Abstract:
Satellite RNAs and satellite viruses are extraviral components that can affect either the pathogenicity, the accumulation, or both of their associated viruses while themselves being dependent on the associated viruses as helper viruses for their infection. Most of these satellite RNAs are noncoding RNAs, and in many cases, have been shown to alter the interaction of their helper viruses with their hosts. In only a few cases have the functions of these satellite RNAs in such interactions been studied in detail. In particular, work on the satellite RNAs of Cucumber mosaic virus and Turnip crinkle virus have provided novel insights into RNAs functioning as noncoding RNAs. These effects are described and potential roles for satellite RNAs in the processes involved in symptom intensification or attenuation are discussed. In most cases, models describing these roles involve some aspect of RNA silencing or its suppression, either directly or indirectly involving the particular satellite RNA.

Abstract:
ABSTRACT A satellite RNA of 836 nucleotides [excluding the poly(A) tail] depends on the bamboo mosaic potexvirus (BaMV) for its replication and encapsidation. The BaMV satellite RNA (satBaMV) contains a single open reading frame encoding a 20-kDa nonstructural protein (P20). The P20 protein with eight histidine residues at the C terminus was overexpressed in Escherichia coli. Experiments of gel retardation, UV cross-linking, and Northwestern hybridization demonstrated that purified P20 was a nucleic-acid-binding protein. The binding of P20 to nucleic acids was strong and highly cooperative. P20 preferred binding to satBaMV- or BaMV-related sequences rather than to nonrelated sequences. By deletion analysis, the P20 binding sites were mainly located at the 5′ and 3′ untranslated regions of satBaMV RNA, and the RNA-protein interactions could compete with the poly(G) and, less efficiently, with the poly(U) homopolymers. The N-terminal arginine-rich motif of P20 was the RNA binding domain, as shown by in-frame deletion analysis. This is the first report that a plant virus satellite RNA-encoded nonstructural protein preferentially binds with nucleic acids.

Abstract:
Viral satellite RNA associated with cucumber mosaic virus (CMV) is know to modulate CMV symptomology. Virulent CMV associated RNA 5 (CARNA 5) satellites may intensify crop disease. Naturally occurring variants of these satellites, however, attenuate CMV symptoms. Satellite transgenic tomato plants expressing the S-CARNA 5 or 1-CARNA 5 ameliorating forms of the satellite were evaluated under simulated CMV epidemic conditions in USDA–APHIS approved field trials. Trials conducted at Beltsville, Md., in 1994 and 1995 demonstrated that CMV can be effectively controlled under field conditions in satellite transgenic plants. Yields of transgenic lines infected with CMV were 50%–65% greater than that of non-transgenic infected controls. Yields of noninfected transgenic lines ranged from 5% greater than, to 33% less than, noninfected nontransgenic controls. Expression of CARNA 5 in inoculated transgenic plants greatly reduced CMV foliar symptoms and virus titers when compared to inoculated control plants. Levels of CARNA 5 were detected at varying levels in infected transgenic plants throughout the growing season. Virus or satellite was not detected in samples collected from tomato border plants and weeds growing inside and outside a nonhost crop border surrounding the test plot. Field tests conducted in 1996 will evaluate transgenic tomato plants with a double construct coding for the CMV coat protein gene and 1-CARNA 5 satellite.

Abstract:
Field trials of transgenic tomato plants expressing an ameliorative satellite RNA of cucumber mosaic virus (CMV) were conducted to test the efficacy of satellite-transgenic technology to protect against CMV infection. Three transgenic tomato lines derived from two susceptible genotypes were evaluated over two growing seasons for viral symptoms and titers, satellite RNA expression, and fruit yield. Satellite-transgenic lines exhibited mild or no CMV symptoms and low viral titers relative to nontransformed plants. A significant negative correlation between satellite RNA levels and disease severity was evident in transgenic lines. Total marketable yield of CMV-infected satellite-transgenic lines was 40 to 84% greater than that of CMV-infected parent lines. Importantly, yield of CMV-infected satellite-transgenic lines did not differ significantly from mock-inoculated parent lines. Risk assessment results demonstrated low levels of satellite RNA transmission within the test site and no evidence of satellite RNA-induced damage on surrounding plants.

Abstract:
Mixed infections of cucurbits by Cucumber mosaic virus (CMV) and potyviruses exhibit a synergistic interaction. Zucchini squash and melon plants coinfected by the potyvirus Zucchini yellow mosaic virus (ZYMV) and either Fny-CMV (subgroup IA) or LS-CMV (subgroup II) displayed strong synergistic pathological responses, eventually progressing to vascular wilt and plant death. Accumulation of Fny- or LS-CMV RNAs in a mixed infection with ZYMV in zucchini squash was slightly higher than infection with CMV strains alone. There was an increase in CMV (+) strand RNA levels, but no increase in CMV (-) RNA3 levels during mixed infection with ZYMV. Moreover, only the level of capsid protein from LS-CMV increased in mixed infection. ZYMV accumulated to similar levels in singly and mixed infected zucchini squash and melon plants. Coinfection of squash with the potyvirus Watermelon mosaic virus (WMV) and CMV strains increased both the Fny-CMV RNA levels and the LS-CMV RNA levels. However, CMV (-) strand RNA3 levels were increased little or not at all for CMV on coinfection with WMV. Infection of CMV strains (LS and Fny) containing satellite RNAs (WL47-sat RNA and B5*-sat RNA) reduced the accumulation of the helper virus RNA, except when B5*-sat RNA was mixed with LS- CMV. However, mixed infection containing ZYMV and the CMV strains with satellites reversed the suppression effect of satellite RNAs on helper virus accumulation and increased satellite RNA accumulation. The synergistic interaction between CMV and potyviruses in cucurbits exhibited different features from that documented in tobacco, indicating there are differences in the mechanisms of potyvirus synergistic phenomena.

Abstract:
The protein capsid of an icosahedral virus can be considered a natural scaffold system for the RNA genome which it packages. It is possible to manipulate the nature of this packaging to gain structural information regarding the encapsidated molecule. Satellite Tobacco Necrosis Virus (STNV), is a small T=1 plant satellite virus. It is possible to express and purify intact virus like particles recombinantly. The refined structure of these particles has been solved crystallographically to a resolution of 1.4 A, however no RNA density was visible within this structure. This structure has been re-solved within this thesis to low resolution, 6 A, revealing distinct density in addition to that of protein, attributable to RNA. The recombinant capsid is packaging non-self RNA and doing so with a degree of icosahedral order. The recognition sequence allowing STNV to package its own RNA genome specifically has not been identified. In an effort to achieve this, the process of SELEX has been implemented. Several sequences matching those of the STNV-1 genome have been identified indicating that this procedure has succeeded in selecting RNA sequences which mimic those expected to bind in nature. These matching sequences span the length of the genome, indicating that packaging may not be a result of binding to a single site on the RNA. As the STNV capsid is already designed to function as a scaffold for genomic RNA, it provides an obvious start point for the design of a more complex scaffold. The development of the STNV capsid to be of use as a macromolecular scaffold system is addressed within this thesis. Three hurdles associated with such a system have been identified and addressed by designing mutant STNV coat protein monomers. Upon expression and purifiCation differences in the biochemical properties between the wild type protein and the mutants have been identified.

ENGLISH ABSTRACT: Grapevine fanleaf virus (GFLV) is one of the oldest, most widespread and devastating viruses infecting grapevine, and occurs globally where Vitis vinifera is grown. In South Africa (SA) GFLV is predominant in the Breede River Valley, one of the highest wine producing regions in SA. To date, only three GFLV isolates have been completely sequenced internationally, and limited sequence information is available for SA GFLV isolates. In this study, the first full-length GFLV genome sequence from a South African isolate, GFLV-SAPCS3, was determined. Full-length sequences were used for phylogenetic analysis and revealed that the SA isolates are separate from other sequenced GFLV isolates. Full-length sequences were also used to investigate putative intra- and interspecies recombination events involving GFLV-SAPCS3 RNA1 and RNA2 between GFLV and Arabis mosaic virus (ArMV) isolates. Using two different recombination analysis software packages, the most notable of the putative recombination events involving GFLV-SAPCS3 indicated that the GFLV-SAPCS3 RNA2 5’ UTR might have evolved from an interspecies recombination event between GFLVF13- type and ArMV Ta-type isolates. The presence of satellite RNAs (satRNA) associated with South African GFLV isolates was also investigated. In a collaborative study (see Chapter 4 for details), more than a 100 GFLV- infected grapevine plants were screened for satRNAs. SatRNAs were present in only two plants, containing isolates GFLV-SACH44 and GFLV-SACH47. The full-length nucleotide sequences of the GFLV-SACH44 genomic RNAs 1 and 2, and the associated satRNA were determined. No significant sequence variation could be detected between the GFLV isolates that had the presence of a satRNA and those that had not. The GFLV-SACH44 RNA2 5’ UTR also had the same conserved sequence that was found in GFLVSAPCS3, which suggests that GFLV-SACH44, like GFLV-SAPCS3, may have arisen from a common ancestor, which may have originated from an interspecies recombination event. The GFLV-SACH44 satRNA was found to be more closely related to the ArMV large satRNA than to the satRNA associated with GFLV-F13. A full-length cDNA clone of GFLV-SACH44 satRNA was constructed and its replication and systemic spread in herbaceous hosts, when mechanically co-inoculated with two GFLV isolates as helper viruses, was demonstrated. Replication of the GFLV-SACH44 satRNA cDNA clone was however abolished when co-inoculated with an ArMV helper virus, even though it is phylogenetically more closely related to ArMV satRNAs. The full-length satRNA clones were modified to be used as vectors for expression and/or silencing of foreign genes, by inserting the green fluorescence protein (GFP) full-length or partial sequences downstream of the open reading frame of the satRNA. These constructs were cloned into a binary vector to allow for agro-infiltration into plants. Full-length cDNA clones of GFLV-SAPCS3 RNA1 and RNA2 were constructed to be used in conjunction with modified GFLV-SACH44 satRNA full-length clones. The full length GFLV-SAPCS3 RNA1 and RNA2 clones were however not infectious in Nicotiana benthamiana after agro-infiltration and therefore the evaluation of the modified satRNA expression and silencing constructs had to be aborted. Attempts to understand this failure revealed that, among other point mutations, four frameshifts had occurred in the RNA1 full-length clone, rendering the transcripts untranslatable, and hence noninfectious. Strategies to correct the mutations are discussed. Once these mutations have been corrected this study can continue in evaluating the use of the satRNA component for expression and silencing analysis.
AFRIKAANSE OPSOMMING: Grapevine fanleaf virus (GFLV) is een van die oudste, mees wydverspreide en mees verwoestende virusse wat wingerd affekteer en word wêreldwyd waar Vitis vinifera verbou word, gevind. In Suid Afrika (SA) kom GFLV veral in die Breederivier vallei, een van die mees produktiewe wyn-produserende areas in SA, voor. Tot dusver is daar net drie GFLV isolate waarvan die volledige nukleïensuurvolgorde internasionaal bepaal is. Die nukleïensuurvolgorde informasie vir SA GFLV isolate is redelik beperk. In hierdie studie was die eerste volledige nukleïensuurvolgorde van ‘n SA GFLV isolaat, GFLVSAPCS3, bepaal. Die volledige nukleïensuurvolgordes was vir filogenetiese analise gebruik, en vermeende intra- en interspesie rekombinasie gebeurtenisse, wat GFLVSAPCS3 RNA1 en RNA2 betrek, tussen GFLV en Arabis mosaic virus (ArMV) isolate was ondersoek. Twee verskillende rekombinasie-analise sagteware programme was gebruik en die noemenswaardigste van die vermeende rekombinasie gebeurtenisse, met betrekking tot GFLV-SAPCS3, het aangedui dat die GFLV-SAPCS3 RNA2 5’ ontransleerde streek (UTR) waarskynlik van ‘n interspesie rekombinasie gebeurtenis tussen ‘n GFLV-F13-tipe en ‘n ArMV-Ta-tipe isolaat ontwikkel het. Die teenwoordigheid van satelliet RNAs (satRNAs), wat met SA GFLV isolate geassosieer is, was ook ondersoek. Meer as ‘n 100 GFLV ge-infekteerde wingerd plante was in ‘n samewerkingsprojek (sien Hoofstuk 4 vir besonderhede) getoets vir die teenwoordigheid van satRNAs. SatRNAs was net in twee plante teenwoordig, in isolate GFLV-SACH44 en GFLV-SACH47. Die vollengte nukleïensuurvolgordes van GFLVSACH44 RNA1, RNA2 en geassosieerde satRNA was bepaal. Geen beduidende volgorde variasie tussen die GFLV isolate wat satRNAs bevat het, en die GFLV isolate sonder satRNA was waargeneem nie. Die GFLV-SACH44 RNA2 5’ UTR het ook die gekonserveerde volgorde, wat in GFLV-SAPCS3 teenwoordig was, gehad en dit dui daarop dat GFLV-SACH44, soos GFLV-SAPCS3, van dieselfde stamvader, wat tydens ‘n vorige rekombinasie gebeurtenis ontstaan het, mag ontwikkel het. Die GFLVSACH44 satRNA was meer naverwant aan die ArMV satRNAs as aan die satRNA, wat met GFLV-F13. ‘n Vollengte cDNA kloon van die GFLV-SACH44 satRNA was ontwikkel en die replisering en sistemiese verspreiding in sagte plante, nadat dit met twee GFLV isolate as helper virusse saam ge-inokuleer was, was gedemonstreer. Replisering van die GFLV-SACH44 satRNA cDNA kloon was egter ontwrig toe dit saam met ‘n ArMV helper virus saam ge-inokuleer was, al is dit filogeneties meer verwant aan ArMV satRNAs. Die vol-lengte satRNA klone was gemodifiseer om as vektore vir uitdrukking en/of uitdowing van transgene te dien, deur om vol-lengte of gedeeltelike groen fluoressensie proteïen (GFP) nukleïensuurvolgordes aan die einde van die satRNA leesraam te koppel. Hierdie konstrukte was in ‘n binêre vektor gekloon om agroinfiltrasie in plante toe te laat. Vol-lengte cDNA klone van GFLV-SAPCS3 RNA1 en RNA2 was ontwikkel om in samewerking met die gemodifiseerde GFLV-SACH44 satRNA konstrukte gebruik te word. Die vol-lengte GFLV-SAPCS3 RNA1 en RNA2 klone het egter nie in Nicotiana benthamiana gerepliseer na agro-infiltrasie nie, daarom was die evaluasie van die gemodifiseerde satRNA konstrukte gestaak. Pogings om die mislukking te verstaan, het daarop gewys dat, behalwe punt mutasies, vier leesraam versteurings in die RNA1 vollengte kloon voorgekom het, wat ontransleerbare transkripte, en dus nie-repliserende konstrukte tot gevolg gehad het. Strategieë om die mutasies te korrigeer is bespreek. Sodra die mutasies gekorrigeer is, kan die studie voortgaan om te evalueer of die satRNA komponent vir uitdrukking en uitdowing analise gebruik kan word.

Abstract:
Le centromère est une structure chromosomique spécialisée comportant un type unique de chromatine, nécessaire pour la ségrégation correcte des chromosomes pendant la mitose. L'assemblage et la fonction des centromères exigent l'association dynamique d'une grande variété de protéines au cours du cycle cellulaire. Par ailleurs, des données de plus en plus abondantes montrent que les ARNs non-codant sont des composants intégraux de la chromatine et contribuent à son organisation structurale. Les ARNs centromériques que nous avons récemment caractérisés sont transcrits à partir des répétitions des centromères murins. Leur accumulation sur les chromocentres nous a permis de les proposer comme facteur d'assemblage ou de maintien des protéines centromériques, nécessaires à la ségrégation correcte des chromosomes. Nos résultats montrent que les ARNs centromériques s'accumulent principalement en phase G2/M, au cours de laquelle est assemblé le complexe passager du centromère. Ces ARNs sont des composants intégrales de la chromatine centromérique: ils interagissent avec CENP-A et font partie du complexe passager au début de la mitose. De plus, l'association des protéines passagères Aurora B et Survivin au niveau de la chromatine centromérique et l'activité de la kinase Aurora B dépendent d'un ARN. Enfin, des tests fonctionnels indiquent que l'activité enzymatique de Aurora B dépend de la présence des ARNs centromériques. Ces données suggèrent que les transcrits centromériques pourraient jouer un rôle important dans l'assemblage et la fonction du centromère en recrutant et/ou stabilisant Aurora B au niveau de la chromatine associée à CENP-A et en réglant son activité enzymatique
The centromeres of eukaryotic chromosomes are genomic regions featuring a unique, specific chromatin architecture that is necessary for proper chromosome segregation during mitosis. While there is evidence that the assembly and highly specialized fonction of centromeric chromatin domains require the dynamic association of a large variety of proteins during various stages of the cell-cycle, it is now becoming clear that non-coding RNA are integral components of chromatin and contribute to its structural organization. We recently described new RNA, transcribed from murine centromeric minor satellite repeats, which localize on chromocenters. We now considered the implication of these RNA in recruiting and/or stabilizing rfconucleoprotein complexes located at centromeric regions and their functional dynamics during cell cycle. We reported that levels of minor satellite RNA vary during cell cycle progression, accumulating in G2/M phase, concomitantly with the localization of the chromosomal passenger complex to the centromere. We showed that minor satellite RNA are components of CENP-A chromatin and interact with proteins of the chromosomal passenger complex at the onset of mitosis. Both interactions between endogenous passenger proteins Aurora B and Survivin within centromeric chromatin and Aurora B kinase activity are sensitive to RNaseA. More importantly, this Aurora B kinase activity can be specifically rescued by restitution of minor satellite RNA. Together, our data provide new insights into thé implication of minor satellite RNA in the establishment of a functional centromere, by regulating Aurora B association with CENP-A-associated domains and enzymatic function

Abstract:
Parmi les nombreuses maladies virales qui affectent la vigne, la maladie du court-noue est l'une des plus graves et des plus repandues. Le grapevine fanleaf virus (gflv) et l'arabis mosaic virus (armv) sont deux nepovirus responsables de cette maladie. Les moyens de lutte actuels contre cette maladie font essentiellement appel a l'utilisation de plantes certifiees indemnes de virus (selection sanitaire) et a des traitements chimiques des sols pour eliminer les nematodes vecteurs, mais les nematicides employes sont couteux, polluants et pas toujours efficaces. Disposant de plusieurs pathotypes de court-noue qui se distinguent par leur virulence sur vigne et sur hotes herbacess, nous avons envisage d'utiliser les caracteres d'hypovirulence comme nouvelles methodes de lutte. C'est pourquoi, une etude moleculaire de la protection croisee entre isolats hypo- et hypervirulents a ete realisee sur chenopodium quinoa. Cette plante herbacee permet des experiences rapides sur vigne. Elles ont montre que dans les plantes premunies la synthese de la capside et des rna de l'isolat hyperagressif est diminuee ou meme parfois inhibee. Une application agronomique de la premunition a la vigne est prevue. Une autre approche est liee a la presence de rna satellite dans certains isolats.

Abstract:
Recently, some components and payload systems installed in satellites are exposed to various disturbance sources, such as the reaction wheel assembly, the control moment gyro, coolers, and others. Because there is low damping in space, the continuous microvibration causes the degradation of the performance of various payload systems. Therefore, the development of a practical isolation system that shields against microvibration are very important and the author is on the way to developing the microvibration isolation system for the improvement on the performance of the optical payload. In order to develop appropriate microvibration isolation device for a specific payload, it is necessary to understand vibration characteristics of the main disturbance sources; modeling and analysis of disturbance sources including reaction wheel assembly and control moment gyros have been studied by many researchers. However, there are practical difficulties to obtain and perform an experiment with real flight model (FM) reaction wheel assembly and control moment gyros because of expensive price and security reasons. Generally, the disturbance characteristics of a prototype of the reaction wheel assembly or control moment gyros are significantly different from those of FM ones even when the reaction wheel type, size and wheel speed are the same. Therefore, in order to facilitate the microvibration isolation experiment during the satellite development process, this paper proposes a microvibration emulator that could generate the real disturbance spectrums of FMs. Note that the disturbance profiles are quite complex, consisting of several higher harmonics, and also changing for varying operational wheel speeds. The disturbance characteristics of FMs are typically measured in advance. First an analytical model for the RWA is presented and the development procedure for the emulator is also described. The performance of the first prototype emulator is demonstrated.

Abstract:
This paper proposes a novel dynamic model of a Reaction Wheel Assembly (RWA) based on the Two-Input Two-Output Port framework, already presented by the authors. This method allows the user to study a complex system with a sub-structured approach: each sub-element transfers its dynamic content to the other sub-elements through local attachment points with any set of boundary conditions. An RWA is modelled with this approach and it is then used to study the impact of typical reaction wheel perturbations on a flexible satellite in order to analyze the micro-vibration content for a high accuracy pointing mission. This formulation reveals the impact of any structural design parameter and highlights the need of passive isolators to reduce the micro-vibration issues. The frequency analysis of the transfer between the disturbance sources and the line-of-sight (LOS) jitter highlights the role of the reaction wheel speed on the flexible modes migration and suggests which control strategies can be considered to mitigate the residual micro-vibration content in order to fulfil the mission performances.
