Abstract

Pome fruit viruses have been mainly identified from commercialised cultivars presenting disease symptoms. Their significant impact on fruit yield and quality triggered their identification and characterization ex post. For example, the infection of certain virulent strains of apple stem pitting virus (ASPV) was detected due to necrosis development between susceptible scions and/or rootstocks (rootstock incompatibility). In this context, the diversity of viruses infecting pome fruit trees is still largely underestimated and it is worth additional investigation. The goal of this project is to evaluate the presence of known and unknown viruses infecting ancient cultivars of apple and pear. Leaf samples were taken from six apple cultivars (‘Gravenstein’, ‘Pomme Pellone’, ‘Délices de Beignée’, ‘Reinette Meurens’, ‘Belle de Boskoop’, and ‘Joseph Musch’) and five pear cultivars (‘Poire Cuisse Madame’, ‘Jeanne d’Arc’, ‘Poire Rougette’, ‘Bronzée d’Enghien’, and ‘Colmar du Mortier’). Total RNA was analysed from ‘Joseph Musch’ (tree Q9) after high throughput sequencing. Double-stranded RNA (dsRNA) and virion-associated nucleic acids (VANA) preparation protocols were applied on the other samples individually (dsRNA) or pooled (dsRNA and VANA). After sequencing, the obtained data were analysed with Geneious Prime to identify the viruses present in the sampled trees and to reconstruct their genomes. In addition, two other bioinformatics pipelines were tested on the generated data (Kaiju and Kraken). The nearly complete genome sequence of seven new isolates from several known viruses was reconstructed. All the samples were infected by at least one virus, the most prevalent was ASPV. Interestingly, the detection of Apple rubbery wood virus-1 (ARWV-1), Apple luteovirus-1 (ALV-1) and Apple hammerhead viroid-like RNA (AHVd-like RNA) corresponded to the first detection in Europe. Primer and RT-PCR protocols were designed. The presence of ARWV-1 was detected by RT-PCR, confirming the first detection of this virus in Europe. Further studies need to be carried out to assess the distribution of ARWV-1 within the germplasm collection and to confirm the detection of ALV-1 and AHVd. The analysis of the local prevalence of these viruses will be a first step to evaluate the biological risk they can pose for European production.

Abstract

Many of the world's most important food crops are grown in the tropics and the majority of them are affected with one or another virus or viroid diseases.  Plant virus and sub-viral agents are one of the factors that affect productivity and cause vast economic losses to staple crops across the tropics.  Sustained efforts are being made in universities and research institutions of both state and central facilities, and have resulted in dramatic success in managing some of the most devastating virus diseases.  However, emergence of new viruses and strains of existing viruses, along with changing contexts due to agricultural intensification and climate change resulted in creating new challenges and demanding even greater effort to overcome hurdles to increase agricultural productivity, food availability and economic development. Methods for the detection and identification of viruses and virus-like diseases in plants and vectors play a critical role in plant virus epidemiology and in turn plant virus management.  Advancements in serological and molecular techniques have greatly improved the speed and accuracy of virus and sub-viral pathogen identification.  To keep up with the constant threat of emerging and re-emerging plant viruses, it is necessary to identify, predict and monitor sources of outbreaks at the worldwide level to minimize small infection proportions from becoming devastating pandemics.  Diagnosis of plant virus and sub-viral agents and their  prevention / management is an integral part of agricultural production systems and regulatory frame works that exist in almost all tropical countries.  Plant virus epidemiology provides powerful tools to investigate key factors that contribute to virus epidemics in agricultural crops.  These epidemiological approaches help to guide decisions regarding plant protection strategies.  The dynamics of a particular virus disease epidemic depends on the number of vectors and their activity, sources of virus and vectors, climatic conditions and a complex series of virus - plant - vector interactions.  The importance of epidemiology needs to be realized for the management of virus diseases in an integrated disease management program (IPM) and also for generating information on pest / disease-free areas and for pest risk analysis, which is an obligation for our international trade.  Even though there are number of virus and virus-like disease management measures, whenever individually are used alone, the benefits received are very small and may become infective with time.  On other hand, in an integrated approach, when different ways of virus management measures are combined and used together, there would be effective overall reduction or control of virus and sub-viral diseases.  Integrated virus management strategies are to be comprehensive, effective and should protect farmers from economic hardships due to crop losses because of virus and virus-like diseases.  The virus management strategies developed must be robust and involve minimum extra expenditure.  This book is an excellent latest source of information for those interested in plant virus teaching, research and virus management.  It is also invaluable resource for research workers, educators, students of plant virology, plant pathology, plant breeding, biotechnology, molecular biology.

Abstract

Plant virus and sub-viral agents cause considerable losses in crop production as they are so widely spread.  They are transmitted by means of vegetative propagation of seedlings and also through insect vectors.  They infect field crops, vegetables, cereals, oil seeds, fruit crops and ornamentals.  The virus may enter into plants through seed / planting material or by vectors.  Once the virus is in the field, it multiplies and spreads following definite patterns depending upon the nature of the vector and agro-meteorological conditions. Detection of virus and sub-viral agents at initial stages of infection is critical to reduce economic losses.  For nearly two decades, ELISA and its variants played a major role in large scale virus testing and also in the production of virus-free planting materials.  In recent years nucleic acid - based molecular detection methods such as the amplification of nucleic acids (PCR and its variants), microarrays, rDNA technology, DNA barcoding, DNA biosensors and other improved techniques are playing pivotal role in specific virus testing, identification of new viruses, virus strain differentiation, identification of virus relationships and other biological aspects, as these techniques are specific, sensitive and reproducible.  Nevertheless, integrated management measures have evident benefits and should be fostered and promoted for managing virus and sub-viral diseases for enhancing crop productivity. This book provides the latest valuable overview of the plant virus and virus-like diseases in tropical countries on aspects like introduction about plant viruses, their classification; transmission and diagnostic techniques; the well written chapters are thoroughly up-to-date and amply and clearly illustrated with numerous photographs.  It is a good source of information on plant virus and sub-viral pathogens to all plant virologists, students, faculty, research and quarantine organizations.

Abstract

Viruses are microscopic agents that exist worldwide and are present in humans, animals, plants, and other living organisms in which they can cause devastating diseases. However, the advances of biotechnology and next-generation sequencing technologies have accelerated novel virus discovery, identification, sequencing, and manipulation, showing that they present unique characteristics that place them as valuable tools for a wide variety of biotechnological applications. Many applications of viruses have been used for agricultural purposes, namely concerning plant breeding and plant protection. Nevertheless, it is interesting to mention that plants have also many advantages to be used in vaccine production, such as the low cost and low risks they entail, showing once more the versatility of the use of viruses in biotechnology. Although it will obviously never be ignored that viruses are responsible for devastating diseases, it is clear that the more they are studied, the more possibilities they offer to us. They are now on the front line of the most revolutionizing techniques in several fields, providing advances that would not be possible without their existence. In this book there are presented studies that demonstrate the work developed using viruses in biotechnology. These studies were brought by experts that focus on the development and applications of many viruses in several fields, such as agriculture, the pharmaceutical industry, and medicine.
