Full textIn its environment, the plant interacts constantly with microorganisms. It is confronted with a variety of beneficial, neutral or pathogenic microorganisms, which are highly dependent on the carbon resources that the plant releases into the soil, giving them a supply of nutrients and energy necessary for their development. The arbuscular mycorrhiza is a mutualistic symbiosis formed by 80% of terrestrial plants from the Ordovician period, i.e. about 450 million years ago. The research presented in this manuscript was focused on two main goals: (i) to gain a better understanding of the mechanisms underlying trophic relationships in the mycorrhizal plant, and (ii) to study the impact of mycorhization on plant production, both in terms of quantity and quality. We investigated the mycorrhizal response of wheat landraces in order to understand if there were differences in a semi-controlled environment (greenhouses) or in an uncontrolled environment (field), and / or depending on the community of mycorrhizal fungi. Our results showed that mycorrhization and the nature of endogenous arbuscular mycorrhizal fungi can affect yield, even in wheat varieties with low mycorrhizal ability. We also highlighted the importance of choosing the criteria used to measure this potential gain. In a second line of research, we were interested in the impact of arbuscular mycorrhiza on the development of Micro-Tom tomato, and the trophic exchanges during the interaction. Multivariate analysis revealed behavioral differences between plants at mature green fruit and red ripening stages depending on arbuscular mycorrhizal fungal strain, as well as potential interaction event between two arbuscular mycorrhiza fungus trains. Our results confirm that the arbuscules are not the only sites of exchange in arbuscular mycorrhiza. The third axis of this work focused on the potential impact of seed production methods of ancient tomato varieties in drought condition, both on the endogenous community of arbuscular mycorrhizal fungi in the field, on the tolerance of the plant to water stress and on crop production in terms of fruit yield and quality. The experimental site was located in the Potager de santé (seed farm managed by Pascal Poot). Our results show no difference, under conditions of water stress in the field, between varieties regularly cultivated on this site and commercial varieties. Then, one may wonder if other factors related to the exploitation site, such as the beneficial microorganisms interacting with the roots of the plants could be at the origin of the increased tolerance to water stress. Work is underway in the laboratory to study this hypothesis. All of this work paves the way for new research aimed at elucidating the molecular mechanisms involved in the regulation of trophic exchanges during arbuscular mycorrhizae and the valuation of the ecosystem services rendered by arbuscular mycorrhizae in the field

Full textArbuscular mycorrhizal fungi are an important group of microorganisms in the rhizosphere because of their ubiquity in terrestrial ecosystems and the symbiotic association that they form with more than 80 % of plant species. Mycorrhizas improve plant mineral nutrition as weIl as resistance to environmental stress. However, little is known on the diversity of these fungi in soil, either at an inter or intraspecific level, and on the relationship between diversity and function. The objectives of the thesis were (1) to set up molecular tools to study the diversity of AM fungi and (2) to caracterise the populations of AM fungi in 3 soils amended with different levels of sewage sludge using these tools. First, species richness and spore abondance were estimated. The same 6 species were found in the three soils. Spore abundance was lower in the plot which received the highest sludge amendment, which could be related to the modification of soil parameters due to the amendments (heavy metals, pH,. . . ). Two molecular techniques (PCR fingerprinting using a microsatellite primer, analysis of the small sub-unit ribosomal DNA using PCR) were developped, validated and applied with isolates of Glomus mosseae from collection cultures. These techniques were used to study the populations of the 2 most abundant species found in the studied soils (Glomus geosporum-like and Glomus claroideum ). A high intraspecific variability was observed for both species and for both of them the populations of the three soils were genetically different. A high structuration of the populations was observed, although the samples were only distant of a few meters. The mechanisms involved in the high diversity remains to be explained, but data analysis suggests a clonal reproduction and also recombination events. Finally, the host-plant as weIl as the soil influence the intraspecific diversity of G. Claroideum

Full textThe use of arbuscular mycorrhizal fungi (AMF) could be an innovative alternative to chemicals against fungal plant diseases. Our work aimed at studying the possible protective effect of arbuscular mycorrhization in the bread wheat (Triticum aestivum L.) against Blumeria graminis f. sp. tritici (Bgt), a biotrophic fungi responsible of wheat powdery mildew, a disease affecting the aerial plant organs. Wheat mycorrhizal inoculation by Funneliformis mosseae (Fm), under controlled and optimized conditions, allowed us to obtain concomitantly a micorrhizal rate of 38%, a significant increase of plant biomass and a protection level against Bgt estimated at 78%. These results suggest the induction of systemic wheat defense reactions resulting from mycorrhization (Mycorrhiza-Induced Resistance - MIR). This protection is linked to an accumulation of phenolic compounds and hydrogen peroxide at the Bgt penetration sites in epidermal leaf cells of mycorrhized wheat plants. Up-regulations of POX, PAL, NPR1 and CH11 genes encoding for defense markers were also pointed out in leaves of mycorrhizal wheat in the absence of Bgt infection. Moreover, our study highlighted the importance of taking into account various parameters to optimize the use of AMF as biocontrol agents. The highest protection against powdery mildew was obtained with a 5-fold reduced phosphorus input compared to that recommended in the field and with the mycorrhizal inoculum Fm, in both a moderately susceptible or a more resistant cultuva

Full textParasitic weeds such as broomrapes (Orobanche spp. ) can cause severe damage on crop plants, and efficient and sustainable control methods are needed. The aim of our work was to determine whether symbiotic micro-organisms called arbuscular mycorrhizal fungi can be used as a biocontrol method to protect sunflower against Orobanche cumana. We first observed that mycorrhization of sunflower plants reduced significantly their infection by Orobanche cumana. We then showed that mycorrhizal sunflower root exudates induced lower Orobanche cumana seed germination than non-mycorrhizal root exudates. Moreover, we demonstrated for the first time that AM fungi alone could produce inhibitors of Orobanche seed germination. Finally, we set up a novel in vitro system in which the early stages of sunflower root infestation by Orobanche cumana can be monitored. This system could be used to investigate possible effects of mycorrhizal fungi on these different stages

Full textThe arbuscular mycorrhizal symbiosis, which appeared at the same time as land plants, 460 million years ago, is a mutualistic beneficial association between most land plants, including those cultivated, and arbuscular mycorrhizal fungi (AMF). AMF, from the Glomeromycota phylum, are widespread soil microorganisms needing a photosynthetic host to complete their life cycle (obligate symbionts). The great potential of plant mineral nutrition improvement and crop production increased during this symbiosis, make AMF an asset in the context of an increase in the demand of world food crop production. The control of that symbiosis by ecology engineering in order to improve ecosystem services, especially in agroecosystems, needs to better understand the mechanisms regulating its dynamic. Therefore, we studied community and population diversity of AMF under influences of different agricultural practices at several spatial scales using genetic fingerprinting methods: high-throughput sequencing and restriction fragment length polymorphism. Results show that AMF diversity is structured by land use type (grassland vs. arable fields), cultural practices (soil disturbance, fertilizations, culturing systems) as well as environmental factors (e.g. soil pH). In conclusion, those different factors have to taken in account in AMF ecosystemic service managing

Full textRare earth elements (REE) are a group of strategic metals that have been widely used in modern technologies in the recent decades. However, due to the corresponding REE emission from industries and the over-exploitation, large amounts of anthropogenic rare earth can accumulate in the environment, and be phytotoxic. Arbuscular mycorrhizae (AM) benefit to plants in metal-contaminated soils by improving their survival and growth and alleviating metal toxicity, but little information is available about soil contaminated by rare earth elements. The objective of this PhD project is to understand the transfer of REEs from soil to plants and especially the role of AM fungi on plant growth and REE transfer to plants in REE contaminated soils. Experiments were launched using a model legume plant alfalfa (Medicago sativa), a model REE samarium (Sm), and a metal-tolerant Funneliformis mosseae fungus in a growth chamber. We first studied the bioavailability and transfer of an REE to Medicago sativa grown on two contaminated soils differing in their chemical characteristics. The results showed that DTPA extractable Sm was well correlated with Sm uptake in alfalfa shoots. Although the soil to plant transfer factor was low, alfalfa biomass was reduced when the soils were spiked with 100 to 200 mg kg-1 of Sm. Then the hypothesis was drawn that arbuscular mycorrhizal fungi might protect the plant against REE toxicity. Therefore, a pot experiment was launched to study the role of AM fungi on alfalfa growth and a compartment experiment was performed to study the transfer of Sm to alfalfa via AM fungal hyphae. The biomass of alfalfa grown on Sm-spiked soil was significantly higher following arbuscular mycorrhiza inoculation. P content was also higher in mycorrhizal than nonmycorrhizal plants, but there was no significant Sm transfer to the plant by F.mosseae. Since there are often multiple REEs in contaminated soils, including light (LREE) and heavy (HREE) REEs, a compartment experiment was launched using 4 REEs, alfalfa and ryegrass, which confirmed that there was no transfer of the 4 REEs to alfalfa plants by F.mosseae. Finally, an REE mining soil collected from China was used to analyze the toxicity of REEs to AM fungal spores and to leek plants inoculated or not with the AM fungus, using spore germination assays and a plant growth experiment. The high concentration of REEs significantly inhibited plant growth and spore germination rate, and the fungus tolerated relatively high REE concentrations, but there was no significant difference in REE tolerance between two isolates of F.mosseae. Other fungi and plants should be tested, and field experiments performed, but our results suggest that arbuscular mycorrhizal plants might be considered in phytorestoration of REE-contaminated soils

Full textAccumulation of trace metals, such as cadmium (Cd), in soils and their transfer to plants are serious environmental problems because of their acute toxicity. Metal mobility in soil depends on various abiotic and biotic factors. Among them, arbuscular mycorrhizal (AM) fungi are known to influence metal transfer by transporting metals to roots and also by improving plant growth. However, diverging results were reported and the global role of AM fungi thus needed more investigation. The influence of an AM fungus (Glomus intraradices) on Cd uptake and transfer to leachates was studied with Medicago truncatula as a host plant. Experiments were performed in pot cultures and in compartmented devices. The dynamic of Cd in the soil-plant system was indirectly influenced by the fungus via a strong increase of plant biomass, in interaction with nodulating rhizobacteria, leading to a higher total quantity of Cd transferred to shoots although Cd plant concentration was lower than in non mycorrhizal plants. This fungal influence was complex, and was variable according to soil conditions and to the fungal isolate studied. The AM fungus also contributed directly to Cd transfer thanks to its sorption capacity and its ability to transport soluble-exchangeable Cd via the extraradical mycelium, but this direct contribution seemed to be low as compared to the influence of roots
