In Reunion Island, pineapple crops are exposed to high parasitic pressure promoted by the subtropical climate of the island. The Fruitlet Core Rot (FCR) disease is caused by a set of fungal pathogenic species in which Fusarium ananatum has been the most described so far. The development of brown discoloration in mature fruits represents a major issue affecting notably the quality of the ‘Queen Victoria’ pineapple cultivar due to its high susceptibility to FCR. Until now, the management of epidemics lies on the combination of suitable agricultural practices and the use of fungicide treatments. Nevertheless, these strategies are unsuccessful in the presence of climatic conditions that favor the development and dispersion of causalagents. Mycotoxins accumulation in the flesh of infected fruits is also of concern in the preservation of sanitary quality of fruit productions. In order to develop novel alternatives for sustainable sources of FCR resistance, my research work focused on the determinants of ‘Queen Victoria’ pineapple susceptibility. An epidemiological approach permitted to establish that Fruitlet Core Rot occurrence ispositively correlated to contamination patterns resulting from aerial dispersion of the pathogen spores. Moreover, the prevalence of fungal species belonging to the complexes Fusarium fujikuroi and Talaromyces purpureogenus within the fruit mycobiome have demonstrated the role of a pathogenic fungal set composed of Fusarium proliferatum, Fusarium ananatum, Fusarium oxysporum, Fusarium sacchari, Talaromyces stollii and Talaromyces amestolkiae in the disease expression. The in vitro study of interaction profiles between four of those species have evidenced the growth antagonism of T. stollii on the pathogenic Fusarium species. Significant variations of mycotoxin contents (fumonisins B1, B2 and beauvericin) were also measured during dual culture of pathogens. Finally, the analysis based on varietal comparison of the molecular signal promoting early defense responses show that susceptibility of ‘Queen Victoria’ cultivar is partly supported by a low constitutive expression of genes involved in the synthesis of PR proteins. The results suggest a fungal strategy based on the repression of defense signal transduction in pineapple during the first 72 hours of the host - pathogen interaction leading to the disease establishment

Fruiltet core rot (FCR) disease affects the fruits of mature pineapples. Current disease controls are not available. A deeper knowledge of the pathosystem is needed to find an effective means of control FCR.A diagnostic survey conducted with producers during the southern winter revealed a prevalence of the disease of 74%. Pathogenic fungi belong to several species: Fusarium ananatum (72% isolates), Talaromyces stollii (21%), F. oxysporum (6%) and F. proliferatum (1%). Their toxinogenic potential was determined. Fusarium fungi produced mycotoxins identified as fumonisins FB1, FB2 and beauvericin. On a pineapple culture medium, a concentration of beauvericine of 34959 μg kg-1 was measured for the species F. proliferatum.A method of inoculating Fusarium ananatum directly into the parenchyma allowed to describe the biochemical response of the fruit. The phenylpropanoids pathway is involved, particularly with the elicitation of caffeoylisocitrate and coumaroylisocitrate in the infected zone. A comparison of the metabolic profiles shows that the response to inoculation of resistant cultivar 'MD-2' is higher than in the sensitive cultivar 'Queen'. Most of the metabolites elicited by the attack are already present in healthy mature fruits of the resistant variety. The antifungal potential of the phenolic compounds was evaluated. Coumaric, caffeoylquinic and ferulic acids inhibit mycelial growth at concentrations similar to those found in infected fruits.An imaging approach allowed to describe the anatomy of the fruits of the two cultivars, to identify the key roles played by nectaries and carpel margins in the infection and colonization process of Fusarium ananatum

An extensive study was undertaken to characterize 94 isolates of Xanthomonas campestris pv. Mangiferaeindicae responsible for bacterial black spot of mangoes. Studies on carbohydrates assimilation, susceptibility to antibiotics and to heavy metal salts, serotyping and phage-typing, plasmid patterns as well as to pathogenicity to several hosts have revealed a large variability within the isolates. Biological and epidemiological studies of the pathogen under Reunion Island conditions have allowed us to establish susceptibility and receptivity periods of host tissues and their relations to climatic conditions. The pathogen is able to survive as an epiphyte on leaves, buds and immature fruit. Its mode of spread has been studied. Chemical and biological disease control were evaluated and resuls show that disease control may be achieved by using an antagonistic strain of Bacillus subtilis or B. Amyloliquefaciens

Parkinson's disease (PD) is characterized by the progressive degeneration of substantia nigra (SN) dopaminergic neurons. Central players in PD pathogenesis, including mitochondrial dysfunction and oxidative stress, might affect the function of excitatory amino acid transporters (EAATs). Here, we investigated whether acute EAATs dysfunction might in turn contribute to the vicious cycles sustaining the progression of dopamine neuron degeneration. PDC application on nigral slices triggered sustained glutamate-mediated excitation selectively in dopamine neurons. In vivo time-course study (4-120 days) revealed that a single intranigral PDC injection triggers progressive degeneration of exclusively dopamine neurons with unilateral to bilateral and caudorostral evolution. This degenerative process associates GSH depletion and specific increase in γ-glutamyltranspeptidase activity, oxidative stress, excitotoxicity, autophagy and glial reaction. The anti-oxidant N-acetylcysteine and the NMDA receptor antagonists ifenprodil and memantine provided significant neuroprotection Transient compensatory changes in dopamine function markers in SN and striatum accompanied cell loss and axonal dystrophy. Motor abnormalities (hypolocomotion and forelimb akinesia) showed late onset, when ipsilateral neuronal loss exceeded 50%. These findings outline a functional link between EAATs dysfunction and several PD pathogenic mechanisms and pathological hallmarks, and provide the first acutely-triggered rodent model of progressive parkinsonism

In order to get a better understanding of brain complexity at a molecular level, we explored the mouse brain transcriptome using the Serial Analysis of Gene Expression method. SAGE libraries were generated from 11 mouse brain territories, including six cortical regions, striatum, accumbens nucleus, thalamus, substantia nigra and ventral tegmental area. The entire project delivered 1. 2 million SAGE tags, allowing the detection of rare mRNAs. Comparison of all transcriptomes revealed 308 transcripts differentially expressed, a number of which have no documented function. We further analyzed the expression profiles by real-time RT-PCR or in situ hybridization (ISH). Since the brain is a heterogeneous organ, it was important to determine the cell types that are expressing the novel markers. A combination of in situ hybridization with immunohistochemistry showed the expression of 3 midbrain-enriched mRNAs in dopaminergic neurons. We tested whether mouse markers could be human markers. There was a good overall conservation of expression patterns in both species. To evaluate the assumption that genes predominantly expressed in a given brain structure may indeed be relevant to its function, we chose pathophysiological conditions that target specific neuron populations. Using quantitative RT-PCR, we so far measured the abundance of striatum- or cortex-enriched transcripts in the mouse R6/2 genetic model of Huntington’s disease. Likewise, we showed the regulation of transcripts enriched in the striatum or substantia nigra in pharmacological rodent models of Parkinson’s disease, in which the nigro-striatal dopaminergic pathway has been lesioned

During my PhD, I precisely characterized the variations in electrical phenotype of the SNc DA neurons in Kv4.3 and SK3 KO animals, in physiological and pathophysiological conditions. In a first study, I analyzed a large number of electrophysiological parameters in these animals Combined with acute pharmacological blockade of these ion channels, I showed that Kv4.3 chronic deletion leads to a phenotypic change similar to the one induced by acute blockade of the channel while SK3 deletion appears to be compensated by other ion channels (in particular SK2). Motor behavior testing of Kv4.3 and SK3 KO animals confirmed the robustness of SK3 animals and the absence of robustness of Kv4.3 animals. In a second preliminary study, we used a bilateral partial lesion model to assess the behavioral and electrophysiological consequences of SK3 deletion on Parkinson's disease development. Our results suggest that in "Parkinson's" conditions, the chronic deletion of SK3 channel is associated with a slight anti-anxiety effect, the suppression of dopaminergic agonist hypersensitivity but also with motor deficits. From an electrophysiological viewpoint, the SNc DA neurons display a pacemaking behavior similar to the untreated condition. These two studies suggest that SNc DA neuron activity displays a partial and variable robustness to potassium channel deletion (robust to SK3 deletion, sensitive to Kv4.3 deletion) that can be revealed in physiological and pathophysiological conditions. This work will help understanding how ion channel mutations may alter SNc DA neuron vulnerability in Parkinson's disease

In disease suppressive soils, the rhizosphere microbial community protects plants from disease but only few microorganisms contributing to suppressiveness have been identified so far. The objective of the thesis was to characterize the rhizosphere bacterial community of soils suppressive to tobacco black root rot (caused by Thielaviopsis basicola) with a 16S taxonomic microarray (developed from previous prototypes). Microarray analysis of rhizobacterial communities from tobacco grown under greenhouse conditions revealed many differences in community composition between suppressive and conducive soil, indicating that black root rot suppressiveness may be brought about by the contribution of different plant-beneficial bacteria. In farmers’ fields, the rhizobacterial community was largely influenced by sampling year and plant species, however, a community pattern characteristic for suppressive soils could be identified despite varying field conditions. Based on these findings, Azospirillum, Herbaspirillum and Sphingomonadaceae were proposed as suppressiveness bioindicators in fields. Comparison of black root rot suppressive and conducive soils from different regions revealed that the rhizobacterial community was mainly determined by the region of origin, while suppressiveness was a less important factor. In conclusion, this work identified novel bacterial taxa that could serve as disease suppressiveness indicators, and it extends the range of bacterial taxa hypothesized to participate to black root rot suppression
