Genetics of Resistance to Potyviruses Impacting Snap Bean (Phaseolus Vulgaris L.) Production in the United States
Author: John Patrick Hart

ISBN:
Category :
Languages : en
Pages : 188
Book Description
Snap bean (Phaseolus vulgaris L.) is an important crop to diversified vegetable production in the Great Lakes Region of the United States, but an aphid-transmitted virus disease complex threatens sustainable production. The component viruses include the potyviruses Clover yellow vein virus (ClYVV) and Bean yellow mosaic virus (BYMV) that are acquired and transmitted rapidly by dispersing aphid vectors. This situation necessitates the identification, introgression, and deployment of plant virus resistance alleles to achieve effective and ecologically sensitive control. Genetic variation for resistance to ClYVV was characterized at the phenotypic and molecular genetic levels. The relationship of three previously putative independent resistance alleles, cyv, desc, and bc-3 was resolved into an allelic series at the Bc-3 locus where the strain and species-specific resistance spectrum was allele specific. Given previous advances, this pathosystem presented an immediate candidate gene, P. vulgaris eIF4E (PveIF4E), as the molecular basis for resistance. A complete association between specific non-synonymous single nucleotide polymorphisms (SNPs) and virus resistance led to the identification of the putative molecular determinants for resistance to ClYVV and Bean common mosaic necrosis virus (BCMNV) strain NL 3 D. PveIF4E allele specific assays were developed for rapid introgression of bc-3 and the novel bc-32 allele into bean breeding programs. Phenotypic evaluation and the allele specific assays were used to further characterize ClYVV resistance in a large and representative sample of common bean genetic diversity. The result was the identification of novel ClYVV resistance in all major market classes, and the validation of the use of the assays for allele mining in germplasm collections. These efforts also lead to the phenotypic identification of ClYVV resistance alleles at independent loci, and established a model for resistance that now includes By-2 and the bc-u, bc-22 combination. The novel and highly efficient genotyping-by-sequencing (GBS) method was adapted to common bean and used to map the position of the By-2 allele for resistance to BYMV and ClYVV. By-2 was mapped to within a 974k kb region on the distal portion of chromosome 2. This effort generated genomic resources for fine mapping and assays that were also validated for marker-assisted selection.

Plant Resistance to Viruses
Author: David Evered
Publisher: John Wiley & Sons
ISBN: 0470513578
Category : Science
Languages : en
Pages : 226
Book Description
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.

Potyvirus Taxonomy
Author: Ortus W. Barnett
Publisher: Springer Science & Business Media
ISBN: 3709169208
Category : Science
Languages : en
Pages : 431
Book Description
A number of economically important diseases are caused by potyviruses, the largest group of plant viruses. Many of these diseases are distributed worldwide. The development of effective control strategies against viruses is dependent on the availability of reliable methods of identification and detection. To date this has not seemed possible for the potyvirus group, because of its size, complexity, and immense variation. This book brings together the collaborative efforts of exports in the field. It summarizes characteristics of potyviruses which relate to their taxonomy and points to areas which require consideration before an international consensus can be reached. Main topics dealt with in detail are: serological relationships, nucleic acid sequence information, biological properties, and specific problems with several virus subgroups or pairs of viruses.

Natural and Engineered Resistance to Plant Viruses
Author:
Publisher: Academic Press
ISBN: 0080923089
Category : Science
Languages : en
Pages : 280
Book Description
Viruses are a huge threat to agriculture. In the past, viruses used to be controlled using conventional methods, such as crop rotation and destruction of the infected plants, but now there are more novel ways to control them. This volume focuses on topics that must be better understood in order to foster future developments in basic and applied plant virology. These range from virus epidemiology and virus/host co-evolution and the control of vector-mediated transmission through to systems biology investigations of virus-cell interactions. Other chapters cover the current status of signalling in natural resistance and the potential for a revival in the use of cross-protection, as well as future opportunities for the deployment of the under-utilized but highly effective crop protection strategy of pathogen-derived resistance. Contributions from leading authorities Informs and updates on all the latest developments in the field
