Late 1950's through the 1960's: Plant cyto- , chemo- and numerical systematics of several genera of
Asteraceae [(Zinnia, Tragoceras, Sanvitalia et al.); about 20 publications.
1970's: Isozyme genetics, especially the genetics, structure and function of sunflower alcohol dehydrogenase isozymes.
(about 10 publications)
Late 1970's through the 1980's: Isozyme genetics of various fruit tree crops, expecially avocados, citrus, date palms
(about 20 publications including a few book chapters)
Late 1980's to present: Paleontology, especially fossil marine green algae (about 14 publications).
About 100 in all, including a few unpublished laboratory manuals for
in general genetics, plant morphology and
statistics used in genetics, some in Spanish. Some of the published works include:
1967. Prácticas para biología generál. Editoriál Universidád de Oriente, Cumaná, Venezuela. ix + 75 pp.
1968. Algunas plantas leñosas de Cumaná. Editoriál Universidád de Oriente, Cumaná, Venezuela. 134 pp.
1970. With R.L. Costello, R. Smith
B. Schmidt. A laboratory manual for General Botany.
Dubuque, Iowa. vi + 217 pp.
1971. With M.W. Katz. Estadística applicada a genética generál. Regional Technical Aids Center, Mexico. 48 pp.
The papers that follow were accounts
of some aspects of the ethnobiology of Amerindians of the Orinoco
and a report on an
exchange program between the University of Kansas and the Universidád de Oriente in eastern Venezuela.
1968. Notas sobre la etnobiología de los Guaraunos. Oriente, Año l, no. 3, pp. 68-81.
1968. Plan KUUDO; An experiment
in a new dimension of university responsibility. Bulletin of the
American Association of University
Some particularly exciting research projects were reported in the following publications:
1974. Sunflower alcohol dehydrogenase: Adh-1 genetics and dissociation-recombination. Biochemical Genetics, 11:17-24. and,
1976. Dissociation-recombination of
sunflower alcohol dehydrogenase isozymes and relative isozyme
Biochemical Genetics, 14:87-98. These papers report the first time that our lab had taken two different dimeric isozymes
apart into their constituent monomers and put them back together again in new combinations. Now, of course, this process
is no doubt routine.
1978. With U. Diedenhofen, B.O.
and R.J. Knight. Enzyme polymorphisms as genetic markers in
the avocado. American
Journal of Botany, 65:134-139. This was the beginning of using fruit crop isozymes as markers to examine different problems
in different crops. My introduction to horticulture and to long and wonderful collaborations with horticultural geneticists
Bob Bergh and Bob Soost, UC-Riverside, California. I was quite pleased that a scientist from Kansas, where none of these
crops can grow, was involved with starting this field.
1980. Soost, R.K. T.E. Williams and
Torres. Identification of nucellar and zygotic seedlings of
with leaf isozymes.
Horticultural Science, 15:728-729, and,
1982. With R.K. Soost and T.
Citrus isozymes: Genetics and distinguishing nucellar from
of Heredity, 73:335-339. An innovative use of isozymes to address an age old problem in citrus breeding, identifying the
genetic origins of seedlings from polyembryonic seeds years before valuable resources were invested in culturing them.
1999. A three-dimensional CT
scan through a rock with Permian Alga Ivanovia tebagaensis. Journal
73:154-158. A detailed study of some morphological features of embedded alga from nondestructive CT scans.
2003. With A. M. Christensen, T. E. Masters
and R. A. Ketcham. From CT scan of embedded Ivanovia to models
2003. Sexual reproductive structures in the green alga Ivanovia triassica. Lethaia, 36:33-40.
Current research interests include study of
a Triassic Ivanovia from
a Yukon terrane, and attempts to use CT scans of beautifully
preserved Tunisian Ivanovia tebagaensis to make 3-D models of the cup-shaped macroscopic fossils.
Over the years research has been supported by: The Wisconsin Alumni Research Foundation; The National Science Foundation; The University of Kansas Biomed and General Research Funds; The California Avocado Advisory Board; The U.S. Department of Agriculture; The U.S.-Israel Binational Agricultural Research and Development Fund; The Australian Commonwealth Scientific and Industrial Research Organization.
I have been a consultant for: The American Institutes for Research, The Agency for International Development and The Ford Foundation on matters of Latin American higher education; TheDuPont Company on systematics problems; The Agricultural Research Organization, Bet Dagan, Israel, on avocado genetics. The Jacques Seed Company on sunflower isozymes; The Division of Horticulture, Commonwealth Scientific and Industrial Research Organization, Adelaide and Merbein, Australia on tree crop isozymes.
