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 intergenic sunflower alcohol dehydrogenase isozymes and relative isozyme activities.
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. Bergh, 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 A.M. Torres. Identification of nucellar and zygotic seedlings of Citrus with leaf isozymes.
Horticultural Science, 15:728-729, and,
1982. With R.K. Soost and T. Mau-Lastovicka. Citrus isozymes: Genetics and distinguishing nucellar from zygotic seedings. Journal
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 (CAT) scan through a rock with Permian Alga Ivanovia tebagaensis. Journal of Paleontology,
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 using rapid prototyping.
