Download or read book Nematode Vectors of Plant Viruses written by F. Lamberti and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although nematodes had long been suspected as vectors of soil borne plant diseases, unequivocal proof of their implication was not forthcoming until 1958 when Professor William Hewitt and his colleagues in California demonstrated experimentally that Xiphinema ~ was the vector of grapevine fanleaf virus. This opened up a new and exciting field in plant pathology and discoveries quickly followed of other nematode species associated with soil-borne diseases of many different crops and in several countries. After the initial enthusiasm of discovering new vectors and new viruses there followed a period of consolidation in which research workers sought answers to tantalising questions about the location of the virus within the nematode, the factors governing the close speci ficity between virus and vector; and more mundane but equally important and compelling questions about life cycles, geographical distribution, host relations, morphology and taxonomy. No other group of nematodes has attracted such a concentrated effort involv ing many different scientific specialisations and yielding so much progress in a relatively short time. The NATO Advanced Study Institute held at Riva dei Tessali, Italy, during 19 May to 2 June, 1974, provided the forum for a critical discussion of all aspects of biology of virus vector nema todes.

Available in PDF, EPUB and Kindle. Book excerpt: Plant viruses cause many of the most important diseases threatening crops worldwide. Over the last quarter of a century, an increasing number of plant viruses have emerged in various parts of the world, especially in the tropics and subtropics. As is generally observed for plant viruses, most of the emerging viruses are transmitted horizontally by biological vectors, mainly insects. Reverse genetics using infectious clones--available for many plant viruses--has been used for identification of viral determinants involved in virus-host and virus-vector interactions. Although many studies have identified a number of factors involved in disease development and transmission, the precise mechanisms are unknown for most of the virus-plant-vector combinations. In most cases, the diverse outcomes resulting from virus-virus interactions are poorly understood. Although significant advances have been made towards understand the mechanisms involved in plant resistance to viruses, we are far from being able to apply this knowledge to protect cultivated plants from the all viral threats.The aim of this Special Issue was to provide a platform for researchers interested in plant virology to share their recent results. To achieve this, we invited the plant virology community to submit research articles, short communications and reviews related to the various aspects of plant virology: ecology, virus-plant host interactions, virus-vector interactions, virus-virus interactions, and control strategies. This issue contains some of the best current research in plant virology.
Download or read book New Viral Vectors for the Expression of Antigens and Antibodies in Plants written by Zun Liu and published by . This book was released on 2009 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants viruses are increasingly being examined as alternative recombinant protein expression systems. Future development of plant virus expression vectors needs to focus on the most important economic hosts, namely cereals and legumes, to develop tools to aid breeding of such hosts and systems for edible vaccine production. Sunn hemp mosaic virus (SHMV) is a tobamovirus, which infects leguminous plants. This work reports on new SHMV-based viral vectors for high yield of target proteins in legumes. In the SHEC vector series, the coat protein gene of SHMV was substituted by a reporter gene. In the SHAC vector series, the coat protein was substituted by a reporter gene and the coat protein gene from another tobamovirus, tobacco mild green mosaic virus (TMGMV). Co-agroinoculation of SHEC/GFP with an RNA silencing suppressor resulted in high levels of local GFP expression by 3 days post inoculation. Co-agroinoculation with SHAC/GFP led to systemic fluorescence in 12-19 dpi. Foxtail mosaic virus (FoMV) is a species of the group Potexvirus, which infects cereal plants. A new viral vector series named FECT was constructed by eliminating the triple gene block and coat protein genes, reducing the viral genome by 29%. Interestingly, agroinoculation of the vector alone results in only slight transient expression, whereas co-inoculation with silencing suppressor genes allows for GFP expression of 40% total soluble protein. Full-sized HC and LC components of an anti-langerin IgG, each carried by a separate FECT vector, expressed and folded into immunologically functional antibody upon co-inoculation. This may prove a useful and environmentally safe vector for both transient expression and perhaps transgenic plants. Mountain cedar (Juniperus ashei) pollen causes severe allergies in Texas and the central USA. Jun a 1 is the dominant allergen protein of mountain cedar pollen and would be a good allergen vaccine candidate. Recombinant Jun a 1 was expressed in Nicotiana benthamiana using an agroinoculation-compatible tobacco mosaic virus vector and isolated in good quantity from the apoplast by vacuum infiltration (100 [mu]g/g leaf material). The recombinant protein samples were characterized. Pectate lyase activity was detected from plant extracts, suggesting the cause of severe necrotic reaction in plants.

Download or read book The Application of Viruses to Biotechnology written by Carla Varanda and published by Mdpi AG. This book was released on 2021-12-21 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Plant Virus and Viroid Diseases in the Tropics written by K. Subramanya Sastry and published by Springer Science & Business Media. This book was released on 2013-06-26 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant virus and sub-viral pathogens pose severe constraints to the production of wide range of economically important crops worldwide. The crops raised both through true seed and vegetative propagated materials are affected with number of virus and virus-like diseases. The virus may enter into plants through seed planting materials 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. Disease free crops and plants are great economic and social importance in feeding the world's population. 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.

Download or read book Virus Induced Gene Silencing written by Annette Becker and published by Humana Press. This book was released on 2013-02-06 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants are amazing organisms to study, some are important sources for pharmaceuticals, and others can help to elucidate molecular mechanisms required for a plant’s development and its interactions with the biotic or abiotic environment. Functional genomics is vastly lagging behind the speed of genome sequencing as high-throughput gene function assays are difficult to design, specifically for non-model plants. Bioinformatics tools are useful for gene identification and annotation but are of limited value for predictions concerning gene functions as gene functions are uncovered best by experimental approaches. Virus-Induced-Gene-Silencing (VIGS) is an easy to use, fast, and reliable method to achieve down regulation of target gene expression. Virus-Induced Gene Silencing: Methods and Protocols provides detailed protocols for VIGS experiments in several plant species including model and non-model plants. Also included in this book are recently developed protocols for VIGS-derived microRNA production in the plant or protein over expression, as well as chapters devoted to summarizing the molecular mechanisms of VIGS action and the vector systems developed so far. Written in the successful Methods in Molecular BiologyTM series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and easily accessible, Virus-Induced Gene Silencing: Methods and Protocols serves as a valuable resource for researchers from diverse fields of plant biology interested in experimental approaches to analyzing gene functions.
