Book Description
Bacterial canker of tomato is an economically devastating disease with a worldwide distribution caused by the gram-positive pathogen Clavibacter michiganensis. The seedborne pathogen systemically colonizes the tomato xylem, causing unilateral leaflet wilt, stem and petiole cankers, marginal leaf necrosis, and plant death. Splash dispersal of the bacterium onto fruit exteriors causes bird's-eye lesions, which are characterized as necrotic centers surrounded by white halos. The pathogen can colonize developing seeds systemically through the xylem and through penetration of fruit tissues from the exterior. There are no commercially available resistant tomato cultivars, and copper-based bactericides have limited efficacy for controlling the disease once the pathogen is in the xylem. This dissertation describes differences in pathogen colonization of xylem and fruit between tolerant and susceptible Solanum species, demonstrating that C. michiganensis is impeded in systemic and intravascular spread in the xylem, and is capable of causing bird's-eye lesions on wild tomato fruit. The size at which S. lycopersicum fruit inoculated with C. michiganensis and two additional bacterial pathogens begins developing lesions, peaks in susceptibility, and ceases developing lesions was determined in wildtype and ethylene-responsive mutants. Changes in chemical composition of xylem sap from susceptible S. lycopersicum and tolerant S. habrochaites plants during C. michiganensis infection was determined using untargeted metabolomics. Finally, a high-resolution proteome of C. michiganensis pellets and supernatant samples was generated and used to refine the reference genome. Together, these data provide a deeper understanding of C. michiganensis colonization of diverse host tissues, as well as host responses that may contribute to symptom development.

Book Description
Ecology of Root Pathogens discusses the significance of fungi infecting the roots, and emphasizes the significant diseases of roots and their symptoms. This book also names the genera and species of fungi that cause diseases of roots, and classifies and characterizes the root and pathogen interaction in soil. The book describes the behavior of plant pathogenic bacteria, such as Agrobacterium, Corynebacterium, Xanthomonas, Pseudomonas, Erwinia, and Streptomyces. It also explores how plants and plant-produced stimuli affect the associated population of plant parasitic nematodes and how these plant parasitic nematodes affect higher plants in certain ways. In addition, this book discusses the morphology, classification, nomenclature, multiplication and translocation of viruses infecting the plants. It also describes the symptoms of the virus infection in roots. The book includes a discussion on the fundamentals of biological control, which include the pathosystem concept, the behavior of the soil microflora in the soil, the reservoirs for infection, the processes of pathogen decline, and the integrated effects on the decline of the pathogen. This discussion on biological control also presents the natural and artificially induced biological control. This book will be of great value to soil microbiologists and plant pathologists.
