Download or read book Pathways of Infection of Phytophthora Ramorum in Rhododendron written by Carrie D. Lewis and published by . This book was released on 2005 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phytophthora ramorum, a plant pathogen, is the cause of sudden oak death and ramorum blight and shoot die-back. It has a wide host range including many native forest species and common nursery plants. The lack of knowledge regarding infection biology of P. ramorum limits our understanding of its ecology and epidemiology. Pathways of infection were investigated in Rhododendron 'Nova Zembla' using tissue culture plantlets and greenhouse-grown container plants planted in artificially-infested potting medium, or inoculated with a zoospore suspension or mycelial plugs. The presence of the pathogen in plant tissue was determined by isolation onto selective medium and PCR analysis. Histological examinations of tissue samples were performed with fluorescence, scanning electron and scanning laser confocal microscopy. Inoculated roots, stems and leaves were examined to identify pathways by which P. ramorum infects and colonizes rhododendrons. Results indicate that roots can be infected by P. ramorum without causing root rot. Below-ground infections arising from artificially infested potting medium resulted in infection of above-ground stems and leaf petioles. P. ramorum was found in the primary xylem of below-ground and above-ground stem tissue. Inoculation of roots with zoospore inoculum resulted in inter- and intracellular penetration of root tissue. Cysts appeared to aggregate at wound sites and near root primoridia. Examination of inoculated leaves revealed that P. ramorum does not require stomata for leaf infection. P. ramorum spread from inoculated leaves into petioles and stems via the vascular tissue (primary xylem). These results indicate that P. ramorum may be present but not cause obvious symptoms in certain plant tissues. This may contribute to difficulties in detection of infected plants, a requirement for limiting the long-distance spread of the disease with infested nursery stock.

Available in PDF, EPUB and Kindle. Book excerpt: Fungal diseases have contributed to death and disability in humans, triggered global wildlife extinctions and population declines, devastated agricultural crops, and altered forest ecosystem dynamics. Despite the extensive influence of fungi on health and economic well-being, the threats posed by emerging fungal pathogens to life on Earth are often underappreciated and poorly understood. On December 14 and 15, 2010, the IOM's Forum on Microbial Threats hosted a public workshop to explore the scientific and policy dimensions associated with the causes and consequences of emerging fungal diseases.

Download or read book Comprehensive and Molecular Phytopathology written by Yuri Dyakov and published by Elsevier. This book was released on 2007-01-09 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a collection of information on successive steps of molecular ‘dialogue’ between plants and pathogens. It additionally presents data that reflects intrinsic logic of plant-parasite interactions. New findings discussed include: host and non-host resistance, specific and nonspecific elicitors, elicitors and suppressors, and plant and animal immunity. This book enables the reader to understand how to promote or prevent disease development, and allows them to systematize their own ideas of plant-pathogen interactions. * Offers a more extensive scope of the problem as compared to other books in the market* Presents data to allow consideration of host-parasite relationships in dynamics and reveals interrelations between pathogenicity and resistance factors* Discusses beneficial plant-microbe interactions and practical aspects of molecular investigations of plant-parasite relationships* Compares historical study of common and specific features of plant immunity with animal immunity
Download or read book Diseases of Woody Ornamentals and Trees in Nurseries written by Ronald Klair Jones and published by American Phytopathological Society. This book was released on 2001 with total page 522 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extension agents from around the country offer practical, informative articles addressing the diseases of crops grown in nurseries. Some introductory pieces address abiotic and biotic causes of disease and eleven general diseases such as Botrytis blight and Verticillium wilt. The diseases to which 64 shade trees, shrubs, ground covers, and subtropical ornamentals are susceptible are then discussed in detail, along with methods for the diseases' control. The remaining 17 articles address aspects of disease management, from an introduction to the management of infectious plant diseases in the nursery to tissue culture of woody plants and regulatory control issues. c.

Download or read book Insects and Diseases of Mediterranean Forest Systems written by Timothy D. Paine and published by Springer. This book was released on 2016-01-06 with total page 888 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insect and disease issues are often specific to the Mediterranean forest systems rather than shared with the temperate forests. In addition to the specific native insects and diseases, the forests are subject to the invasion of exotic species. The forests are also at risk from high degrees of human activity, including changing patterns of forest fires, land management activities, intensive plantation forestry using introduced timber species from other Mediterranean climate zones, and atmospheric deposition. Combined with elements of global climate change that may disproportionately affect Mediterranean climate systems, this creates a number of significant management issues that are unique to the Mediterranean forests. It is our goal that the information contained in this volume will contribute to understanding the unique aspects of Mediterranean forest systems and to protecting these critical resources.
