Albert, Elise. "Déterminants génétiques et génomiques de la réponse au déficit hydrique chez la tomate (Solanum lycopersicum) et impact sur la qualité des fruits." Thesis, Avignon, 2017. http://www.theses.fr/2017AVIG0688/document.
Full textWater scarcity will constitute a crucial constraint for agricultural productivity in a nearfuture. High throughput approaches in model species have identified hundreds of genespotentially involved in survival under drought conditions, but very few having beneficialeffects on quality and yield in crops plants. Nonetheless, controlled water deficits mayimprove fleshy fruit quality through weaker dilution and/or accumulation of nutritionalcompounds. In this context, the first part of the PhD was aimed at deciphering the geneticdeterminants of the phenotypic response to water deficit in tomato by exploring thegenotype by watering regime (G x W) and QTL by watering regime (QTL x W) interactions intwo populations. The first population consisted in recombinant inbreed lines (RIL) from across between two cultivated accessions and the second was composed of diverse small fruittomato accessions mostly native from South America. Plants were phenotyped for majorplant and fruit quality traits and genotyped for thousands of SNP. Data were analyzed withinthe linkage and association mapping frameworks allowing the identification of QTLs andputative candidate genes for response to water deficit in tomato. The second part of the PhDhad the objective to explore gene regulation in green fruit and leaves of tomato plantsstressed by water deficit. For this purpose, RNA-Seq data were collected on the two parentalgenotypes of the RIL population and their F1 hybrid. Data were analyzed to identifydifferentially expressed genes and allele specific expression (ASE). Then, the expression of200 genes was measured in leaves and fruits of the whole RIL population by high throughputmicrofluidic qPCR. eQTLs and eQTL by watering regime interactions were mapped for thosegenes using linkage mapping. Colocalisations with the phenotypic QTLs were analyzed. Theknowledge produced during this PhD will contribute to a better understanding of the tomatoplant interaction with their environment and provide bases for improvement of fruit qualityunder limited water supply
Jha, Ankita. "Quantitative control of GPCR organization and signaling by endocytosis in epithelial morphogenesis." Thesis, Aix-Marseille, 2017. http://www.theses.fr/2017AIXM0393/document.
Full textDuring Drosophila gastrulation, apical activation of the actomyosin networks drives apical constriction in the invaginating mesoderm and cell-cell intercalation in the extending ectoderm. Here, we show that cell-surface G-protein coupled receptor, Smog activates G-proteins, Rho1 and Rho-kinase that is required for apical constriction and cell-cell intercalation. Quantitative control over GPCR activity and thereby Rho1 activation underlies differences in deformation of the mesoderm and ectoderm cells but the mechanisms remain elusive. We show that GPCR-Smog activity is concentrated on two different apical plasma membrane compartments i.e. the surface and the plasma membrane invaginations. Using FCS, we probe the surface of the plasma membrane (PM) and show that Smog homo-clusters in response to its activating ligand Fog. Endocytosis of Smog is facilitated by the kinase Gprk2 and the adaptor protein β-Arrestin-2 that clears active Smog from the surface of PM. When Fog concentration is high or endocytosis is low, Smog arranges in homo-clusters and accumulates in plasma membrane invaginations (PMI), that are hubs for Rho1 activation. Lastly, we find high Smog homo-cluster concentrations and numerous apical PMIs in the mesoderm compared to the ectoderm. We identify that dynamic partitioning of active Smog on the surface of the PM or PMI directly impact on Rho1 signaling. PMIs accumulate high Rho1-GTP suggesting they form signaling centers. Fog concentration and Smog endocytosis form coupled regulatory processes that regulate quantitative differential Rho1/MyoII activation in the Drosophila mesoderm and ectoderm

Full textThe thesis is organized in three research papers. The paper of the first chapter is: “Quantitative Easing and Excess Reserves”. The chapter 2 offers a paper named: “New Evidence on the Effects of Quantitative Easing”. The chapter 3 is a paper called: “State-contingent Forward Guidance”.“Quantitative Easing and Excess Reserves”: What are the impacts of a flush of interest-bearing excess reserves to the real economy? Surprisingly, the theoretical literature remains silent about this ques- tion. We address this issue in a newKeynesian model with various financial frictions and reserve requirements in the balance sheet of bankers. Modeling QE by the supply of excess reserves allows for endogenous changes in the relative supply of financial assets. We find that this mechanism is crucial to identify and disentangle between the portfolio balance, the credit and the asset prices channels of QE. Further, we demonstrate that the macroeconomic effects of QE are rather weak and mainly transmitted through the asset prices channel.“New Evidence on the Effects of Quantitative Easing”: Have the macroeconomic effects of QE programs been empirically overestimated? Using a large set of model specifications that differ in the degree of time-variation in parameters, the answer is yes. Our forecasting exercise suggests that it is crucial to allow for time-variation in parameters, but not for stochastic volatility. In an analysis of structural QE shocks, we find that QE1 had larger macroeconomic effects than QE2 and QE3, but much smaller than usually found in the literature.“State-contingent Forward Guidance”: In this paper, the impacts of a statecontingent forward guidance are assessed in a DSGE model with search and matching frictions. Under an Odyssean perspective, the commitment is found to have relatively low effects in the economy. This result tackles the so-called forward guidance puzzle. In addition, the simulations suggest that a statecontingent forward guidance is mainly transmitted by shifts in the expectations of inflation

Full textFrench dairy goats recently integrated genomics with the development of a DNA chip in the 2010s and the first QTL detections and genomic evaluations. The availability of sequence data for farm animals opens up new opportunities. The VarGoats project is an international 1,000 genomes resequencing program designed to provide sequence information of the Capra hircus species. The study of imputation quality to sequence level is a necessary first step before using imputed sequences in association analysis and genomic evaluations. The main objective of this work was to study the possible integration of sequence data in the French dairy goats breeding programs. The set up of a quality check represented a sizable part of this thesis. It was based on bibliographic research and the comparison between available 50k genotypes and sequence data. Out of the initial 97,889,899 SNPs and 12,304,043 indels, we eventually retained 23,338,436 variants including 40,491 SNPs of the Illumina GoatSNP50 BeadChip. A preliminary study of imputation from 50k genotypes to sequence was then performed with the aim of getting a sufficient number of sequenced animals of good quality. Several softwares and methods were considered (family or population imputation) using the 829 sequenced animals available. Within-breed imputation led to genotype and allele concordance of 0.74 and 0.86 in Saanen and 0.76 and 0.87 in Alpine respectively. Correlations were then of 0.26 and 0.24 in Alpine and Saanen respectively. Imputed sequence of males confirmed signals previously identified using 50k genotypes and allowed the detection of new regions of interest. The density of sequence data represented an unprecedented opportunity to deepen our understanding of QTL region of chromosome 19 in the Saanen breed. This region is associated to production, type and udder health traits as well as semen production traits. Our analysis did not point out any candidate mutation. However, we offer a simple way to identify genomic and phenotypic profiles in the Saanen breed using 50k genotypes. This method could be of use for early prediction in France but also worldwide. Finally, using all previous results, we studied the impact of the integrating imputed sequence data of chromosome 19 on the accuracy of evaluations in French Saanen. Several evaluation models were compared : single-step GBLUP (ssGBLUP) and weighted single-step GBLUP (WssGBLUP) using different panels of imputed variants. Best results were obtained using ssGBLUP with 50k genotypes and all variants on the QTL region of chromosome 19 (between 24.72 and 28.38Mb): +6.2% accuracy on average for all evaluated traits. The 50k chip update to which I participated represents a opportunity to improve genomic evaluations. Indeed, it significantly improved accuracy of predictions (between 3.1 and 6.4% on average depending on the scenario) while limiting computation time associated to imputation. This work confirms the benefits of using sequence data in the French dairy goats breeding programs and opens up the perspective of integrating them in the routine genomic evaluations

Full textSince November 2008, the Federal Reserve of the United States pursued a series of large-scale asset purchases, known as Quantitative Easing. In this Work Project, I describe the context, the objectives and the implementation of the Quantitative Easing. Additionally, I discuss its expected effects. Finally, I present empirical evidence of the effects on interest rates, output and inflation. I conclude that the first round of purchases was effective on preventing deflation and depression while the second had a small impact on economy.

Full textIn this work, new concepts for the calibration free analysis by laser induced breakdown spectroscopy (LIBS) and for plasma diagnostics on laser induced plasma have been developed. In the course of this, already known techniques were analyzed for weaknesses and limitations. New techniques, based these findings, were presented. Using computer simulations of perfectly defined and entirely modifiable plasmas, the well known CF-LIBS (calibration free LIBS) technique was evaluated. The influence of all plasma parameters on the analysis result was investigated. It was shown that this technique, in its current form, is capable to deliver semi quantitative results only. An improvement of CF-LIBS was achieved by the use of spatially resolved measurements, overcoming the plasma heterogeneity. Combination of this approach with plasma simulation to find the parameters temperature and density, both important factors in calibration free analytics, much more stable results could be obtained. However, the well known technique for spatially resolved plasma investigation, the Abel Inversion, is limited to cylindrically symmetric plasmas only. Even weak disturbances of such symmetry can lead to major errors in the results. Using the inverse Radon Transformation, which is being introduced to plasma diagnostics on laser induced plasma by the present work, the first close to reality reconstructions and investigations of plasma with disturbed symmetry and even intrinsic asymmetry were conducted. This opens a new field in plasma diagnostics and helps to a better understanding of laser induced plasmas in general. It forms the foundation of further development of laser induced breakdown spectroscopy to become an absolute method.

"Quantitative analysis of the regulation of the DNA replication program by the intra-S phase checkpoint in Xenopus embryos Checkpoint control of the spatio-temporal regulation of DNA replication in Xenopus early embryos Polo-like kinase 1 (Plk1) is a positive regulator of DNA replication in the Xenopus in vitro system On the Interplay of the DNA Replication Program and the Intra-S Phase Checkpoint Pathway Genome wide decrease of DNA replication eye density at the midblastula transition of Xenopus laevis Polo like kinase 1 promotes dispersed replication origin firing during S phase." Thesis, Université Paris-Saclay (ComUE), 2019. http://www.theses.fr/2019SACLS478.
Full textThe initiation of DNA replication in multicellular organisms starts from several thousand genomic loci called replication origins. They are grouped into domains which replicate early or late during S phase. The firing of a replication origin creates two diverging replication forks that replicate flanking DNA. One of the mechanisms regulating DNA replication program is the ATR/Chk1 dependent intra-S phase checkpoint. This pathway is activated by replicative stress due to stalled replication forks at early firing origins and in turn, inhibits the late firing of origins. It has been proposed that the checkpoint recovery kinase Plk1 (Polo-Like-Kinase 1) could be responsible for allowing origin firing close to stalled forks in replication stress conditions. However, origin firing has not been analysed after Plk1 inhibition or depletion during unperturbed S phase. To assemble a comprehensive and unified view of the DNA replication process numerical and analytical models have been built in the past, but none of them integrates the role of checkpoint pathways. The goal of my thesis was to investigate experimentally and analytically how the checkpoint regulates the firing of origins in space and time and, in particular, whether the Plk1 is implicated in the regulation of origin firing during unperturbed S phase. To this end, I used the Xenopus in vitro system. First, I integrated in a numerical model the checkpoint pathway to describe the replication program in the Xenopus in vitro system. I tested different scenarios and used DNA combing data previously obtained by the laboratory after the inhibition of the checkpoint kinase Chk1. Monte Carlo simulated data were fitted to experimental data by optimizing the values of free parameters of models using a genetic algorithm. I found that two new hypothesis should be added to formerly built replication models: 1) a strong inhibition of origin firing by Chk1 from the beginning of S phase 2) the presence of early replicating genomic domains that evade the origin firing inhibition. Second, I experimentally showed that during unperturbed S phase active Plk1 is recruited to chromatin before the start of S phase and that in the absence of Plk1, DNA replication is slowed down. Moreover, Plk1 depletion led to an increase in Chk1 phosphorylation (p-Chk1) and a decrease of Cdk2 activity, suggesting that Plk1 inhibits the intra-S phase checkpoint. Performing DNA combing, I demonstrated that Plk1 depletion leads to a decrease in origin firing level. Analysis of the combing data by the developed numerical model suggested that during unchallenged S phase Plk1 down regulates the global origin firing inhibitory action of Chk1, consistent with the experimental observation of increased level of p-Chk1 in Plk1 depleted Xenopus egg extract. However, Plk1 does not seem to act close to replication forks as was proposed earlier. Finally, by considering replication process as a one-dimensional nucleation and growth process and using statistical methods, I developed a new quantitative approach to study the regulation of replication program. This approach links the similarity between single molecule replication patterns to DNA replication regulating processes. By analyzing DNA combing data, I showed that DNA replication program in Xenopus early embryos is regulated by two spatially and temporally exclusive processes. One with low frequency of origin firing and high apparent fork speed and a second, controlled by PlK1, with a high frequency of origin firing and a low apparent fork speed. Altogether my results demonstrate that Plk1 positively regulates replication origin firing during normal S phase by down regulating the replication checkpoint. The numerical model predicts the existence of replication timing domains in the Xenopus model system. Future work will show whether Plk1 regulates the replication program at the level of genomic domains

We mapped 8 QTL implicated in testis, development, prostate growth, sperm vitality and morphology. We performed fine mapping analysis of a QTL of reduced testis weight associated with teratozoospermia, localised on MMU11. We proposed a candidate locus encompassing four testis expressed gene. Moreover, in order to understand gene expression regulation in interspecific mosaic genome, we analysed testis transcriptome of three IRC strains compared with parental strains testis transcriptome. In this study, we describe how spretus genes are regulated when introgressed in musculus background. This study gives some insight concerning gene flow tolerance across the specie barrier during emergence of mosaic genome

Full textThis thesis deals with quantitative stochastic homogenization of parabolic partial differential equations, and discrete elliptic problems. In the introduction, we see how can such problems come from random models, even when the coefficients are deterministic. Then, we introduce homogenization : what happen if the coefficients themselves are random ? Could we consider that an environment with microscopical random heterogeneities behaves, at big scale, as a fictious deterministic homogeneous environment ? Then, we give a random walk in random environment interpretation and the sketch of the proofs in the two following chapters. In chapter II, we prove a quantitative homogenization result for parabolic PDEs, such as heat equation, in environment admitting time and space dependent coefficients. The method of the proof consists in considering solutions of such problems as minimizers of variational problems. The first step is to express solutions as minimizers, and then to use the capital property of subadditivity of the corresponding quantities, in order to deduce convergence and concentration result. From that, we deduce a rate of convergence of the actual solutions to the homogenized solution. In chapter III, we adapt these methods to a discrete elliptic problem on the lattice Zd

Full textThis thesis contributes to the theoretical study and application of quantitative verification and synthesis. We first study strategies that optimize the ratio of two rewards in MDPs. The goal is the synthesis of efficient controllers in probabilistic environments. We prove that deterministic and memoryless strategies are sufficient. Based on these results we suggest 3 algorithms to treat explicitly encoded models. Our evaluation of these algorithms shows that one of these is clearly faster than the others. To extend its scope, we propose and implement a symbolic variant based on binary decision diagrams, and show that it cope with millions of states. Second, we study the problem of program repair from a quantitative perspective. This leads to a reformulation of program repair with the requirement that only faulty runs of the program be changed. We study the limitations of this approach and show how we can relax the new requirement. We devise and implement an algorithm to automatically find repairs, and show that it improves the changes made to programs.Third, we study a novel approach to a quantitative verification and synthesis framework. In this, verification and synthesis work in tandem to analyze the quality of a controller with respect to, e.g., robustness against modeling errors. We also include the possibility to approximate the Pareto curve that emerges from combining the model with multiple rewards. This allows us to both study the trade-offs inherent in the system and choose a configuration to our liking. We apply our framework to several case studies. The major case study is concerned with the currently proposed next generation airborne collision avoidance system (ACAS X). We use our framework to help analyze the design space of the system and to validate the controller as currently under investigation by the FAA. In particular, we contribute analysis via PCTL and stochastic model checking to add to the confidence in the controller

Full textThe first chapter shows how interbank market fragmentation disrupts the transmission of monetary policy. Fragmentation is the fact that banks, depending on their country of location,have different probabilities of default on their interbank borrowings. Once fragmentation is introduced into standard theoretical models of monetary policy implementation, excess liquidity arises endogenously. This leads short-term interest rates to depart from the central bank policy rates. Using data on cross-border financial flows and monetary policy operations,it is shown that this mechanism has been at work in the Euro-Area since 2008. The model is used to analyze conventional and unconventional monetary policy measures. The second chapter shows how the Euro area money market rates have been standing below the deposit facility rate since 2015, which financial markets perceive as a byproduct of Eurosystem's public sector purchase program (PSPP). This paper explores empirically the interactions between the PSPP and short term secured money market rates (repo rates). We document different channels through which asset purchases may affect the various segments of the Euro area repo market. Using proprietary data from the PSPP and individual repo transactions made on the repo market for specific securities, our results show that the PSPP has contributed to push down repo rates. Purchasing 1% of a bond outstanding is associated with a decline in its repo rate of -0.75 bps

Full textTiivistelmä Nivelrikko on erittäin yleinen nivelten rappeumasairaus, joka aiheuttaa kipua, jäykkyyttä sekä liikkumisvaikeutta. Nivelrikon nykyistä varhaisempi diagnosointi olisi äärimmäisen tärkeää, jotta voitaisiin vähentää oireiden esiintymistä ja hidastaa sairauden etenemistä. Ultraäänikuvaus on lupaava menetelmä nivelrikon varhaisdiagnostiikkaan, mutta sitä ei kuitenkaan ole vielä yleisesti hyväksytty rutiininomaiseen kliiniseen käyttöön. Tämän tutkimuksen päätavoitteena oli selvittää polven semi-kvantitatiivisen ultraäänikuvauksen diagnostista kykyä verrattuna perinteiseen röntgenkuvaukseen, kun arvioidaan rustokudoksen kulumista, luupiikkejä sekä nivelkierukan siirtymää. Magneettikuvausta käytettiin vertailumenetelmänä. Toisena tavoitteena oli selvittää yhteyttä polven ultraäänilöydösten ja polven kivun sekä liikkuvuuden välillä. Lopuksi selvitettiin, voidaanko kvantitatiivisella analyysilla parantaa ultraäänikuvauksen tarkkuutta varhaisvaiheen nivelrikkopotilaiden rustonalaisen luun kunnon määrittämiseen. Röntgenkuvaukseen verrattuna ultraäänikuvaus osoittautui vähintään yhtä hyväksi tai paremmaksi kuvantamismenetelmäksi, kun arvioitiin reisi- ja sääriluun luupiikkejä, sisemmän nivelkierukan siirtymää tai rustokudoksen kulumista. Reisiluun nivelruston yleinen kulumisen aste oli suoraan verrannollinen potilaiden polvinivelen liikerajoituksiin ja kipuun. Erityisesti reisiluun sisemmän puolen nivelruston kuluminen sekä ulomman puolen luupiikit liittyivät potilaiden oireisiin. Kvantitatiiviset ultraäänitulokset osoittivat, että ultraäänen rusto-luurajapinnalta tulevan heijastuksen maksimi-intensiteetti lisääntyi sekä intensiteetin tason laskunopeus vähentyi nivelrikon vaikeusasteen kasvaessa. Tutkimus osoitti, että ultraäänikuvauksella voidaan saada tärkeää diagnostista lisätietoa polven nivelrikon aiheuttamista kudosmuutoksista, joita ei pystytä havaitsemaan perinteisellä röntgenkuvauksella. Ultraäänikuvauksessa näkyvät kudosmuutokset liittyvät myös potilaan kliinisiin oireisiin. Lisäksi rustonalaista luuta voidaan analysoida kvantitatiivisesti ultraäänikuvien perusteella, mikä edelleen helpottaa kuvien tulkintaa. Tutkimuksen perusteella voidaankin suositella ultraäänikuvauksen nykyistä laajempaa kliinistä käyttöä röntgenkuvausta täydentävänä tutkimusmenetelmänä nivelrikon varhaisdiagnostiikassa
