Ferraro, Benjamin James. "Examining the roles of CYCLOIDEA, RADIALIS and DIVARICATA in driving the evolution of flower shape Californian Diplacus pictus (Curran ex Greene) Nesom (Phrymaceae)." Thesis, California State University, Long Beach, 2014. http://pqdtopen.proquest.com/#viewpdf?dispub=1526903.
Повний текст джерелаFlower shape, color and size are extensively studied to both identify and classify different angiosperm taxa. The availability of well-supported molecular phylogenies produced using complex models of sequence evolution, coupled with an understanding of the genes that regulate morphological form in model organisms, and new methods to infer gene expression patterns in diverse species now allow us to understand the genetic basis of morphological differences among closely related species. Studies in Plantaginaceae, Gesneriaceae, Fabaceae and Brassicaceae show the importance of CYCLOIDEA (CYC), RADIALIS (RAD) and DIVARICATA (DIV) in regulating flower shape, but also show divergence in gene function within flowering plants. Previous studies in the zygomorphic model species Antirrhinum majus (snapdragon) have shown that AmCYC is expressed in the adaxial (dorsal) petals of flowers where it activates AmRAD . This expression of AmRAD within adaxial petals represses AmDIV expression causing AmDIV to be restricted to abaxial (ventral) and lateral petals. Like Antirrhinum , traditional Diplacus flowers have distinct dorsal, ventral and lateral petal identities. However, within the clade actinomorphic flowers have evolved independently on two occasions: once in D. pictus and once in D. mohaviensis. mRNA reveal DIV expression to be conserved between D. pictus and snapdragon, whereas CYC and RAD expression, and presumably function, differ between the two species. DpCYC is expressed in a narrow portion on the upper lip of abaxial petals, whereas DpRAD is expressed within both lateral and abaxial petals. D. pictus flowers are characterized by a novel upturned abaxial petal which may be linked to localized CYC expression along the upper surface of the structure. This study sheds new light on the mechanisms regulating flower shape in an endemic Californian monkey flower and shows the importance of testing hypotheses from model species such as Arabidopsis and snapdragon in non-model taxa such as D. pictus to undercover the true variety of mechanisms driving morphological evolution.
Sundström, Jens. "Evolution of genetic mechanisms regulating reproductive development in plants : Characterisation of MADS-box genes active during cone development in Norway spruce." Doctoral thesis, Uppsala University, Department of Evolutionary Biology, 2001. http://urn.kb.se/resolve?urn=urn:nbn:se:uu:diva-620.
Повний текст джерелаThe reproductive organs of conifers and angiosperms differ in morphology in several fundamental respects. The conifer Norway spruce (Picea abies) form pollen and seed cones from separate meristems whereas angiosperms bear bipartite flowers with sepals and petals surrounding two inner whorls of stamens and carpels. Despite these differences in morphology this thesis present data to suggest that reproductive development in conifers and angiosperms is regulated by a similar molecular mechanism. This implies an evolutionary conservation of the major mechanism for reproductive development since the origin of seed plants.
Flower organ identity in angiosperms is determined by regulatory genes belonging to the MADS-box gene family of transcription factors. This thesis presents the cloning and characterisation of four novel MADS-box genes from Norway spruce. Three of these genes DAL11, DAL12 and DAL13 are most closely related to angiosperm B function genes i.e. genes required for petal and stamen development. DAL11, 12 and 13 all are specifically active in developing pollen cones, with different temporal and spatial expression pattern. Functional analysis in transgenic Arabidopsis and yeast suggest that the reproductive aspect of the B-function is conserved between conifers and angiosperms. The results also suggest that the B-function in conifers is separated into one shoot identity and one organ identity determinant.
A fourth gene presented; DAL10, is specifically expressed in vegetative parts of pollen- and seed cones. Phylogenetically DAL10 is not closely related to any of the known angiosperm clades, but rather forms a separate clade with other gymnosperm genes, suggesting a gymnosperm specific function. We suggest that the DAL10 activity reflects a function in the determination of the reproductive shoot.

Повний текст джерелаA striking aspect of flowering plants is that, although they seem to display a great diversity of size and shape, they are made of the same basics constituents, that is the cells. The major challenge is then to understand how multicellular tissues, originally undifferentiated, can give rise to such complex shapes. We first investigated the uncharacterised signalling network of auxin since it is a major phytohormone involved in flower organogenesis.We started by determining the potential binary network, then applied model-based graph clustering methods relying on connectivity profiles. We demonstrated that it could be summarise in three groups, closely related to putative biological groups. The characterisation of the network function was made using ordinary differential equation modelling, which was later confirmed by experimental observations.In a second time, we modelled the influence of the protein dimerisation sequences on the auxin interactome structure using mixture of linear models for random graphs. This model lead us to conclude that these groups behave differently, depending on their dimerisation sequence similarities, and that each dimerisation domains might play different roles.Finally, we changed scale to represent the observed early stages of A. thaliana flower development as a spatio-temporal property graph. Using recent improvements in imaging techniques, we could extract 3D+t cellular features, and demonstrated the possibility of identifying and characterising cellular identity on this basis. In that respect, hierarchical clustering methods and hidden Markov tree have proven successful in grouping cell depending on their feature similarities

Повний текст джерелаGenome-wide efforts have identified a large number of long non-coding RNAs (lncRNAs), although their potential functions remain largely enigmatic. Here, we used a system for synchronized floral induction in Arabidopsis to identify 4106 flower-related long intergenic RNAs (lincRNAs). Flower-related lincRNAs are typically associated with functional enhancers which are bi-directionally transcribed and are associated with diverse functional gene modules related to floral organ development revealed by co-expression network analysis. The master regulatory transcription factors (TFs) APETALA1 (AP1) and SEPALLATA3 (SEP3) bind to lincRNA-associated enhancers. The binding of these TFs is correlated with the increase in lincRNA transcription and potentially promotes chromatin accessibility at enhancers, followed by activation of a subset of target genes. Furthermore, the evolutionary dynamics of lincRNAs in plants including non-flowering plants still remain to be elusive and the expression pattern in different plant species was quite unknown. Here, we identified thousands of lincRNAs in 26 plant species including non-flowering plants, and allow us to infer sequence conserved and synteny based homolog lincRNAs, and explore conserved characteristics of lincRNAs during plants evolution. Direct comparison of lincRNAs reveals most lincRNAs are species-specific and the expression pattern of lincRNAs suggests their high evolutionary gain and loss. Moreover, conserved lincRNAs show active regulation by transcriptional factors such as AP1 and SEP3. Conserved lincRNAs demonstrate conserved flower related functionality in both the Brassicaceae and grass family. The evolutionary landscape of lincRNAs in plants provide important insights into the conservation and functionality of lincRNAs.

Повний текст джерелаDos, Santos Carvalho Steve Francois. "Morpho-functional impact of Vangl2 on hippocampus development." Thesis, Bordeaux, 2016. http://www.theses.fr/2016BORD0276/document.
Повний текст джерелаPlanar Cell Polarity (PCP) is a signaling pathway originally known for its role in the establishment of cellular asymmetry perpendicular to the apico‐basal axis, in the plane of an epithelium. PCPsignaling has been shown to be crucial for many tissue patterning, including epithelial and mesenchymal tissue, but also cardiac, lung, bone, or kidney tissues, to cite a few. PCP signaling controls the regulation of cellular movement via the control of adhesion turnover and cytoskeleton reorganization. Vangl2 is one of the most upstream core PCP proteins that has been implicated in the recent years in various neuronal mechanisms, such as axonal guidance, dendrite morphogenesis or synaptogenesis. However, most of these studies rely on acute downregulation of the gene in vitro or in the use of a mouse presenting a spontaneous mutation of this gene, called Loop‐tail (Vangl2Lp) which causes the death of the embryo at birth. Moreover, the Vangl2Lp form of this protein has been described has a dominant‐negative form, making it difficult to untangle the molecular mechanism leading to the many phenotypes (included neuronal ones) reported inhomozygotes Looptail mice. To bypass this problem we created a conditional knockout (cKO) mouse in which vangl2 is deleted in the telencephalon during early embryogenesis. First, I analyzed the profile of expression of the protein during the first 3 weeks after birth, and I show that Vangl2 is specifically targeted to the arborization of granular cells (GC) of the dentate gyrus (DG) of the hippocampus, and excluded from cell bodies. Also, the protein was highly enriched in immature neurons of the subgranular zone of the DG, and in the stratum lucidum, a region of high‐density contacts between the GC and the CA3. In this region, a special type of synapse is formed: the Mossy Fiber Bouton (MfB) / Thorny Excrescence (TE) synapse. These synapses are bigger and more complex than conventional synapses. I then performed a structural and ultrastructural analysis of the DG/CA3 circuit in the Vangl2 cKO mice in order to understand the role of Vangl2 in the hippocampus maturation. For this, I used stereotaxic mice infection viruses, and Serial block face scanning electron microscopy (SBFsEM) with 3D reconstruction. Results show that in cKO mice, Mfs fasciculation is mildly impacted, and that the enlargement and complexification of the MfB/TE synapse is arrested, with TEs almost absent. I was able to link these morphological abnormalities to deficits in complex hippocampal‐dependent learning tasks. This work demonstrates for the first time the importance of PCP signaling for the in vivo maturation of a specific hippocampal circuit and its specific cognitive consequences. Next, I attempted to identify the functional consequences of vangl2 deletion on young hippocampal neuron maturation. My results confirm that Vangl2 is expressed in young hippocampal neurons and that the deletion of the gene affected neurite outgrowth on Ncadherin substrate. I used spt‐PALM‐TIRF super‐resolution microscopy to show that this increased neurite outgrowth was inversely proportional to a decrease in actin retrograde flowand to a decrease in the number of directed actin trajectories. These results strongly suggest that N‐cadherin adhesions are affected by Vangl2 deletion. FRAP experiments demonstratedthat in Vangl2 cKO neurons the recovery of N‐cadherin molecules engaged in homophilicbindings (adhesion) was decreased, suggesting that the turnover of N‐cadherin involved inadhesion is reduced. Altogether, I propose that Vangl2 controls the turnover/stability of Ncadherin proteins at adhesion sites to regulate local actin dynamics and consequently neuronal outgrowth

Повний текст джерелаThe digestive epithelium is covered with a protective mucus layer, regarded as a viscoelastic and permeable hydrogel. Mucins are large glycoproteins with a serine and threonine-rich protein backbone, linked to a wide variety of O-linked oligosaccharide side chains arranged in a bottle-brush configuration. Such O-glycans are nutritive sources for bacteria and/or potential ligands for bacterial adhesins, probably contributing in this way to the selection of the species-specific microbiota. In this thesis, we focused on unraveling multi-scale interactions between a vegetal L. lactis subsp. lactis isolate, TIL448 and a model mucin, Pig Gastric Mucin (PGM). Our study, based on the combination of different biophysical approaches and tools, has allowed dissecting the muco-adhesive and diffusive phenotype of L. lactis TIL448, in relation with the nature of the bacterial surface determinants and the structural, mechanical and rheological properties of the PGM network. Firstly, the muco-adhesion of TIL448 were examined using the single-cell scale AFM measurements with dedicated lacto-probes and shear stress flow chamber experiments at the bacterial population level, under laminar flow conditions. We also tested the plasmid-cured strain and two mutants, obtained by disruption of the genes encoding the major pilin and the mucus-binding protein. Then, the diffusion ability of L. lactis was determined by implementing a novel method, named Diffusion Front Tracking (DFT). It consists of tracking the diffusion front of stained cell suspensions over time within the PGM network. In a second part, in order to have a more thorough understanding of the L. lactis muco-adhesive and diffusive ability, the microstructure and mechanical properties of PGM were determined. Gel microstructure for varying PGM concentration was probed by the analysis of diffusivities of 200-nm and 500-nm fluorescent nanoparticles with different surface properties (carboxyl-terminated, amine-terminated and neutral charged tracers), using fluorescence Multiple-Particle Tracking

Повний текст джерелаDans un premier temps, nous avons déterminé le profil d’expression de XHRT1 au cours de l’embryogenèse. Nous avons observé que ce gène est fortement exprimé au stade neurula dans le plancher du tube neural, et que plus tardivement celui-ci est exprimé dans différentes régions du système nerveux, dans les somites et le dans le pronéphros. Comme attendu pour un membre de la famille des facteurs bHLH-O, nous avons également observé que l’expression précoce de HRT1 au niveau du plancher du tube neural est bien régulée par la voie de signalisation Notch.
Dans un deuxième temps, nous nous sommes intéressés au rôle et au mode d’action du facteur XHRT1 dans le développement du plancher du tube neural. Nous avons pu montrer que XHRT1 agit comme répresseur transcriptionnel et que cette répression nécessite la présence du domaine bHLH et de séquences en aval de celui-ci. Nous avons montré en embryon que la surexpression précoce de XHRT1 induit un blocage de l’expression des marqueurs du mésoderme et une augmentation de marqueur du plancher du tube neural, ce qui est en accord avec le modèle selon lequel la voie de signalisation Notch interviendrait dans le choix de la destinée des cellules de la région médiane en inhibant la différenciation des cellules en notocorde et en favorisant leur différenciation en cellules du plancher du tube neural. XHRT1 n’étant cependant activé qu’à partir du stade neurula, nous avons conclu que les effets observés n’étaient probablement pas dus à XHRT1 mais à un autre facteur bHLH-O apparenté exprimé plus précocement dans les cellules de la ligne mediane de l’embryon. Afin d’éviter ces effets non spécifiques précoces, nous avons utilisé un vecteur d’expression de XHRT1 permettant un contrôle temporel de l’activité de la protéine. Nous avons ainsi montré que l’activation de XHRT1 au stade neurula dans l’ectoderme inhibe la différenciation des cellules précurseurs neurales en neurones et qu’il pourrait ainsi jouer un rôle important dans le développement du plancher du tube neural. Nos résultats ont montré également que XHRT1 est capable d’homo- et hétérodimériser in vivo avec les facteurs Xhairy1 et Xhairy2b coexprimés avec XHRT1 dans le plancher du tube neural. Enfin, nous avons montré que les propriétés de dimérisation de XHRT1 sont dépendantes non seulement du domaine bHLH, mais aussi du domaine Orange et des séquences situées en aval, séquences jouant un rôle important dans le choix du partenaire.
Des travaux récents ayant montré que la voie de signalisation Notch joue un rôle important dans le développement du rein, nous avons voulu déterminer l’importance de XHRT1 dans le développement du pronéphros. Nos résultats ont montré que XHRT1 ainsi que d’autres facteurs bHLH-O sont exprimés de manière dynamique, d’abord dans le glomus puis dans la partie dorso-antérieure de l’ébauche du pronéphros à l’origine des tubules proximaux, et que leur expression est régulée positivement par Notch. La surexpression de XHRT1 à la fin de la neurulation inhibe la formation du canal et du tubule distal, tandis que l’inhibition de la traduction de la protéine entraîne une réduction de l’expression de marqueurs spécifiques des tubules proximaux et du glomus. Ces résultats démontrent que XHRT1 joue un rôle important comme médiateur de la voie de signalisation Notch dans le pronéphros.

Повний текст джерелаDuring my PhD we showed, by the alteration of proline biosynthetic gene P5CS1, that the modulation of proline affects, in Arabidopsis plants, the flower transition and axillary bud proliferation. Morover we investigated the role and the relative contribution in flowering and development of P5CS2, a gene homolog to P5CS1 and we discovered a non redundant role of these two genes in embryo development while a their redundant role in flower transition. In the last year of my PhD thesis we are investigated the floral pathway proline is involved in. Preliminary data, from relative and quantitative RT-PCR, revealed a significative upregulation of the floral integrator gene FLC, strongly suggesting that proline interacts with the autonomous pathway.
Di, Pietro Rebecca. "Development of a protocol with concentrated bacteria for fecal microbiota transplantation and impact on the equine fecal microbiota after antibiotic-induced dysbiosis." Thesis, 2020. http://hdl.handle.net/1866/24704.
Повний текст джерелаThe equine gut microbiota plays an important role in maintaining the health of the host. The gut microbiota is composed of many microorganisms such as bacteria, viruses, fungi, and archaea. However, the majority of these microbial cells are bacterial cells, and consequently, many studies, including the present one, focus on exploring bacterial communities in the gut. An imbalance of the gut microbiota, termed dysbiosis, has been observed in several conditions such as colitis, colic, after antibiotic administration, or diet modification. Restoration of the gut to a healthy state can be performed through fecal microbiota transplantation (FMT). Studies using current recommendations for FMT have shown clinical recovery in horses with diarrhea, but the microbiota remains largely unchanged after FMT and no controlled studies have been performed. The hypotheses of this project were that treatment with concentrated FMT will correct dysbiosis faster than conventional FMT and the vehicle, and that the gut microbiota of horses treated with concentrated FMT will resemble the gut microbiota of the donor. The objective of this project was to develop an improved protocol for FMT in horses, by increasing the concentration of bacteria found in the donor stool using centrifugation, and to test it in horses with antibiotic-induced intestinal dysbiosis. The antibiotic trimethoprim sulfadiazine (TMS) was administered to nine horses to induce intestinal dysbiosis. Horses were separated into three groups: horses receiving concentrated FMT (cFMT) (n=3); horses receiving fresh FMT (fFMT), as per current recommendations (n=3); horses receiving a vehicle (VEH) with 10% glycerol in 0.9% saline (n=3). Fecal samples were collected before and after antibiotic administration, as well as before, during, and after transplantation. Sequencing was performed using the Illumina MiSeq platform and data analysed using the software Mothur. As expected, the antibiotic TMS significantly decreased the richness in all horses (P < 0.05). Unexpectedly, the membership of the cFMT and fFMT donor fecal suspensions was significantly different from cFMT and fFMT recipients’ baseline membership, respectively. The membership of the cFMT and fFMT recipient horses was significantly different after transplantation, while the vehicle recipients were not. In addition, the Escherichia genus was found in significantly higher relative abundances in the cFMT donor fecal suspensions when compared to the fFMT donor fecal suspensions. The main limitations of this study are the small sample size and exposure of cFMT donor stool to oxygen and freeze-thawing. In addition, the dysbiosis model may not be optimal to test the efficacy of FMT, and studies performing FMT in horses with diarrhea are warranted. This study contributed to the search for novel approaches to improve FMT in horses. The weak effect of both FMT protocols on the gut microbiota and the increase in Escherichia suggest that further clinical studies are needed before FMT can be recommended to treat and prevent dysbiosis in horses.
