A retrospective of an unconventionally trained plant pathologist: plant diseases to molecular plant pathology.

Plant pathology evolved from its mycology-oriented origins into a science dealing with biochemical mechanisms of diseases, along with enhanced crop production through disease control. This retrospective describes first my personal experience from my introduction to plant pathology, to the establishment of the concept of accessibility as a model pertaining to genetically defined basic compatibility induced by pathogens. I then refer to the development of molecular plant pathology from physiological and biochemical plant pathology fostered by the growth in recombinant technology in the second half of the past century. This progress was best reflected by the U.S.-Japan Seminar Series held at 4-5-year intervals from 1966 to 2003 and documented by publications in major journals of our discipline. These seminars emphasized that progress in science has always been supported by the invention of novel techniques and that knowledge integrated from modern genomics and subsequent proteomics should contribute to the progress of basic life sciences and, more importantly, to the elaboration of rational measures for disease control.

Legacy for the Millennium: A Century of Progress in Plant Pathology.

Plant pathology came of age at the turn of this century and we can be proud of the many significant contributions it has made to fundamental research as well as to service to growers. The twenty-first century will present our profession with dramatic challenges to meet the demands for increased food, fiber, and fuel production from a declining agricultural base. This can be accomplished only if plant pathology retains its integrity as a profession and remains abreast of advancements in the fields of biotechnology and communications.

PLANT PATHOLOGY: a discipline at a crossroads.

The Department of Plant Pathology at the University of California at Berkeley was destroyed as a consequence of a contentious reorganization. The circumstances that led to the reorganization provide some insight into the challenges facing the discipline of plant pathology. The underlying basis for plant pathology as a science is to address problems of plant disease. This requires a balance between disciplinary and problem-solving research and a continuum from achieving fundamental advances in knowledge to the development and implementation of problem-solving approaches. Changes in colleges and universities have placed extreme stress on this essential structure. The dilemma that must be addressed is how to reestablish the problem-solving continuum where it has been broken and strengthen it where it has been weakened. Plants are essential for life, and they will always be affected by disease. The understanding and management of these diseases is the responsibility and the challenge of plant pathology today and in the future.

Innovations in teaching plant pathology.

The teaching environment for plant pathology is changing in both positive and negative ways. Teaching expectations are increasing and resources are decreasing, but recent educational research and instructional technology offer new approaches to meet these challenges. Plant pathologists are teaching courses that may attract new students to the discipline or at least improve agricultural awareness. The Internet offers rapid access to information and images for both students and instructors. Instructional technology provides new tools for classroom presentations, communication with students, reaching new audiences, and distance learning, but using these new tools to enhance learning requires skilled and creative instructors. In the past, many plant pathology instructors worked in relative isolation, but new communication technologies and publishing opportunities for teaching scholarship should improve the sharing of instructional resources and methods.

One foot in the furrow: linkages between agriculture, plant pathology, and public health.

Plant pathology is a field of biology that focuses on understanding the nature of disease in plants as well as on more practical aspects of preventing and controlling plant diseases in crop plants that are important to agriculture. Throughout history, plant diseases have had significant effects on human health and welfare. Several examples, in both historical and contemporary contexts, are presented in this review to show how plant pathogens, biotechnology, and farming practices have affected public health. Specific topics illustrating clear linkages between agriculture and human health include allergens in the environment, food-safety and agricultural practices, mycotoxigenic fungi, agrobioterrorism, and the biological control of plant diseases. The further argument is made that in order to monitor and ensure that good health and safety practices are maintained from "farm to fork," public health specialists may benefit from the resources and expertise of agricultural scientists.

Tropical plant pathology: at home and abroad.

I first describe my introduction to plant pathology and early experiences with employment, the environment, diseases, pests, and various plant pathologists. Then I recount a decade of stimulating studies at the University of Minnesota and the route I followed to a career in international agriculture with the Rockefeller Foundation in Colombia and later at Cornell University. My appreciation for and knowledge of traditional farmers and sustainable agriculture occurred as a slow awakening. Comments are made regarding problems, principles, and satisfactions associated with the improvement of efforts to aid food production in developing countries. My curious love affair with root and tuber crops, especially cassava, is explained and readily defended. My favorite pathogens, Phytophthora infestans and Ralstonia solanacearum, among others, are considered. The pleasures and satisfactions of teaching, writing, and sabbatical leaves are related. Finally, thoughts on the balance between basic and applied research in plant pathology are offered with significant nervousness about the future of our discipline.

A Century of Plant Pathology: A Retrospective View on Understanding Host-Parasite Interactions.

▪ Abstract The twentieth century has been productive for the science of plant pathology and the field of host-parasite interactions-both in understanding how pathogens and plant defense work and in developing more effective means of disease control. Early in the twentieth century, plant pathology adopted a philosophy that encouraged basic scientific investigation of pathogens and disease defense. That philosophy led to the strategy of developing disease-resistant plants as a prima facie disease-control measure-and in the process saved billions of dollars and avoided the use of tons of pesticides. Plant pathology rapidly adopted molecular cloning and its spin-off technologies, and these have fueled major advances in our basic understanding of plant diseases. This knowledge and the development of efficient technologies for producing transgenic plants convey optimism that plant diseases will be more efficiently controlled in the twenty-first century.

E.M. Freeman: early research on cereal diseases and the rise of plant pathology at the University of Minnesota.

E.M. Freeman's role in early cereal disease research and the beginning of plant pathology at the University of Minnesota has been overshadowed largely by the enormous prestige of his student, E.C. Stakman. During the first decade of the twentieth century, Freeman was responsible for the transferral from Europe to the United States and the subsequent nurturing of important conceptual and technical developments in the area of cereal disease pathology. Under Freeman's leadership, these ideas would come to shape the direction of plant pathology research at the University of Minnesota for decades to follow.

Kenneth Frank Baker--pioneer leader in plant pathology.

Kenneth F. Baker (1908-1996) made major contributions to understanding diseases of ornamental plants, seed pathology, soil-borne plant pathogens, biological control, and history of plant pathology. His work set the stage for the success of today's ornamentals and nursery industries. His leadership and writings created the scientific framework for research and teaching on soil-borne plant pathogens and biological control. After B.Sc. and Ph.D. degrees from Washington State University in 1930 and 1934, respectively, and one year as a National Research Council Fellow with B.M. Dugger at Wisconsin, he took jobs in 1935 with the U.S. Department of Agriculture in Nebraska on establishment of shelter belts and 1936-39 with the Pineapple Producers Cooperative Association in Hawaii. He worked on diseases of ornamental plants at the University of California, Los Angeles, starting in 1939, moving to Berkeley in 1961 when the UCLA program closed. He retired in 1975 and moved to Corvallis, OR, as Emeritus Professor, Oregon State University, and Collaborator, U.S. Department of Agriculture, Agricultural Research Service. He spent four sabbatical leaves in Australia, and was elected fellow of the American Association for the Advancement of Science in 1950, fellow of the American Phytopathological Society in 1969, and the Horticultural Hall of Fame in 1976.

Role of plant pathology in integrated pest management.

Integrated Pest Management (IPM) is a paradigm that is widely adopted by all pest control disciplines but whose early definitions and philosophical basis belong to entomologists. Plant pathology research and extension work has historically emphasized integration of several control strategies and fits both historical and modern definitions of IPM. While the term IPM has been used only sparingly in the phytopathology literature, the integrated disease management strategies emphasized are now considered to be at the forefront of ecologically based or biointensive pest management. While IPM is broadly endorsed by crop protection disciplines, farmers, other agriculturalists, and consumers, the potential for Integrated Pest Management has not been fully realized. Most IPM programs reflect a package of tools and decision aids for individual crop insect, weed, nematode, and plant disease management. IPM programs that integrate all types of pests with the agroecosystem, crop growth and loss models still await the formation of interdisciplinary teams focusing on growers needs. Lack of funding for both discipline and interdisciplinary developmental research and implementation is responsible for the paucity of comprehensive IPM programs for the majority of the U.S. crop acreage. This review explores the origins and evolution of the IPM paradigm and reviews efforts to achieve the body of knowledge and implementation structure to achieve IPM's full potential.

TALEs, TALENs, and TALE Base Editors: From Plant Pathology to Biotechnology.

TALEs (transcription activator-like effectors) are an excellent example of how studying pathogen-host interactions can lead to significant biotechnology inventions. TALEs are bacterial effectors that are translocated into plant cells via a bacterial type III secretion system. Once inside the host cell, they are imported into the nucleus to bind specific promoters and induce expression of target genes, thereby supporting the bacterial infection. TALEs are found throughout many, but not all, Xanthomonas pathovars, which can be severe pathogens of different crops. The key feature of TALEs is their modular DNA-binding domain, which allows a simple evolutionary adaptation to novel DNA sequences as well as simple cloning of designer TALEs with desired DNA-binding specificity. Accordingly, TALE nucleases started the genome-editing revolution, and TALE base editors are the latest tools to efficiently edit chloroplast and mitochondrial genomes. We review recent advances in Xanthomonas genomics, synthesize current knowledge about naturally occurring TALEs, and highlight current roles of TALEs in genome editing and synthetic biology.
