investigate the drivers of AMF plant relationship in mountain ecosystems to be able to make sound predictions for AMF-plant interactions under future climate change conditions. The presented field and climate chamber experiments on climate change show that temperature is an important factor because it aggravates the conditions of drought in lowland and a threshold is surpassed. It becomes also clear that whether AMF mitigate climate change effects for plants or not is dependent on the plant species. Altogether this thesis contributes to current research questions in ecology, climate change mitigation and plant–soil interactions, because it addresses the role of AMF in mountain grassland ecosystem, investigates the effects of climate change and provides a new framework concerning the functioning of the AMF-plant relationship ranging from parasitism to mutualism
Zhang, Haoqiang. "Arbuscular mycorrhiza in Medicago truncatula." Doctoral thesis, Humboldt-Universität zu Berlin, Landwirtschaftlich-Gärtnerische Fakultät, 2014. http://dx.doi.org/10.18452/16925.
Повний текст джерелаArbuscular mycorrhiza (AM) is a wide spread mutualistic symbiosis, which can improve phosphate acquisition and pathogen resistance of plants. In the current Ph.D. thesis the role of a proton pumping ATPase (MtHA1) for the AM symbiosis in Medicago truncatula was investigated. In MtHA1 mutant plants, different AM fungi only developed truncated arbuscules without forming typical hyphal branches, and this phenotype was mirrored by expression patterns of genes for proteins located in different areas of the periarbuscular membrane. AM fungal colonization, improved phosphate uptake and plant growth promotion were reduced in MtHA1 mutant plants. Mycorrhiza-induced resistance (MIR) and the nodule symbiosis were, however, not affected. MIR was further analyzed in the M. truncatula infected with Aphanomyces euteiches which causes a root-rot disease in legumes. In a split root system showing high levels of defense-gene expression, colonization of an AM fungus reduced this expression and in consequence increased susceptibility of the roots for the pathogen. In roots of pot cultures, however, a typical MIR was observed and could be based on the higher activity of jasmonate/ethylene-regulated defense responses due to suppression of salicylic acid biosynthesis. In conclusion, this work shows that the gene MtHA1 encoding a proton pumping-ATPase plays a critical role in the formation and function of arbuscule-containing cells. Expression of the mutated gene results in reduced formation of arbuscule branches. This in turn negatively influences mycorrhizal phosphate uptake, plant growth promotion and overall mycorrhizal colonization of the roots. Gene expression analyses indicate that different mechanisms underlay local and systemic interactions between the mycorrhizal fungus and the root pathogen. The different physiological stages of pot culture and split root system make a comparison of the two experimental approaches, however, difficult.

Повний текст джерелаTo study the impact of AM inoculation on fruit production, three commercially grown strawberry cultivars (Glooscap, Joliette, and Kent) were not inoculated with AM fungi or were inoculated with either G. intraradices or G. mosseae. AM fungi impacted the fruit yield, with all inoculated cultivars producing more fruit than noninoculated cultivars during the first harvest year. The percentage of root colonization could not be used to explain the differences in total fruit yield during the first harvest year, or the increase in total fruit yield the second harvest year.
We wished to examine the effects of various P treatments on C metabolism within the intraradical mycelia (IRM) of the fungus. Specific primers were developed for the Glomus intraradices glucose-6-phosphate dehydrogenase (G6PDH) gene. Real-time quantitative reverse transcriptase polymerase chain reaction (QRT-PCR) was used to measure the gene expression of the G. intrarardices G6PDH gene in response to external P conditions of colonized transformed carrot roots. The results showed a significant down-regulation of G6PDH in the IRM of G. intraradices when cultures were grown in a high P (350 muM P) medium compared to those grown in the low P (35 muM P) medium. The down-regulation may suggest a reduction in the C flow from the host to the fungus. There was no effect on G6PDH expression following a two-hour incubation with additional P applications (No P, low P and high P).

Повний текст джерелаThe plant hormones ethylene and ABA are probably key developmental regulators of arbuscular mycorrhizae (AM). The first objective of this work was to evaluate the development of MA in overproducing and insensitive mutants to ethylene (epinastic and Never ripe, respectively) and verify if enzymes related to plant defense system are differentially regulated by ethylene during the symbiosis development. The colonization of epinastic (epi) roots by G. clarum was significantly reduced when compared with Micro-Tom (MT), moreover, the functionality of the symbiosis as demonstrated by transcripts accumulation of LePT4, was strongly reduced when compared with MT. Still, the pattern of colonization and functionality of the symbiosis in the Nr mutant did not differ from MT. Induction in the transcripts accumulation of genes encoding chitinase and enzymes related to oxidative stress was observed in epi mutant, whereas transcripts accumulation of -1, 3-glucanase was strongly induced in the Nr mutant. The second objective was to determine whether the reduced colonization observed in mutants deficient in ABA is dependent on ethylene production. For this purpose, mutants that differ in ABA deficiency and produce different amounts of ethylene (notabilis and sitiens) and the epi mutant were inoculated with G. clarum and treated with an ethylene inhibitor called aminoethoxivinilglicin (AVG). The intraradical colonization of G. clarum in epi and notabilis (not) mutants was significantly reduced when compared with MT and sitiens mutant was less susceptible to colonization in comparison with other genotypes. The application of AVG to 10 µM completely restored the colonization in the epi but not in mutants deficient in ABA. The transcripts accumulation of LePT4 confirmed the results of colonization. The genes that encode key enzymes in the biosynthesis of ethylene, LeACS2 and LeACO4, were positively regulated by inoculation with G. clarum and the restoration in the development of MA observed in epi which received AVG probably involved ACC oxidase (LeACO4). Transcripts accumulation of genes that encode ACC oxidase (LeACO1 and LeACO4) were induced significantly in sit showing that overproduction of ethylene in this mutant can involve ACC oxidase. Finally, the induction in the accumulation of gene transcripts LeNCED was observed in all genotypes and mycorrhizal roots of epi which received AVG demonstrating that LeNCED is regulated positively by the inoculation with G. clarum and that ethylene regulates the expression of this gene. Results show that ethylene and ABA are involved in regulating of MA development and ethylene modulates the expression of genes related to the plant defense system allowing the establishment and functionality of the symbiosis.

Повний текст джерелаIn der arbuskulären Mykorrhiza (AM) Symbiose werden die Wurzeln fast aller Landpflanzen von Pilzen der Abteilung Glomeromycota besiedelt. Der Pilz erleichtert der Pflanze die Aufnahme von Mineralien, hauptsächlich Phosphat, und Wasser. Im Gegenzug versorgt die Pflanze ihn mit Photoassimilaten. Trotz der zentralen Bedeutung der Austauschmechanismen zwischen Pilz und Pflanze ist nur wenig darüber bekannt. Um die molekularen Grundlagen der Interaktion zwischen den Wurzeln der Leguminose Medicago truncatula und dem arbuskulären Mykorrhizapilz Rhizophagus irregularis besser zu verstehen, werden hier die Transportprozesse, die zwischen den Symbiosepartnern ablaufen, näher untersucht. Die zellspezifische Regulation der Transkription potentieller M. truncatula Transporter Gene in arbuskelhaltigen und nicht-arbuskelhaltigen Zellen mykorrhizierter Wurzeln wird bestätigt. Ein Modell zur möglichen Verteilung von Kohlenhydraten in mykorrhizierten Wurzeln, nach dem Zucker in nicht-arbuskelhaltigen Zellen mobilisiert und symplastisch an arbuskelhaltige Zellen abgegeben werden, wird vorgestellt. Die Analyse eines Mykorrhiza-induzierten Hexose/H+ Symporter Gens, MtHxt1, liefert neue Einsichten in die Mechanismen der Kohlenhydratverteilung in mykorrhizierten Pflanzen. Metabolitanalysen von Wurzeln und Blättern einer knock-out Mutante dieses Gens zeigen dessen Einfluss auf den Kohlenhydrathaushalt der ganzen Pflanze und auf die Interaktion mit dem Pilz. Die Metabolitzusammensetzung von M. truncatula wird durch die Mykorrhiza Symbiose signifikant beeinflusst. Darüber hinaus werden durch Transkriptomanalysen die molekularen Grundlagen der AM Symbiose auf der Seite des Pilzes analysiert. Arbuskeln wurden mittels Laser Capture Mikrodissektion direkt aus mykorrhizierten Wurzeln isoliert. Über 3200 pilzliche Transkripte weisen in diesen Arbuskeln im Vergleich zu extraradikalen Geweben ein deutlich verändertes Expressionslevel auf. Unter diesen Transkripten sind auch sechs zuvor unbekannte Gene, die für potentielle Transporter codieren und mit großer Wahrscheinlichkeit eine Rolle im Nährstoffaustausch zwischen Pilz und Pflanze spielen. Während die Substrate von drei potentiellen MFS Transportern noch unbekannt sind, spielen zwei potentiellen Zuckertransporter möglicherweise eine Rolle im Transport von Kohlenhydraten in Richtung des Pilzes. Zusammengefasst bietet diese Arbeit neue Einsichten in Transportprozesse zwischen Pilz und Pflanze im Laufe der AM Symbiose. M. truncatula Transkript- und Metabolitlevel werden analysiert und die Transkriptomanalyse von R. irregularis liefert einen umfassenden Datensatz mit einer großen Menge an Informationen zu der noch unzureichend erforschten pilzlichen Seite der Symbiose für folgende Arbeiten.

Повний текст джерелаFarmers and technicians involved with organic citriculture try to develop systems with high microbial activity in soil. In this way, they expect to obtain benefits from processes that occur in soil, as natural control of pests and diseases. However, there are few studies about the influence of this type of management on soil microbiota, specially on the arbuscular mycorrhizal fungi (AMF) and the pathogen Phytophthora parasitica. The objectives of this thesis were: to evaluate mycorrhizal colonization and diversity of AMF in citrus conventional and organic farming; to evaluate benomyl application and γ radiation to obtain non-mycorrhizal controls for study of interaction between indigenous AMF and P. parasitica; to verify local and systemic capacity of indigenous AMF to induce resistance against P. parasitica; to study chitinase activity in roots of 'Rangpur' lime colonized by indigenous AMF. Samplings were carried out in two citrus systems in São Paulo, one conventional and one organic farming. The richness and the diversity of AMF species were higher in the organic farming. In greenhouse, experiments with 'Rangpur' lime (Citrus limonia) showed that γ radiation was better than benomyl to obtain non-mycorrhizal control for studies of interaction between P. parasitica-indigenous AMF from orange agroecosystems. In greenhouse also, a split root experiment with 'Rangpur' lime was carried out. It was not possible to evaluate the indigenous AMF capacity to induce resistance because no root rot developed in 'Rangpur' lime plants after inoculation with P. parasitica. We discuss the interaction between root pathogens in natural soil and indigenous AMF because natural soil from conventional e organic farming promoted different local and systemic root growth responses in mycorrhizal plants. Chitinase activity was similar in roots of mycorrhizal and non-mycorrhizal plants grown in conventional and organic farming soils. However, mycorhizal association increased local protein content in roots.
