Abstract:
In order to solve the problem that the speed of augmenting in NEAT algorithm is obviously not fast enough. We bring in the hybridization scheme. The scheme mainly gets new progeny chromosomes by combining parents ones. But it will probably bring in abnormal genes. As we record the time stamp for every gene, we can easily ensure that those genes are the same, so that we can simply get those completely reasonable hybrid chromosomes. We mainly use the time stamp of every gene to record information and make progeny chromosomes.

Abstract:
AbstractEstimates suggest that about 16% of bird species hybridize in the wild. This number is based on two main sources: the Handbook of Avian Hybrids of the World by Eugene McCarthy and the online Serge Dumont Bird Hybrids Database. Although both sources provide supporting references for the documented hybrids, the reliability of these references has not been systematically assessed. In this paper, I introduce a scoring scheme based on three criteria that are weighted based on their reliability, namely field observations or photographs (1 point), morphological analyses (2 points), and genetic analyses (3 points). The final tally of these three criteria (ranging from 0 to 6 points) will indicate the level of confidence for a particular hybrid. I test this scoring scheme on the Neotropical bird family Tinamidae (tinamous), in which several putative hybrids have been reported. My analysis revealed one well-documented case (Crypturellus boucardi × C. cinnamomeus) and three doubtful records that require further investigation. These findings highlight the need for thoroughly scrutinizing the sources supporting avian hybrids. The scoring system clearly illustrates its usefulness and can be easily applied to other taxonomic groups to increase the reliability of documenting interspecific hybrids.

Abstract:
Background: As the standard for the exchange of data over the World Wide Web, it is important to ensure that the eXtensible Markup Language (XML) database is capable of supporting not only efficient query processing but also capable of enduring frequent data update operations over the dynamic changes of Web content. Most of the existing XML annotation is based on a labeling scheme to identify each hierarchical position of the XML nodes. This computation is costly as any updates will cause the whole XML tree to be re-labelled. This impact can be observed on large datasets. Therefore, a robust labeling scheme that avoids re-labeling is crucial. Method: Here, we present ORD-GAP (named after Order Gap), a robust and persistent XML labeling scheme that supports dynamic updates. ORD-GAP assigns unique identifiers with gaps in-between XML nodes, which could easily identify the level, Parent-Child (P-C), Ancestor-Descendant (A-D) and sibling relationship. ORD-GAP adopts the OrdPath labeling scheme for any future insertion. Results: We demonstrate that ORD-GAP is robust enough for dynamic updates, and have implemented it in three use cases: (i) left-most, (ii) in-between and (iii) right-most insertion. Experimental evaluations on DBLP dataset demonstrated that ORD-GAP outperformed existing approaches such as ORDPath and ME Labeling concerning database storage size, data loading time and query retrieval. On average, ORD-GAP has the best storing and query retrieval time. Conclusion: The main contributions of this paper are: (i) A robust labeling scheme named ORD-GAP that assigns certain gap between each node to support future insertion, and (ii) An efficient mapping scheme, which built upon ORD-GAP labeling scheme to transform XML into RDB effectively.

Abstract:
We present a hybridization of the accelerated gradient method with two vector directions. This hybridization is based on the usage of a chosen three-term hybrid model. Derived hybrid accelerated double direction model keeps preferable properties of both included methods. Convergence analysis demonstrates at least linear convergence of the proposed iterative scheme on the set of uniformly convex and strictly convex quadratic functions. The results of numerical experiments confirm better performance profile in favor of derived hybrid accelerated double direction model when compared to its forerunners.

Abstract:
Dans cette thèse, nous nous intéressons à l’amélioration du schéma de Yee pour traiter demanière plus efficace et pertinente les problèmes industriels auxquels nous sommes confrontés à l’heureactuelle. Pour cela, nous cherchons avant tout à diminuer les erreurs numériques de dispersion et àaméliorer les modélisations des géométries courbes ainsi que des réseaux de câbles. Pour répondre àces besoins, une solution basée sur un schéma Galerkin discontinu pourrait être envisagée. Toutefois,l’utilisation d’une telle technique sur la totalité du volume de calcul est relativement coûteuse. De plus,la prise en compte de structures filaires sur un tel schéma n’est pas encore opérationnelle. C’est pourquoi,dans l’optique d’avoir un outil industriel, et après une étude bibliographique, nous nous sommes plutôtorientés sur l’étude d’un schéma éléments finis (FEM) sur maillage cartésien qui possède toutes lesbonnes propriétés du schéma de Yee. Notamment, à l’ordre d’approximation spatiale égal à 0 ce schémaFEM est exactement le schéma de Yee, et, pour des ordres supérieurs, il permet de réduire fortementl’erreur de dispersion numérique de ce dernier. Dans le travail de cette thèse, pour ce schéma, nous avons notamment donné un critère de stabilité théorique, étudié sa convergence théorique et fait une analyse de l’erreur de dispersion. Pour tenircompte des possibilités d’ordre d’approximation spatiale variable par direction, nous avons mis en placeune stratégie d’affectation des ordres suivant le maillage donné. Ceci nous a permis d’obtenir un pas detemps optimal pour une précision souhaitée tout en réduisant les coûts de calcul. Après avoir porté ceschéma sur des machines de production, différents problèmes de CEM, antennes, IEM ou foudre ont ététraités afin de montrer les avantages et le potentiel de celui-ci. En conclusion de ces expérimentationsnumériques, il s’avère que la méthode est limitée par le manque de précision pour prendre en comptedes géométries courbes. Afin d’améliorer cela, nous avons proposé une hybridation entre ce schéma et leschéma GD que l’on peut étendre aux autres schémas comme les méthodes différences finies (FDTD) etvolumes finis (FVTD). Nous avons montré que la technique d’hybridation proposée conserve l’énergie etest stable sous une condition que nous avons évaluée de manière théorique. Des exemples de validationont ensuite été montrés. Enfin, pour tenir compte des réseaux de câbles, un modèle de fils minces d’ordred’approximation spatiale élevé a été proposé. Malheureusement, celui-ci ne peut pas couvrir l’ensembledes cas industriels et pour remédier à cela, nous avons proposé une hybridation de notre approche avecune équation de ligne de transmission. L’intérêt de cette hybridation a été montré sur un certain nombred’exemples, que nous n’aurions pas pu traiter par un modèle de structure filaire simple
In this thesis, we study the improvement of the Yee’s scheme to treat efficiently and in arelevant way the industrial issues we are facing nowadays. For that, we first of all try to reduce thenumerical errors of dispersion and then to improve the modeling of the curved surfaces and of theharness networks. To answer these needs, a solution based on a Galerkin Discontinuous (GD) methodhas been first considered. However, the use of such method on the entire modeling volume is quite costly ;moreover the wires are not taken into account in this method. That is the reason why, with the objectiveof an industrial tool and after a large bibliographic research, we headed for the study of finite elementsscheme (FEM) on a Cartesian mesh which has all the good properties of the Yee’s scheme. Especially,this scheme is exactly the Yee’s scheme when the spatial order of approximation is set to zero. Forthe higher orders, this new scheme allows to greatly reduce the numerical error of dispersion. In theframe of this thesis and for this scheme, we give a theoretical criterion of stability, study its theoreticalconvergence and we perform an analysis of the error of dispersion. To take into account the possibilityof the variable spatial orders of approximation in each direction, we put in place a strategy of orderaffectation according to the given mesh. This strategy allows to obtain an optimal time step for a givenselected precision while reducing the cost of the calculations. Once this new scheme has been adaptedto large industrial computing means, different EMC, antennas, NEMP or lightning problems are treatedto demonstrate the advantages and the potential of this scheme. As a conclusion of these numericalsimulations we demonstrate that this method is limited by a lack of precision when taking into accountcurved geometries. To improve the treatment of the curved surfaces, we propose an hybridization between this scheme andthe GD scheme. This hybridization can also be applied to other methods such as Finite Differences(FDTD) or Finite Volumes (FVTD). We demonstrate that the technique of hybridization proposed,allows to conserve the energy and is stable under a condition that we study theoretically. Some examplesare presented for validation. Finally and to take into account the cables, a thin wire model with a highorder of spatial approximation is proposed. Unfortunately, this model does not allow to cover all theindustrial cases. To solve this issue we propose an hybridization with a transmission line method. Theadvantage of this hybridization is demonstrated thanks to different cases which would not have beenfeasible with a more simple thin wire method

Abstract:
Dans ce mémoire, nous présentons une stratégie basée sur une approche hybridedans le domaine temporel, couplant une méthode de résolution des équations de Maxwelldans le domaine 3D (FDTD) avec une méthode de résolution des équations de ligne detransmission, afin de pouvoir simuler des problèmes électromagnétiques de grande échelle. Lemémoire donne les éléments d’hybridation pour deux cadres d’utilisation de cette approche :une approche multi-domaine et une approche multi-résolution ou d’échelle.L’approche multi-domaine est une extension de la méthode FDTD 3D à plusieurs sousdomainesreliés par des structures filaires sur lesquelles on résout une équation de lignes detransmission par un formalisme FDTD 1D. La difficulté est d’abord d’avoir une définitionimplicite du champ électromagnétique dans la théorie des lignes de transmission, et d’autrepart de prendre en compte les effets du sol sur les courants induits au niveau des lignes etsur les champs électromagnétiques.L’approche multi-résolution ou d’échelle est conçue pour étendre les capacités de la méthodeFDTD au traitement du routage de câbles complexes ayant une section plus petite quela taille de la cellule. Ce mémoire présente différentes techniques pour évaluer les paramètresde la ligne, basées sur la résolution d’un problème de Laplace 2D, ainsi qu’une méthode decouplage champs/câbles basée sur le courant de mode commun.L’ensemble de ce travail nous a permis de proposer une méthode numérique efficace pourcalculer les effets électromagnétiques induits par une source (type onde plane ou dipolaire)sur des sites de grande dimension, composés de plusieurs bâtiments reliés entre eux par unréseau de câbles. Dans ce cadre une application à la foudre a été réalisée
In this thesis, we present a strategy based on a hybrid approach in the timedomain, by coupling 3D method (FDTD) with a multi-conductors transmission line (MTL)method, in order to simulate complex large scale electromagnetic problems. This reportgives the theoretical and numerical elements for coupling these approaches for two kindof problems, which are the multi domains approach and the multi scale approach. Themultiple domains approach is an extension of the classical FDTD method taking into accountseveral 3D subdomains, interconnected by a wire network, on which a 1D transmission lineformalism is used. The main issues are, on one hand to have an implicit expression ofthe electromagnetic field in the transmission line approach, and on the other hand to beable to take into account the ground effects on the induced currents, on the transmissionline parameters and on the electromagnetic field. The multi scale approach is developed toextend the capabilities of FDTD to deal with complex cables routing. We assume that thecross section of the cables are smallest than the cell size, and in these problems, the 1Dtransmission line problem is physically included in the 3D global computational domain.The work done in this thesis leaded to a new field to transmission line coupling based onthe common mode current, and an evaluation of the transmission. line parameters basedon a Laplace equation resolution in 2D. In this work, we have elaborated and proposedefficient numerical strategies for the computation of electromagnetic induced effects on largeand complex sites, composed of several interconnected distant buildings.

Abstract:
La détection d'objets enfouis, qu'il s'agisse d'engins explosifs dans un contexte militaire ou de structures archéologiques dans un contexte civil, constitue une préoccupation majeure. En termes de télédétection radar, les systèmes aéroportés, comme le radar à synthèse d’ouverture (SAR), permettent une imagerie non destructive des sous-sols tout en offrant la possibilité d'explorer de vastes zones avec une distance de sécurité par rapport à celles-ci. Cependant, leur efficacité pour la détection d’objets enfouis dépend de nombreux facteurs, tels que les caractéristiques diélectriques du sol, qui affectent la profondeur de pénétration des ondes électromagnétiques, la nature des cibles, le type d'émetteur... Une étude préliminaire, permettant de prédire la réponse des cibles en fonction des caractéristiques des systèmes et de la scène, serait alors un outil précieux pour évaluer les capacités de détection avant d'engager des campagnes de mesures.Cette thèse s'inscrit dans ce contexte, en se concentrant sur la recherche, le développement et l'optimisation d'un outil de simulation numérique destiné à évaluer précisément la surface équivalente radar (SER) d'objets enfouis. L'approche proposée repose sur une stratégie d'hybridation de solveurs FVTD (Finite Volume Time Domain) appliquée à des maillages hybrides cartésiens / non-structurés dans l'optique d'optimiser les coûts de calcul. En particulier, ces maillages hybrides permettent une représentation conforme des géométries courbes et une discrétisation spatiale localement adaptée aux vitesses de propagation des ondes électromagnétiques dans les différents milieux de la scène de calcul. La procédure d'obtention de ces maillages, basée sur le découpage du domaine de calcul en sous-domaines est détaillée, et les solveurs FVTD utilisés sont décrits en soulignant les choix effectués pour optimiser leur efficacité. L'implémentation des modèles permettant une description représentative du sol, la prise en compte précise d'une source de type onde plane et le calcul de champs lointains en présence d'un milieu avec pertes, est également abordée. L'hybridation des solveurs FVTD via une stratégie multi-domaines / multi-méthodes est présentée en détail, en mettant l'accent sur l'architecture logicielle proposée et en précisant la stabilité de la solution hybride ainsi que les enjeux de l'hybridation. Enfin, une comparaison de résultats simulés avec des données expérimentales obtenues dans le cadre d'une campagne de mesures mise en œuvre pour cette thèse, fournit une première appréciation des performances de l'outil de simulation développé. Pour conclure, la thèse met en avant la possibilité d'utiliser cet outil pour étudier l'impact des paramètres de configuration des systèmes radar sur la SER d'objets enfouis pour des scénarios donnés
The detection of buried objects, whether explosive devices in a military context or archaeological structures in a civilian context, is a major concern. In radar remote sensing, airborne systems such as Synthetic Aperture Radar (SAR) allow non-destructive imaging of subsurface environments while offering the possibility of exploring large areas from a safe distance. However, their effectiveness in detecting buried objects depends on many factors, such as the dielectric properties of the soil, which affect the penetration depth of electromagnetic waves, the nature of targets, and the type of transmitter... A preliminary study that predicts target response based on system and scene characteristics would be a valuable tool for assessing detection capabilities before launching measurement campaigns.This thesis addresses such context by focusing on the research, development, and optimization of a numerical simulation tool designed to accurately evaluate the radar cross-section (RCS) of buried objects. The proposed approach is based on a hybridization strategy using Finite Volume Time Domain (FVTD) solvers applied to hybrid Cartesian/unstructured meshes to optimize computational costs. More specifically, these hybrid meshes allow for a conformal representation of curved geometries and spatial discretization adapted to the varying electromagnetic wave propagation speeds in different media. The procedure for generating these meshes, based on the subdivision of the computational domain into subdomains is detailed, and used FVTD solvers are described, highlighting the choices made to optimize their efficiency. The implementation of models for representative soil description, accurate handling of plane-wave sources, and far-field calculations in lossy media are also addressed. The hybridization of FVTD solvers through a multi-domain/multi-method strategy is presented in detail, emphasizing proposed software architecture, the stability of the hybrid solution, and the challenges of hybridization. Finally, a comparison of simulated results with experimental data obtained during a measurement campaign conducted for this thesis provides an initial assessment of the performance of developed simulation tool. In conclusion, this thesis highlights the potential of this tool in studying the impact of radar system configuration parameters on buried objects RCS in given scenarios

In this article, we will put forward the number value representative that interface technology flows in the limited volume formula of Euler equation preface. This rule is based on wave type produced in Riemann question, and the rule that further combine Roe, Osher and HLLE build constructing. Adopt Roe rule to handle the way when the non-linear wave in Riemann problem is for the seismic wave; And when the non-linear wave is in order to expand the slope, use Osher rule handle way, so as can similar to the wave expression method unanimously with primitive Riemann issue. In addition, spread the enough seismic wave of stability to consider HLLE rule exposed to the discontinous wave in the middle of not having in number value while calculating. In order to improve the diffusion of number value. Analyze that can know, the calculation rule that this text puts forward can obtain the relatively rational middle state via the middle state of general Riemann question, cooperate with the wave type to distribute and can get the fast approximate solution of the middle state at the same time. Utilize several more results of calculation of real cases and verify the feasibility of calculating case that this text put forward. Including moving contact, moving shock, simple expansion wave, Sod’s problems, Lax’s problems, colliding and separating flows. Consider that simple shear and moving shock problems two-dimentionally at the same time. The result of calculation can know the rule that this text puts forward can really improve accuracy and stability of calculating simulation.

Abstract:
AbstractDifferent crops are harvested in Senegal at different periods throughout the year. Therefore, crop residues are constantly available, and there is potential for recycling these residues to produce energy. However, most of these crop residues are often burned or leftover in fields. This chapter assesses the energy potential of five crop residues available in Senegal, in terms of raw material quantities and calorific values, in order to propose adequate valorization schemes. The methodology of the study is based on a review of scientific literature in the field, the processing of data collected from the national specialized agencies, and laboratory tests of pellets manufactured from these residues. The experiments also propose techniques of hybridization in pelleting. The results show the feasibility of combining crop residues to produce pellets, with improved energy characteristics. They also demonstrate that pellets from crop residues can substitute part of industries’ heat demand with the combustion technology and part of rural communities’ electricity demand with the gasification technology.

Abstract:
This chapter assesses the hybrid orbital description of bonding. The hybrid orbital view of bonding is a localized view that involves the construction of two-centre, two-electron bonds. Hybrid orbitals for an atom are linear combinations of its atomic orbitals combined in appropriate proportions so that they point towards the attached atoms or groups for that atom. An appropriate hybridization scheme for any particular atom within a molecule is linked with its geometry. The linear geometry is associated with sp hybridization, the trigonal geometry is associated with sp2 hybridization, and the tetrahedral geometry is associated with sp3 hybridization. The chapter then considers benzene, which is one of the most important molecules in organic chemistry.

A Dielectrophoresis (DEP) based Surface Microfluidic (SMF) device has been successfully configured to facilitate multiplexed DNA hybridization assay. In this paper, we have demonstrated the utility of a 2×2 multiplexed DEP based droplet dispensing and conveyance schemes to manipulate sub-nanoliter DNA sample droplets and facilitate high throughput applications. To quantify and study various aspects of the multiplexed DNA hybridization assay, a photo multiplier tube (PMT) was utilized to optically monitor the individual droplets. Applications of the proposed assay scheme are envisioned in generalization towards an MxN matrix which can conduct numerous biochemical assays in a parallel, automated fashion, consuming minimal quantities of chemical and biochemical reagents and providing means for reliable and low cost bio-diagnostics.

Abstract:
A plug-in hybrid electric vehicle (PHEV) relies on relatively larger storage batteries than conventional hybrid electric vehicles. The characteristics of PHEV batteries, as well as hybridization of the PHEV battery with the engine and electric motor, play an important role in the design and potential adoption of PHEVs. To exhaustively evaluate all the possible combinations of available types of batteries, motors and engines, the total computational time is prohibitive. This work proposed an integrated optimal design strategy to address this problem. The recently developed Pareto set pursuing (PSP) multi-objective optimization approach is employed to perform optimal hybridization. Each PHEV with chosen battery, motor and engine is designed for optimal component sizing using the Powertrain System Analysis Toolkit (PSAT) software. The methodology is demonstrated with the Toyota Prius PHEV20: PHEV version sized for 20 miles (32.1 km) of all electric range (AER). Fuel economy, operating cost, and green house gases emissions are simultaneously optimized from 4,480 possible combinations of design parameters: 20 batteries, 14 motors, and 16 engines. The hybridization optimization is performed on two different drive cycles—Urban dynamometer driving schedule (UDDS) and Winnipeg weekday duty cycle (WWDC). It was found that battery, motor, and engine work collectively to define an optimal hybridization scheme and the optimal hybridization scheme varies with each driving cycle. The proposed method and software platform could be applied to optimize other powertrain designs.

Abstract:
For hybrid electric vehicles (HEVs), especially for diesel-electric hybrid vehicles, the low exhaust gas temperature induced by the hybridization and fuel economy optimization will bring significant impact on the performance of the exhaust gas aftertreatment systems, and may consequently lead to violation of the tailpipe emission constraints. To investigate the influence of diesel powertrain hybridization on the aftertreatment system and tailpipe emissions, an integrated HEV model is established by incorporating the thermodynamics models of the aftertreatment systems. This comprehensive model is able to predict engine-out nitrogen oxides (NOx) concentration, exhaust gas temperature, and to describe the temperature dynamics in the aftertreatment systems. A static map of selective catalytic reduction (SCR) system temperature-dependent de-NOx efficiency is utilized, so that the tailpipe NOx can be predicted. To investigate the tradeoff between fuel consumption and emissions for diesel HEV with aftertreatment systems, a preliminary study is carried out on optimally balancing both aspects via a model predictive control scheme. This controller is designed with an explicit consideration of HEV tailpipe NOx emission constraint. The simulation results show that the HEV tailpipe NOx emissions can be regulated by slightly sacrificing the fuel economy.

Abstract:
Abstract Hybrid Lagrangian-Eulerian solvers combine the convective and compactness advantages of vortex methods with the spatial anisotropy and boundary-resolving advantages of Eulerian methods to create flexible solvers capable of adequately capturing thin boundary layers while still maintaining wake vortex coherency for unsteady incompressible flow in complex geometries. The present paper details a new hybrid method which combines, in one open-source package, a novel, compact, high-order Eulerian scheme for vorticity transport to predict the flow in the near-boundary region with a grid-free, unremeshed, Lagrangian Vortex Particle Method (LVPM) for the off-boundary vorticity-containing region. This paper focuses on the hybridization of the two methods and demonstrates its effectiveness on two canonical benchmarks: flow in 2-D lid-driven cavity at Re = 1,000 and impulsively started flow over a circular cylinder at Re = 9,500. In each case, the hybrid method improves upon a pure LVPM and uses far fewer cells than a purely Eulerian scheme. In addition, the size of the associated Eulerian region is greatly reduced compared to previous hybrid methods.

Abstract:
Abstract Aircraft electrification for propulsion is a promising way to alleviate the negative environmental impact of conventional carbon-powered aviation. Inclusion of the electrical powertrain aims to enhance design freedom allowing for more efficient power systems and operational schemes. In this work a design space exploration is performed aiming to derive power management guidelines based on aircraft environmental performance. A 19-passenger commuter aircraft employing the series/parallel partial hybrid-electric architecture is examined. Two underwing-mounted turboprop engines are combined with a boundary layer ingestion fan mounted in the aircraft aft and powered by an electrical drive. The primary electrical energy source is a battery system. A multi-disciplinary framework is utilized, comprising modelling approaches for multi-point thermal engine design, physics-based electrical component sizing and performance, aircraft sizing, mission design, and environmental assessment. The investigation revealed that the reference designed hybrid-electric configuration with entry-into-service 2035-assumed technologies yields roughly 18% improvement in block consumption and emissions, but an 8% increase in maximum take-off weight, compared to its 2014 conventional counterpart. The design space exploration for an optimal power management scheme indicated a minimum ratio of 1:1.35 between cruise and design point hybridization power. However, even the optimally operated hybrid aircraft showcases worse environmental performance compared to the conventional design of same entry-into-service date. The investigation has revealed that the complex powertrain and hybrid architecture selected may be more suitable for larger class aircraft, with the accumulated performance benefits reaching the order of 5% for the hybrid designs explored under relaxed top-level constraints.

Abstract:
Pelargonium (Geranium) is the number one pot plant in many areas of the United States and Europe. Israel and the U.S. send to Europe rooted cuttings, foundation stocks and finished plants to supply a certain share of the market. Geraniums are propagated mainly vegetatively from cuttings. Consequently, viral diseases have been and remain a major threat to the production and quality of the crop. Among the viruses isolated from naturally infected geraniums, 11 are not specific to Pelargonium and occur in other crops while 6 other viruses seem to be limited to geranium. However, several of these viruses are not sufficiently characterized to conclude that they are distinct agents and their nomenclature and taxonomy are confusing. The ability to separate, distinguish and detect the different viruses in geranium will overcome obstacles te developing effective detection and certification schemes. Our focus was to further characterize some of these viruses and develop better methods for their detection and control. These viruses include: isolates of pelargonium line pattern virus (PLPV), pelargonium ringspot virus (PelRSV), pelargonium flower break virus (PFBV), pelargonium leaf curl (PLCV), and tomato ringspot virus (TomRSV). Twelve hybridoma cell lines secreting monoclonal antibodies specific to a geranium isolate of TomRSV were produced. These antibodies are currently being characterized and will be tested for the ability to detect TomRSV in infected geraniums. The biological, biochemical and serological properties of four isometric viruses - PLPV, PelRSV, and PFBV (and a PelRSV-like isolate from Italy called GR57) isolated from geraniums exhibiting line and ring pattern or flower break symptoms - and an isolate ol elderbeny latent virus (ELV; which the literature indicates is the same as PelRSV) have been determined Cloned cDNA copies of the genomic RNAs of these viruses were sequenced and the sizes and locations of predicted viral proteins deduced. A portion of the putative replicase genes was also sequenced from cloned RT-PCR fragments. We have shown that, when compared to the published biochemical and serological properties, and sequences and genome organizations of other small isometric plant viruses, all of these viruses should each be considered new, distinct members of the Carmovirus group of the family Tombusviridae. Hybridization assays using recombinant DNA probes also demonstrated that PLPV, PelRSV, and ELV produce only one subgenomic RNA in infected plants. This unusual property of the gene expression of these three viruses suggests that they are unique among the Carmoviruses. The development of new technologies for the detection of these viruses in geranium was also demonstrated. Hybridization probes developed to PFBV (radioactively-labeled cRNA riboprobes) and to PLPV (non-radioactive digoxigenin-labeled cDNAs) were generally shown to be no more sensitive for the detection of virus in infected plants than the standard ELISA serology-based assays. However, a reverse transcriptase-polymerase chain reaction assay was shown to be over 1000 times more sensitive in detecting PFBV in leaf extracts of infected geranium than was ELISA. This research has lead to a better understanding of the identity of the viruses infecting pelargonium and to the development of new tools that can be used in an improved scheme of providing virus-indexed pelargonium plants. The sequence information, and the serological and cloned DNA probes generated from this work, will allow the application of these new tools for virus detection, which will be useful in domestic and international indexing programs which are essential for the production of virus-free germplasm both for domestic markets and the international exchange of plant material.
