Download or read book Complexity of Potyvirus Resistance in Maize written by Timothy John Gustafson and published by . This book was released on 2017 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: In maize (Zea mays L.), sugarcane mosaic virus (SCMV) and maize dwarf mosaic virus (MDMV) are important pathogens causing yield losses worldwide. Resistance to SCMV and MDMV in maize has been found from many sources, and much of the genetic contribution to resistance is associated with two loci, Scmv1/Mdm1 and Scmv2. However, these loci do not account for all genetic variation, and other loci add to the complexity of resistance by modifying the efficacy of Scmv1/Mdm1 and Scmv2. This study utilized a diverse maize panel, the Wisconsin Diversity Panel, consisting of over 600 inbreds adapted to a northern U.S.A. Corn Belt environment to evaluate variation for SCMV and MDMV resistance. In a genome-wide association study (GWAS) of the panel inoculated with SCMV in an open field trial at the three-leaf growth stage, Scmv1 accounted for much of the genetic variation, especially early after inoculation. Scmv2 and other loci contributed to resistance several weeks after inoculation. A large presence/absence variation encompasses Scmv1, and 44 percent of inbreds contained the absence version and were fully susceptible to SCMV. Inoculation with SCMV was subsequently performed at two different growth stages to evaluate the efficacy of Scmv1. Symptom development was greater with inoculation at the three-leaf stage than at the six-leaf stage, but some inbreds became fully symptomatic after 35 days regardless of growth stage at inoculation. Greenhouse inoculation was conducted to evaluate genetic differences in resistance to SCMV and MDMV. GWAS based on the greenhouse study determined that Scmv1/Mdm1 contributed a greater amount to resistance for both SCMV and MDMV in the greenhouse compared to the SCMV field study. Finally, genomic selection (GS) for SCMV resistance was coupled with GS for northern corn leaf blight, Goss's wilt and common rust. Prediction accuracy for SCMV resistance based on cross-validation was as high as 0.75, and prediction accuracies for other diseases ranged from 0.45 to 0.69. GS prediction accuracies for multi-disease selection based on a selection index varied from 0.39 to 0.66 suggesting index-based GS could be effective for selection of inbreds resistant to all four diseases.

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.
Download or read book Potyvirus Taxonomy written by Ortus W. Barnett and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Biotic Stress Resistance in Millets written by I. K. Das and published by Academic Press. This book was released on 2016-08-03 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biotic Stress Resistance in Millets presents an important guide to the disease and pest-related challenges of this vital food crop. Biotic stresses are one of the major constraints for millet production, but newly emerging and forward-thinking problems with disease and insect pests are likely to increase as a result of changing weather, making this an imperative book on best practices. Current strategies are mainly through the development of resistant cultivars, as the use of chemicals is cost-prohibitive to many of those producing millet in developing countries where it is of most value as a food source. This book explores non-chemical focused options for improving plant resistance and protecting crop yield. This single-volume reference will be important for researchers, teachers and students in the disciplines of Agricultural Entomology, Plant protection, Resistance Plant Breeding and Biotechnological pest management. Establishes basic concepts of host resistance providing foundational insight Synthesizes past biotic stress resistance research with the latest findings to orient research for future strategies for plant protection Focuses exclusively on host plant resistance on all major diseases and pests of millets Presents data and strategies that are globally applicable as millets gain importance as a health food

Download or read book Durability of Disease Resistance written by Th. Jacobs and published by Springer Science & Business Media. This book was released on 2012-02-02 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: From February 24 -28, 1992 an international symposium on Durability of Disease Resistance was held at the International Agricultural Centre in Wageningen, the Netherlands. The symposium, organized by the Department of Plant Breeding of Wageningen Agricultural University and the Centre for Plant Breeding and Repro duction Research, CPRO-DLO, was part of the DGIS funded programme Durable Resistance in Developing Countries. Without any form of prevention or protection nearly all crops will be seriously or even severely damaged by a range of pathogens. In modern agriculture man has been able to control many if not most pathogens using i) pesticides, ii) phyto sanitary methods such as control of seed and plant material in order to start a crop disease free, iii) agronomic measures such as crop rotation, iv) disease resis tance or combinations of these measures. Over the years the use of pesticides has increased enormously and so did the pro blems associated with pesticide use, such as environmental pollution and building of resistance and tolerance to these pesticides in the pathogens. The use of resis tance too increased strongly over the years and here too problems arose.
