This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Beet curly top virus (BCTV), transmitted by the beet leafhopper (Circulifer tenellus), is the causal agent of curly top disease. The disease can cause substantial yield losses in processing tomato production in California, such as in the major outbreak in 2013. In this study, a loop-mediated isothermal amplification (LAMP) assay was developed to rapidly and specifically detect BCTV in infected leaf tissue and viruliferous leafhoppers. The LAMP primer set, ID1R4, was designed from a conserved region of the BCTV genome identified in 67 isolates. A master mix containing phenol red was used that allows visual identification of a positive (BCTV) detection due to a red to yellow color change in the LAMP assay following 40 min incubation at 65C. When used in this LAMP assay, the ID1R4 primer set mediated detection of five of the six BCTV strains tested, including the major strains that are associated with curly top disease of processing tomatoes in California. Compared with a qPCR test developed for BCTV in this study, the LAMP assay was 10-fold less sensitive for the detection of BCTV DNA in extracts prepared from infected tomato leaf tissue. A commercially available buffer (GEB2) was identified that allowed for rapid preparation of sap from infected leaves that could be used as a template for detection of BCTV in the LAMP assay. Extracts prepared from beet leafhoppers by grinding in sterile water and STE buffer were suitable for the detection of BCTV DNA in the LAMP assay. A tomato line, Line 20 #12, with resistance to BCTV, and a susceptible control line, were infected with BCTV-Svr-Cfh (US-SVR-Cfh) by agroinoculation and compared in terms of time and intensity of detection of the virus in the LAMP assays. Curly top symptoms were considerably less severe in the resistant line 36 days post inoculation (dpi); however, in LAMP assays, viral DNA was detected in leaves of the resistant and susceptible lines beginning at 7 dpi and the intensity of the color change was similar throughout the course of the experiment. We conclude that the LAMP assay developed for detection of BCTV-infected plants and viruliferous beet leafhoppers in this study is rapid and simple when compared to existing qPCR, PCR, and ELISA methods, and can be a useful tool for routine detection and improved disease management.

Book excerpt: 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

Available in PDF, EPUB and Kindle. Book excerpt: Along the undisturbed shores, especially of the Mediterranean Sea and the European North Atlantic Ocean, is a quite widespread plant called Beta maritima by botanists, or more commonly sea beet. Nothing, for the inexperienced observer's eye, distinguishes it from surrounding wild vegetation. Despite its inconspicuous and nearly invisible flowers, the plant has had and will have invaluable economic and scientific importance. Indeed, according to Linnè, it is considered "the progenitor of the beet crops possibly born from Beta maritima in some foreign country". Recent molecular research confirmed this lineage. Selection applied after domestication has created many cultivated types with different destinations. The wild plant always has been harvested and used both for food and as a medicinal herb. Sea beet crosses easily with the cultivated types. This facilitates the transmission of genetic traits lost during domestication, which selection processes aimed only at features immediately useful to farmers and consumers may have depleted. Indeed, as with several crop wild relatives, Beta maritima has been successfully used to improve cultivated beet’s genetic resistances against many diseases and pests. In fact, sugar beet cultivation currently would be impossible in many countries without the recovery of traits preserved in the wild germplasm. Dr. Enrico Biancardi graduated from Bologna University. From 1977 until 2009, he was involved in sugar beet breeding activity by the Istituto Sperimentale per le Colture Industriali (ISCI) formerly Stazione Sperimentale di Bieticoltura (Rovigo, Italy), where he released rhizomania and cercospora resistant germplasm and collected seeds of Mediterranean sea beet populations as a genetic resource for breeding and ex situ conservation. Retired since 2009, he still collaborates with several working breeders, in particular, at the USDA Agricultural Research Stations, at the Chinese Academy of Agricultural Science (CAAS), and at the Athens University (AUA). He has edited books, books chapters and authored more than 150 papers. Dr. Lee Panella is a plant breeder and geneticist with the USDA-ARS at Fort Collins, Colorado. He earned his B.S. in Crop and Soil Science from Michigan State University, an M.S. in Plant Breeding from Texas A&M University, and a Ph.D. in genetics from the University of California at Davis. His research focus is developing disease resistant germplasm using sugar beet wild relatives. He is chairman of the USDA-ARS Sugar Beet Crop Germplasm Committee and has collected and worked extensively with sea beet. Dr. Robert T. Lewellen was raised on a ranch in Eastern Oregon and obtained a B.S. in Crop Science from Oregon State University followed by a Ph.D. from Montana State University in Genetics. From 1966 to 2008 he was a research geneticist for the USDA-ARS at Salinas, California, where he studied the genetics of sugar beet and as a plant breeder, often used sea beet as a genetic source to produce many pest and disease resistant sugar beet germplasm and parental lines, while authoring more than 100 publications.
