Book excerpt: Bacterial pathogens are significant biotic factors of wheat, a globally important source of carbohydrates. The diseases caused by these pathogens are reported to reduce annual wheat production by about 10% and up to 40% in severe infections occurring early in the growth period. This chapter presents current information on the symptoms, distribution, identification, and taxonomy of key bacterial pathogens of wheat with a focus on the seed-borne bacterium, Xanthomonas translucens pv. undulosa, the causative agent of the leaf streak and black chaff disease. Other wheat-pathogenic bacterial pathogens addressed in the chapter are Pseudomonas syringae pv. syringae, the causal agent of bacterial leaf blight; P. syringae pv. atrofaciens that cause the basal glume rot; Pseudomonas fuscovaginae, the causal agent of the bacterial brown sheath; Erwinia rhapontici, the causal agent of the pink seed of wheat; Pseudomonas cichorii, the causative agent of wheat stem melanosis; Clavibacter tessellarius is responsible for the bacterial mosaic of wheat as well as other minor bacterial pathogens. Finally, the chapter proposed the use of genome-based tools for the accurate identification and classification of bacterial pathogens of wheat.

Available in PDF, EPUB and Kindle. Book excerpt: Septoria leaf blotch has been the major disease of wheat in Britain and much of the rest of Europe. It has been reported that the disease causes serious yield losses to range from 31 to 53%. Mycosphaerella graminicola (anamorph: Septoria tritici) is the pathogen which causes Septoria leaf blotch. The disease can be controlled by various methods such as cultural practices, chemical control, using resistant varieties and biological control. In plant pathology, the term biological control leads to the introduction of microbial antagonists or host specific pathogens to suppress diseases and populations of one or more plant pathogens. This study investigated the microbial community on and within wheat leaves which can suppress Septoria leaf blotch by reducing the inoculum level of the causative pathogen M. graminicola. Plate count and DGGE analysis techniques were used to assess the microbial community. The changes in the microbial populations of healthy, senescent and M. graminicola infected i.e. diseased wheat leaves were investigated in vitro on agar plates using plate colony count method. It was found that method was successful in assessing both bacterial and fungal population sizes showing distinct colonies. DGGE is a rapid method which can analyze large number of samples simultaneously. The bands appearing in DGGE profile represent different species present in the microbial population. The DGGE technique was successfully used in this study to assess bacterial community. Bioinformatics tools have also played a vital role in this study for identifying bacterial and fungal species. A total of five bacterial species and five fungal species were identified by bioinformatics tools. The antagonistic abilities of identified bacterial and fungal species were tested against a Septoria isolate in vitro on dual culture PDA plates. Four microorganisms (Fusarium sp., Verticillium sp., Penicillium sp., Sporobolomyces sp. and Microbotryum sp.) in the dual cultures vary in their colony length, width, ratio of length and width and distance bwtween them. But after statistical analysis all the values are insignificant observations of dual culture plates indicated that the microorganisms might inhibit Septoria by competing for space. These microorganisms after testing might be good candidates for further in vivo testing of Septoria inhibition. A thorough knowledge of wheat leaf microbial communities is required for further use of biocontrol in the future.

Book excerpt: Wheat Blast provides systematic and practical information on wheat blast pathology, summarises research progress and discusses future perspectives based on current understanding of the existing issues. The book explores advance technologies that may help in deciding the path for future research and development for better strategies and techniques to manage the wheat blast disease. It equips readers with basic and applied understanding on the identification of disease, its distribution and chances of further spread in new areas, its potential to cause yield losses to wheat, the conditions that favour disease development, disease prediction modelling, resistance breeding methods and management strategies against wheat blast. Features: Provides comprehensive information on wheat blast pathogen and its management under a single umbrella Covers disease identification and diagnostics which will be helpful to check introduction in new areas Discusses methods and protocol to study the different aspects of the disease such as diagnostics, variability, resistance screening, epiphytotic creation etc. Gives deep insight on the past, present and future outlook of wheat blast research progress This book’s chapters are contributed by experts and pioneers in their respective fields and it provides comprehensive insight with updated findings on wheat blast research. It serves as a valuable reference for researchers, policy makers, students, teachers, farmers, seed growers, traders, and other stakeholders dealing with wheat.

Download or read book Seed Endophytes written by Satish Kumar Verma and published by Springer. This book was released on 2019-04-05 with total page 507 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the importance and roles of seed microbiomes in sustainable agriculture by exploring the diversity of microbes vectored on and within seeds of both cultivated and non-cultivated plants. It provides essential insights into how seeds can be adapted to enhance microbiome vectoring, how damaged seed microbiomes can be assembled again and how seed microbiomes can be conserved. Plant seeds carry not only embryos and nutrients to fuel early seedling growth, but also microbes that modulate development, soil nutrient acquisition, and defense against pathogens and other stressors. Many of these microbes (bacteria and fungi) become endophytic, entering into the tissues of plants, and typically exist within plants without inducing negative effects. Although they have been reported in all plants examined to date, the extent to which plants rely on seed vectored microbiomes to enhance seedling competitiveness and survival is largely unappreciated. How microbes function to increase the fitness of seedlings is also little understood. The book is a unique and important resource for researchers and students in microbial ecology and biotechnology. Further, it appeals to applied academic and industrial agriculturists interested in increasing crop health and yield.
