Robert E. Stall - CV
Professor (90% Research and 10% Teaching)
Education:
Ohio State University, B. Sc. 1953, M. Sc., 1954, PhD 1957.
Professional Experience:
- 195357 Research Assistant, Ohio Agr. Exp. Sta., Wooster, Ohio
- 195764 Ass't and Assoc. Plant Pathologist, Indian River Field Laboratory, Florida Agr. Exp. Sta. Ft. Pierce
- 1964present Assoc. Professor and Professor, Dept. of Plant Pathology, IFAS. University of Florida, Gainesville
- 197879 Citrus canker project, INTA, Bella Vista, Argentina
- 1984 Visiting Professor, Dept. Plant Pathology, University of California, Berkeley.
Responsibilities:
Primary responsibilities include investigations ofthe etiology of diseases; and the ecological behavior of plant pathogenic bacteria. The physiological factors involved in pathogenicity of bacteria to plants and the genetic complement of the bacteria necessary for pathogenicity is investigated. The inheritance of resistance in plants to bacterial plant pathogens and the mechanisms of resistance in plants is researched. Chemicals are evaluated as sprays for control of bacterial diseases and resistance of the pathogen to the chemicals is studied.
A graduate level course on Bacterial Phytopathology is taught every other year. Graduate students wishing to obtained advanced degrees working with a bacterial plant pathogen are advised.
International Programs:
Cooperation with faculty at INTA Stations at Concordia and Bella Vista, Argentina working on citrus canker. Cooperation with Plant Pathologist at Asian Vegetable Research and Development Center, Shanhua, Taiwan on detection of bacterial pathogens on seeds.
Accomplishments:
- With B. Staskawicz, U. Bonas, M. Whalen, and G. Minsavage cloned and characterized avirulence genes and hrpgenes in Xcampestris pv.vesicatoria.
- With J. Jones developed polyphasic analysis of populations of Xcampestris pv.vesicatoria from around the world and discovered that two distinct xanthomonads were in the populations, both of which cause bacterial spot of tomato and pepper.
- With B. Canteros, J. Jones, and G. Minsavage demonstrated wide diversity of plasmids in Xcampestris pv.vesicatoria and the transfer of some of them in nature.
- With J-F. Wang, J. Scott, J. Jones, and E. Vallejos characterized resistance genes in tomato for bacterial spot resistance. One hypersensitive resistance is controlled by at least three genes. All three genes were mapped in tomato genome by isozyme and RFLP markers.
- With G. Minsavage developed a PCR method to detect the watermelon fruit blotch pathogen on watermelon seeds.
Honors and Awards:
Fellow Arnerican Phytopathological Society. Distinguished Alurnnus Award Ohio State University. Plant Protection Award of Eminence Florida Dept. of Agr. and Cons. Services. Annual Research Award Florida Fruit and Vegetable Association. Certificate of Appreciation United States Departrnent of Agriculture.
Grants and Contracts:
Currently grants from USDACBAG and Arnerican Seed Trade Association support work. Also numerous small gifts have been received from Seed Companies.
Graduate Students:
Major advisor for 15 students that received M. Sc. degree and for 11 students that received PhD degree. Four Postdoctoral Associates have worked in our lab.
