Abstract Arbuscular mycorrhizal fungi (AMF) form symbiosis with roots of approximately 80% of known land plants. These fungi play a key role in the ecology and adaptation of plants to various ecosystems.by increasing the plant resources for various nutrients. Despite their important ecological role, we still have poor understanding of their genetic structure and their molecular evolution. The work presented in this thesis aims to isolate and analyse AMF genes with various molecular techniques, in order to obtain new insights about their genetics, phylogeny and molecular evolution. Some AMF genes were shown through phylogenetic analyses to be more related with plants or mycoparasites than with other fungal organisms. These results led to the prediction that lateral gene transfers (LGT) occurred between AMF and plants during their long-term co-évolution. By phylogenetic and molecular analyses, in the chapter 2 I demonstrate that the hypothesis of LGT is most likely a consequence of analyses carried out on contaminant non AMF-DNA. In addition, various features characteristic of AMF genes have been determined, allowing researchers to scan their own sequence databases for potential non-AMF contaminants. Phylogenetic relationships of AMF with other fungi has been mostly analysed using molecular markers of ribosomal origin. In chapter 2 I successfully isolated gene encoding α- and ß-tubulins from several AMF genera. Consequently, phylogenetic analyses showed that AMF possess an unexpected relationship with ancestral aquatic fungi (chytrids). These results are consistent with the prediction stating that AMF may have played an important role in the colonisation of land by green plants through the establishment of a symbiosis and after the divergence of AMF from aquatic ancestors. In Chapter 4 I tried to isolate the entire AMF gene family encoding P-Type II ATPases, in order to determine their molecular evolution with the fungal kingdom. These genes were further analysed to detect the level of sequence polymorphism that is present within an AMF population. The results obtained show that mutational events previously thought as occurring only among divergent evolutionary lineages (gene duplications, indel mutations in coding regions) can occur within a single population of AMF. These results have far reaching consequences for our understanding of the genetics and ecology of AMF. Résumé Les champignons endomycorrhiziens arbusculaires (CEA) forment une symbiose racinaire avec environ 80% des plantes vasculaires connues. Ces champignons possèdent un rôle important dans l'écologie et l'adaptation des plantes au sein de différents écosystèmes en .augmentant leurs ressources en nutriments. Le travail présenté dans cette thèse se propose d'isoler et d'analyser certains gènes de CEA avec différentes techniques moléculaires à fin d'obtenir de pÌus amples informations concernant l'évolution moléculaire, la phylogénie et leur diversité génétique à diverses échelles taxonomiques. Certaines analyses phylogénétiques des CEA ont conduit à l'hypothèse que des transferts horizontaux de gènes (THG) ont pu avoir lieu durant leur longue co-évolution avec les plantes vasculaires. Dans le chapitre 2 de cette thèse nous démontrons par analyses moléculaire et phylogénétique que l'hypothèse de THG est une conséquence de contaminations à partir d'ADN de plante ou d'autres micro-organismes. De plus, de nombreuses caractéristiques moléculaires de CEA ont pu être déterminées, permettant la mise en place d'un plan à suivre lors de l'analyse de gènes de CEA dans les études futures. Les relations évolutives des. CEA avec d'autres champignons ont été analysées majoritairement à l'aide de marqueurs moléculaires d'origine ribosomiale. Dans les chapitres 2 et 3 j'ai isolé des gènes codant pour l'a- et la ß-tubuline chez différents genres, de CEA. Les analyses phylogénétiques ont démontré une parenté entre les CEA et des champignons aquatiques ancestraux (chytrides). Ces résultats sont en accord avec l'hypothèse selon laquelle les CEA ont probablement joué un rôle primordial dans l'établissement des plantes sur terre à travers une symbiose et suite à leur évolution à partir d'ancêtres vivant dans des milieux aquatiques: Dans le chapitre 4 j'ai isolé une entière famille de gènes chez les CEA codant des ATPases de la membrane plasmique, et étudié leur évolution moléculaire dans le règne des champignons. Ces mêmes gènes ont été analysés ultérieurement à fin de déterminer le degré de polymorphisme de séquence qui peut être présent au sein d'une population de CEA. Les résultats obtenus montrent que des évènements mutationnels considérés comme apparaissant exclusivement dans des lignées évolutives très divergentes (duplication de gènes, insertions/délétions dans des régions transcrites du génome) ont lieu sein d'une même population de CEA. Cette découverte a un impact important sur nos connaissances concernant la génétique des populations des CEA et leur écologie.

The Spanish judicial system is independent and headed by the Supreme Court. Spain has a civil law system. The criminal procedure is governed by the legality principle--by opposition to the opportunity or expediency principle--which implies that prosecution must take place in all cases in which sufficient evidence exists of guilt. Traditionally, the role of the PPS in Spain has been very limited during the investigative stage of the process. That stage is under the responsibility of the Examining Magistrate (EM). Since the end of the 1980s, a series of modifications has been introduced in order to extend the functions of the PPS. In 1988, the PPS received extended competences which allow them to receive reports of offenses. Upon knowing of an offense (reported or known to have been committed), the PPS can initiate the criminal proceeding. The PPS is also allowed to lead a sort of plea bargain under a series of restrictive conditions and only for some offenses. At the same time, the PPS received extended competences in the juvenile justice criminal proceeding in 2000. With all this said, the role of the PPS has not changed radically and, during the investigative stage of the process, their main role remains the presentation of the accusation, playing a more active role during the trial stage of the proceeding. In this article the national criminal justice system of Spain is described. Special attention is paid to the function of the PPS within this framework and its relationship to police and courts. The article refers to legal provisions and the factual handling of criminal cases.

This paper proposes a detailed measurement of the agricultural development of the island of Majorca from the late sixteenth century to the midnineteenth century, with an emphasis on the products which made up the bulk of the island’s agricultural production. The authors have organized most of the existing databases in the island’s archives and have also incorporated quantitative and qualitative material from their own research and that of other colleagues. Due to their quality and regularity, the data are among the richest known for pre-industrial Europe. These sources lead to some conclusions which link with recent debates in European economic history concerning the calculation of economic growth in economies for periods before statistics were kept. The text presents a methodological analysis covering almost 80 per cent of agricultural production of the island of Majorca and leaves conclusions to be supplemented by further studies of the manufacturing and service sectors

Background: The variety of DNA microarray formats and datasets presently available offers an unprecedented opportunity to perform insightful comparisons of heterogeneous data. Cross-species studies, in particular, have the power of identifying conserved, functionally important molecular processes. Validation of discoveries can now often be performed in readily available public data which frequently requires cross-platform studies.Cross-platform and cross-species analyses require matching probes on different microarray formats. This can be achieved using the information in microarray annotations and additional molecular biology databases, such as orthology databases. Although annotations and other biological information are stored using modern database models ( e. g. relational), they are very often distributed and shared as tables in text files, i.e. flat file databases. This common flat database format thus provides a simple and robust solution to flexibly integrate various sources of information and a basis for the combined analysis of heterogeneous gene expression profiles.Results: We provide annotationTools, a Bioconductor-compliant R package to annotate microarray experiments and integrate heterogeneous gene expression profiles using annotation and other molecular biology information available as flat file databases. First, annotationTools contains a specialized set of functions for mining this widely used database format in a systematic manner. It thus offers a straightforward solution for annotating microarray experiments. Second, building on these basic functions and relying on the combination of information from several databases, it provides tools to easily perform cross-species analyses of gene expression data.Here, we present two example applications of annotationTools that are of direct relevance for the analysis of heterogeneous gene expression profiles, namely a cross-platform mapping of probes and a cross-species mapping of orthologous probes using different orthology databases. We also show how to perform an explorative comparison of disease-related transcriptional changes in human patients and in a genetic mouse model.Conclusion: The R package annotationTools provides a simple solution to handle microarray annotation and orthology tables, as well as other flat molecular biology databases. Thereby, it allows easy integration and analysis of heterogeneous microarray experiments across different technological platforms or species.

BACKGROUND: Control of blood pressure (BP) remains a major challenge in primary care. Innovative interventions to improve BP control are therefore needed. By updating and combining data from 2 previous systematic reviews, we assess the effect of pharmacist interventions on BP and identify potential determinants of heterogeneity. METHODS AND RESULTS: Randomized controlled trials (RCTs) assessing the effect of pharmacist interventions on BP among outpatients with or without diabetes were identified from MEDLINE, EMBASE, CINAHL, and CENTRAL databases. Weighted mean differences in BP were estimated using random effect models. Prediction intervals (PI) were computed to better express uncertainties in the effect estimates. Thirty-nine RCTs were included with 14 224 patients. Pharmacist interventions mainly included patient education, feedback to physician, and medication management. Compared with usual care, pharmacist interventions showed greater reduction in systolic BP (-7.6 mm Hg, 95% CI: -9.0 to -6.3; I(2)=67%) and diastolic BP (-3.9 mm Hg, 95% CI: -5.1 to -2.8; I(2)=83%). The 95% PI ranged from -13.9 to -1.4 mm Hg for systolic BP and from -9.9 to +2.0 mm Hg for diastolic BP. The effect tended to be larger if the intervention was led by the pharmacist and was done at least monthly. CONCLUSIONS: Pharmacist interventions - alone or in collaboration with other healthcare professionals - improved BP management. Nevertheless, pharmacist interventions had differential effects on BP, from very large to modest or no effect; and determinants of heterogeneity could not be identified. Determining the most efficient, cost-effective, and least time-consuming intervention should be addressed with further research.
