Interrelationships of Food Safety and Plant Pathology: The Life Cycle of Human Pathogens on PlantsAnnual Review of Phytopathology - Tập 50 Số 1 - Trang 241-266 - 2012
Jeri D. Barak, Brenda K. Schroeder
Bacterial food-borne pathogens use plants as vectors between animal hosts, all the while following the life cycle script of plant-associated bacteria. Similar to phytobacteria, Salmonella, pathogenic Escherichia coli, and cross-domain pathogens have a foothold in agricultural production areas. The commonality of environmental contamination translates to contact with plants. Because of the...... hiện toàn bộ
PATHOGEN POPULATION GENETICS, EVOLUTIONARY POTENTIAL, AND DURABLE RESISTANCEAnnual Review of Phytopathology - Tập 40 Số 1 - Trang 349-379 - 2002
Bruce A. McDonald, Celeste C. Linde
▪ Abstract We hypothesize that the evolutionary potential of a pathogen population is reflected in its population genetic structure. Pathogen populations with a high evolutionary potential are more likely to overcome genetic resistance than pathogen populations with a low evolutionary potential. We propose a flexible framework to predict the evolutionary potential of pathogen populations...... hiện toàn bộ
The Origins of Plant Pathogens in Agro-EcosystemsAnnual Review of Phytopathology - Tập 46 Số 1 - Trang 75-100 - 2008
Eva H. Stukenbrock, Bruce A. McDonald
Plant pathogens can emerge in agricultural ecosystems through several mechanisms, including host-tracking, host jumps, hybridization and horizontal gene transfer. High-throughput DNA sequencing coupled with new analytical approaches make it possible to differentiate among these mechanisms and to infer the time and place where pathogens first emerged. We present several examples to illustr...... hiện toàn bộ
Molecular Ecology and Emergence of Tropical Plant VirusesAnnual Review of Phytopathology - Tập 44 Số 1 - Trang 235-260 - 2006
D. Fargette, Gnissa Konaté, C. Fauquet, E. Müller, Michel Peterschmitt, J. M. Thresh
Abstract An appreciation of the risks caused by emergent plant viruses is critical in tropical areas that rely heavily on agriculture for subsistence and rural livelihood. Molecular ecology, within 10 years, has unraveled the factors responsible for the emergence of several of the economically most important tropical plant viruses: Rice yellow mottle virus (RYMV), Cassava mosaic geminivi...... hiện toàn bộ
Role of Stomata in Plant Innate Immunity and Foliar Bacterial DiseasesAnnual Review of Phytopathology - Tập 46 Số 1 - Trang 101-122 - 2008
Maeli Melotto, William Underwood, Sheng Yang He
Pathogen entry into host tissue is a critical first step in causing infection. For foliar bacterial plant pathogens, natural surface openings, such as stomata, are important entry sites. Historically, these surface openings have been considered as passive portals of entry for plant pathogenic bacteria. However, recent studies have shown that stomata can play an active role in limiting bac...... hiện toàn bộ
Potyviruses and the Digital RevolutionAnnual Review of Phytopathology - Tập 48 Số 1 - Trang 205-223 - 2010
Adrian Gibbs, Kazusato Ohshima
The potyviruses are one of the two most speciose taxa of plant viruses. Our expanded knowledge of the breadth and depth of their diversity and its origins has depended greatly on the use of computing and the Internet in biological research and is reviewed here. We report a fully supported phylogeny based on gene sequence data for approximately half the named species. The phylogeny shows th...... hiện toàn bộ
SYSTEMIC ACQUIRED RESISTANCEAnnual Review of Phytopathology - Tập 42 Số 1 - Trang 185-209 - 2004
Wendy E. Durrant, Xinnian Dong
▪ Abstract Systemic acquired resistance (SAR) is a mechanism of induced defense that confers long-lasting protection against a broad spectrum of microorganisms. SAR requires the signal molecule salicylic acid (SA) and is associated with accumulation of pathogenesis-related proteins, which are thought to contribute to resistance. Much progress has been made recently in elucidating the mec...... hiện toàn bộ
