Pepper Virome: Molecular Biology, Diagnostics and Management presents detailed information about the plant viruses that infect pepper worldwide, providing crucial insights for both the scientific community and producers. Understanding the nature of the viruses, their transmission methods and possible sources of resistance in order to minimize the yield losses as well as to reduce the spread of these viruses to new locations or countries is of global importance.Pepper is an important commodity worldwide. It is cultivated for both fresh produce and for processing industry as a spice. However, various diseases affect pepper production and cause significant yield losses in pepper yield. The increasing outbreaks of virus species infecting Capsicum spp. have become a major problem for growers. A combination of factors, including expansion and intensification of pepper cultivation, availability of volunteer hosts, abundance of insect vectors and climate change have all contributed to the issue. Pepper Virome provides in-depth information on both the viruses infecting peppers, and eco-friendly management measures to decrease the rate of spread of viruses. Addressing the need for increased international collaboration and exchange of pepper germplasm, these insights will also facilitate the selection and breeding for improved Capsicum spp. adapted to local conditions and uses. Focuses on symptomatology, transmission, and epidemiology of pepper viruses Reveals the impact on host, yield, and virus-vector interactions Evaluates management strategies against viruses and how they have evolved

Viral Diseases of Field and Horticultural Crops details the fundamental and applied aspects of the viral diseases of field and horticultural crops. The book opens with a historical introduction to plant virology, important plant virologists, and landmarks. It continues with systematic coverage of viral diseases, their economic significance, disease symptoms, host range, mode of transmission, diagnostic techniques, geographic distribution, epidemiology, yield losses, and control and management of the disease. Contributions from an international group of virologists with a wide range of academic, research, professional, and specialized backgrounds in plant virology makes Viral Diseases of Field and Horticultural Crops a comprehensive and must-have resource for those engaged in the study and research of plant virology, microbiology, and plant pathology particularly viral diseases and their impact on field and horticultural crops. Provides virus characterization according to the disease pattern and symptoms they cause Covers viral diseases of cereals, oil seeds, legumes, commercial crops, spices and condiments, medicinal and aromatic crops, forage crops, vegetable crops, fruit crops, tree nuts, among others Discusses advances like applications in nanotechnology, molecular techniques for the detection and characterization of plant viruses, and the development of technologies for detecting plant viruses

In this study, tomato and pepper populations were phenotypically and genotypically characterized to identify cucumber mosaic virus (CMV) resistant lines and determine the genetic control of resistance. Populations of both crops and their resistant and susceptible parents were mechanically inoculated with CMV. Plants were evaluated visually and by enzyme-linked immunosorbent assay (ELISA). Since virus was detected only in inoculated leaves but was not usually present in uninoculated leaves of symptomless plants, CMV resistance appeared to be true resistance not immunity. According to phenotypic analysis of F2 tomato population, it was hypothesized that two dominant genes were controlling resistance as the plants fit a 9:7 (resistant:susceptible) segregation ratio as determined by Chi square goodness-of-fit analysis. In order to perform quantitiative trait locus (QTL) analysis, molecular markers were surveyed for polymorphism using the two parents of the tomato population, L. esculentum and L. hirsutum LA1223. According to QTL analysis (using 107 polymorphic markers), 11 genomic regions were linked to CMV resistance. For seven loci, resistance alleles were coming from the L. hirsutum parent as expected. However, for four loci, resistance was associated with alleles from the CMV susceptible parent, L. esculentum. These results show that the genetic potential for resistance cannot be determined by only looking at the phenotype of the two parents. As a result of this work, developing elite lines or transferring resistance genes into cultivated species by marker assisted selection will be easier.
