On the organization of DNA in isolated bacterial chromosomes : (bacterial DNA, folded chromosomes, EM, RNA)
(University of Missouri, Agricultural Experiment Station, 1977)
We review physical studies and electron microscopy of membrane-free folded chromosomes from E. coli [Kavenoff and Bowen, Chromosoma 59, 89 (1977)], and we consider the apparent relation between the organization of the DNA ...
Repertoire of genetic control of gene expression in procaryotes
(University of Missouri, Agricultural Experiment Station, 1971)
Writing 18 years ago, DR. STADLER pointed out that because of limitations in the knowledge and definition of the gene, questions about undetermined properties of the gene--the nature of the unit of reproduction, the unit ...
Speciation and the founder principle
(University of Missouri, Agricultural Experiment Station, 1971)
The role of tRNA in development
(University of Missouri, Agricultural Experiment Station, 1972)
Experiments that suggest a developmental regulatory role for tRNA in translation (such cytokinins in tRNA, suppressor mutations, tRNA methyases, excessive number of isoaccepting species, and others) are briefly presented. Reports that link changes...
Some cytogenetic aaspects of the mechanism of recombination of the genome in diploid plant species
(University of Missouri, Agricultural Experiment Station, 1971)
Flower differentiation in arabidopsis
(University of Missouri, Agricultural Experiment Station, 1974)
There is a consensus among developmental geneticists that few generalizations are possible at the present status of the field, and even the boundaries are difficult to define. Yet in few special cases, consistent facts have been accumulated which...
Neurospora as an object for cytogenetic research : chromosome rearrangements, crossing over, duplications, meiosis, meiotic drive, recombination
(University of Missouri, Agricultural Experiment Station, 1979)
Several lines of research have been stimulated because the direct results of Mendelian segregation are apparent in Neurospora asci. Spore killer genes provide an example. When across is heterozygous for Spore killer, four ...
Analysis of gene number and development in polygenic systems : (polygenes, variation, selection, pattern)
(University of Missouri, Agricultural Experiment Station, 1977)
The assumption that quantitative variation is produced by a large number of genes is re-examined. In fact, one finds that often only a small number of loci are involved. This, therefore, opens to careful study the developmental ...
Pattern formation in the drosophila embryo : (Developmental genetics, combinatorial code, compartments)
(University of Missouri, Agricultural Experiment Station, 1981)
Three plausible hypotheses about developmental commitments in the Drosophila embryo propose: 1) A micromosaic of localized determinants in the egg trigger somatic commitments. 2) Monotonic anterior-posterior and dorsal-ventral ...
