Where will the next Norman Borlaug come from? A U.S. perspective of plant pathology education and research.

Abstract

Plant diseases can be traced back almost as far as recorded history. Numerous ancient writings describe plagues and blasts destroying crops and modern civilization still faces many plant disease challenges. Plant pathology has its roots in botany and notable scientists such as Tillet, Prevost, and deBary already had concluded microscopic organisms could cause plant diseases before Robert Koch established the rules of proof of pathogenicity with sheep anthrax. Plant pathologists can be credited with helping improve crop yields and food production throughout the world. However, at a time when there are increasing challenges to crop production, some that potentially may increase the severity or distribution of plant diseases, the training of future plant pathologists appears to be declining, at least in the United States. The ability of the U.S. Land Grant University (USLGU) system to attract and train future generations of plant pathologists may be at risk. Recent data from university plant pathology departments collected by The American Phytopathological Society (APS) documents a decline in the number of students completing advanced degrees in plant pathology, departments with fewer faculty with a diverse expertise in applied plant pathology, fewer stand-alone, single discipline departments of plant pathology, a reduced ability of many departments to offer specific curricular aspects of plant pathology, and a demographic profile that casts an ominous prediction for an unusually large number of faculty retirements over the next decade. The impact of these factors could be a shortage of highly skilled, applied plant pathologists in the U.S. in coming years. The affect also may be felt globally as fewer international students may receive predoctoral and post-doctoral training in plant pathology in the U.S. as faculty retire and are not replaced. On the other hand, this likely will create greater opportunities for universities around the world to take leadership in many aspects of plant pathology education. While a decline in students and young faculty trained in applied and field-level specialties of plant pathology (mycology, bacteriology, plant nematology, forest pathology, epidemiology, etc.) is occurring, those trained in the cellular and molecular host-pathogen interactions specialties appear to be increasing. Many plant pathology faculty hired at USLGUs in the last decade are trained in molecular biology and received their Ph.D. degree in a field other than plant pathology. They are now applying those skills to research numerous aspects of host-pathogen interactions of model pathosystems. A shift to a greater research emphasis on molecular host-pathogen interactions over the last decade is evidenced by the number of research articles published in the three APS journals; Plant Disease, Phytopathology and Molecular PlantMicrobe Interactions (MPMI). From 1985 to 2007, there has been a decline in the number of articles published in Plant Disease (-29%) and Phytopathology (-36%) and a steady increase in those publi...

The Future of Forest Pathology in North America

“…The field of forest pathology is not new: it has developed over 130 years, stimulated by the severe impact of nonnative, pathogen-caused epidemics during the first half of the twentieth century and with the purpose of preventing or controlling such events in the future (Boyce, 1961). Since the early 1980s, forest pathology positions in academia and the federal government in North America have undergone a steep decline, despite the significant increase in emerging pest issues (Martyn, 2009;Santini et al, 2013;Bonello et al, 2020b). Lack of trained personnel has occurred in tandem with reductions in organizationally visible forest pathology programs across forestry and plant pathology departments throughout the U.S. and Canada.…”

“…However, future generations of forest pathologists will require even more multidisciplinary training and approaches. They will need to acquire multidisciplinary knowledge to better characterize diverse pathosystems (Martyn, 2009). Furthermore, it is critical that resource opportunities sufficient to support the clear needs identified here be strategic, focused, and applied across the continuum of basic to applied research and solution implementation.…”
