Book Synopsis Genome Characterization of Soil-Borne Wheat Mosaic Virus Variants by : Mohammad Reza Mansournia
Download or read book Genome Characterization of Soil-Borne Wheat Mosaic Virus Variants written by Mohammad Reza Mansournia and published by LAP Lambert Academic Publishing. This book was released on 2012-04 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil-borne wheat mosaic virus (SBWMV), the type species of the genus Furovirus, contains a bipartite positive-stranded RNA genome (RNA1 and RNA2) encapsidated in separate rod-shaped particles. The vector that transmits this virus in soil is a plasmodiophoraceous protozoan, Polymyxa graminis. The optimum temperature for the propagation of this virus is 17°C, and systemically infected plants can recover from the virus if the temperature increases. The inoculation of infectious in vitro transcripts of RNA1 and RNA2 into barley mesophyll protoplasts showed that the CP most abundantly accumulated at 17°C, but was undetectable at 25°C (Ohsato et al., 2003), suggesting that replication of the virus is temperature sensitive. Here, the mutations occurred in the MP gene of the variants that could propagate under higher temperatures (25°C) were examined. It is suggested that these mutations are involved in changing of MP conformation/activity to make virus adapted to the new condition (higher temperature) for cell-to-cell and long-distance movement.

This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wheat viruses including Wheat streak mosaic virus (WSMV), Triticum mosaic virus (TriMV), High Plains wheat mosaic emaravirus (HPWMoV), and Barley yellow dwarf virus (BYDV) cost substantial losses in crop yields annually. Although there have been extensive studies conducted on known wheat viruses, currently, there is limited knowledge about all viral components associated with wheat (Triticum aestivum L.) including potential novel viruses. Wheat streak mosaic (WSM), a disease of cereals and grasses, costs Kansas farmers millions in yield losses. Although WSMV is considered as the main causal agent of WSM, TriMV and HPWMoV have also been reported in mixed infections. While resistant varieties are utilized to minimize the effects of the disease, genetic variation in associated viruses increases the emergence of potential resistance-breaking isolates. Currently, little is known about the genetic composition of populations of WSM-associated viruses in the field. This study first aims to analyze the genetic variation and characterize the evolutionary mechanism(s) applied by WSM-associated viruses in the field using complete genomes sequences, and also to determine and characterize all viral populations associated with wheat. Field collections of 24 WSM-like symptomatic and asymptomatic wheat samples were used for total RNA deep sequencing, along with 5 historic WSMV samples for the evolutionary studies. Through bioinformatics analysis, sequences were mapped to available reference genomes and de novo assembled to identify new viruses. Results of the 2019 field survey showed WSMV as the predominant virus followed by mixed infections of WSMV+TriMV. Recombination was observed to be a major evolutionary force for WSMV but not for TriMV isolates. Phylogenetic analyses based on the obtained full genome sequences demonstrated that, unlike other isolates from the United States, Kansas isolates are widely distributed in sub-clades. Moreover, the phylogenetic studies suggested that TriMV field isolates may be under selection pressure to introduce genetic variations due to the use of resistant varieties in the fields. The full genome sequence of a new Kansas HPWMoV isolate was reported here. In addition to known wheat viruses, viral sequences sharing significantly low (

Book Synopsis Plant Resistance to Viruses by : David Evered
Download or read book Plant Resistance to Viruses written by David Evered and published by John Wiley & Sons. This book was released on 2008-04-30 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concern about the environmental consequences of the widespread use of pesticides has increased, and evidence of pesticide-resistant virus vectors have continued to emerge. This volume presents a timely survey of the mechanisms of plant resistance and examines current developments in breeding for resistance, with particular emphasis on advances in genetic engineering which allow for the incorporation of viral genetic material into plants. Discusses the mechanisms of innate resistance in strains of tobacco, tomato, and cowpea; various aspects of induced resistance, including the characterization and roles of the pathogenesis-related proteins; antiviral substances and their comparison with interferon; and cross-protection between plant virus strains. Also presents several papers which evaluate the status of genetic engineering as it relates to breeding resistant plants. Among these are discussions of the potential use of plant viruses as gene vectors, gene coding for viral coat protein, satellite RNA, and antisense RNA, and practical issues such as the durability of resistant crop plants in the field.

Book Synopsis Grapevine Viruses: Molecular Biology, Diagnostics and Management by : Baozhong Meng
Download or read book Grapevine Viruses: Molecular Biology, Diagnostics and Management written by Baozhong Meng and published by Springer. This book was released on 2017-07-05 with total page 688 pages. Available in PDF, EPUB and Kindle. Book excerpt: The domestication of grapes dates back five thousand years ago and has spread to nearly all continents. In recent years, grape acreage has increased dramatically in new regions, including the United States of America, Chile, Asia (China and India), and Turkey. A major limiting factor to the sustained production of premium grapes and wines is infections by viruses. The advent of powerful molecular and metagenomics technologies, such as molecular cloning and next generation sequencing, allowed the discovery of new viruses from grapes. To date, grapevine is susceptible to 64 viruses that belong to highly diverse taxonomic groups. The most damaging diseases include: (1) infectious degeneration; (2) leafroll disease complex; and (3) rugose wood complex. Recently, two new disease syndromes have been recognized: Syrah decline and red blotch. Losses due to fanleaf degeneration are estimated at $1 billion annually in France alone. Other diseases including leafroll, rugose wood, Syrah de cline and red blotch can result in total crop loss several years post-infection. This situation is further exacerbated by mixed infections with multiple viruses and other biotic as well as adverse abiotic environmental conditions, such as drought and winter damage, causing even greater destruction. The book builds upon the last handbook (written over twenty years ago) on the part of diagnostics and extensively expands its scope by inclusion of molecular biology aspects of select viruses that are widespread and economically most important. This includes most current information on the biology, transmission, genome replication, transcription, subcellular localization, as well as virus-host interactions. It also touches on several novel areas of scientific inquiry. It also contains suggested directions for future research in the field of grapevine virology.
