The mitochondrial genome of higher plants : mtiochondrial DNA, cytoplasmic male sterility, S cytoplasm
(University of Missouri, Agricultural Experiment Station, 1978)
Mitochondrial (mt) DNAs of higher plants have molecular weights ranging from 70-165 x 10 [superscript 6], which is by far the largest found in nature. Their native configuration is probably a covalently closed circular ...
Organization of a gene in drosophila : a progress report : Drosophila melanogaster, rosy Zocus, XDH, genetic fine structure, peptide coding region, cis-acting control element
(University of Missouri, Agricultural Experiment Station, 1978)
The present report summarizes our progress in the genetic dissection of an elementary genetic unit in a higher organism. The rosy locus (ry:3-52.0) in Drosophila melanogaster codes for xanthine dehydrogenase, and is ...
Non-Darwinian evolution and the bread of life : genetic drift, repetitive DNA, philosophy of science
(University of Missouri, Agricultural Experiment Station, 1978)
This paper explores what would happen to a chromosomal segment that evolves randomly, without the surveillance of natural selection. In these circumstances a single segment present in some individual organism at any given ...
The organization of the QA gene cluster in neurospora crassa and its expression in escherichia coli : eucaryotic gene regulation, quinic acid catabolic enzymes, recombinant DNA, pBR322 plasmid
(University of Missouri, Agricultural Experiment Station, 1978)

Bacteriophage T4 and our present concept of the gene
(University of Missouri, Agricultural Experiment Station, 1971)
Evolution of DNA sequence : mechanisms and models as seen in small phages : (small isometric phages, evolution of their nucleotide sequence, duplication, deletion, overlapping genes, secondary structure)
(University of Missouri, Agricultural Experiment Station, 1980)
Extensive nucleotide sequence data is new known for six small isometric phages, ([o with diagonal slash]Xl 74, G4, St-1, Sl3, [lowercase alpha]3 and [phi]K).Comparison of these sequences allows us to observe the role of ...
Viroids : minimal genetic systems : (RNA, plant pathogens, replication, pathogenesis)
(University of Missouri, Agricultural Experiment Station, 1980)
SViroids are nucleic acid species of relatively low molecular weight and unique structure that cause several important diseases of cultivated plants. Viroids are the smallest known agents of infectious disease. Unlike viral ...
Neurogenetics of courtship in drosophila : (courtship and mating, behavioral mutants, Drosophila gynandromorphs, visual and olfactory defects, circadian rhythms, learning and memory, neurotransmitter mutants)
(University of Missouri, Agricultural Experiment Station, 1980)
Courtship behavior in Drosophila is programmed by the action of genes that control the development and function of the nervous system. Several genes have been identified that appear to be involved in reproduction, because ...
The integration of human DNA and expression tumor virus genes : (cell transformation, transcription, integration, human cancer)
(University of Missouri, Agricultural Experiment Station, 1980)
DNA tumor viruses offer excellent model systems to study the molecular biology of eucaryotic cells and to establish the molecular basis for cell transformation. Our laboratory has focused on the human adenovirus type 2 ...
Evolution of the bacterial genome : (bacterial DNA evolution, vertical vs. horizontal evolution)
(University of Missouri, Agricultural Experiment Station, 1980)
Not all parts of bacterial genomes have evolved at the same rate. Among related genomes, some gene segments are highly conserved, some are less conserved and some are highly variable. We have studied the relatedness of ...
Nitrogen fixation by photosynthetic bacteria : (Rhodospirilum rubrum, Rhodopseudomonas capsulata, glutamine ,nitrogenase)
(University of Missouri, Agricultural Experiment Station, 1980)
Biological nitrogen fixation is not only essential for world nitrogen balance but it is also an alternative to expensive commercial fertilizer for crop production. To achieve the maximum utilization of this natural process, ...
Molecular evolution in papova viruses and their host species, and in bacteriophages : (evolution, nucleotide substitution, papova viruses)
(University of Missouri, Agricultural Experiment Station, 1980)
Comparing homologous genes of three papova viral genomes, we attempt to show the very close relative phylogeny among the viral species and their host species, and therefore the viral species seem to have evolved with their ...
Molecular structure of the ovalbumin gene and its genotypic alleles : (DNA cloning, intervening sequences, restriction mapping, electromicroscopic mapping)
(University of Missouri, Agricultural Experiment Station, 1979)
Medical genetics : impact and strategy : (genetic disease, birth defects, prenatal diagnosis)
(University of Missouri, Agricultural Experiment Station, 1980)
Genetic diseases and birth defects have a major impact on all levels of health care because of their enormous consequences for the individual and family and because of the high frequency of occurrence. That over 3000 ...
The topology of homologous pairing : (genetic recombination, RecA protein, strand crossover, joint molecules, heteroduplex joints, branch migration)
(University of Missouri, Agricultural Experiment Station, 1980)
The RecA protein, which is essential for genetic recombination of E. coli , promotes homologous pairing in vitro. Studies of purified RecA protein have shown that it promotes the homologous pairing of a number of topological ...
Fossils, apes, man, and culture : intelligence, water, menopause
(University of Missouri, Agricultural Experiment Station, 1979)
As causal agents for the separation of the pongid and hominid lines of evolution intelligence, water and the menopause are discussed. The implications of these for the development of human culture and society are investigated.
General genetic recombination in bacteriophage T4 : DNA exchange, DNA- protein-protein interactions
(University of Missouri, Agricultural Experiment Station, 1979)
We will discuss current models of genetic recombination emphasizing their general aspects and the specific points which have been demonstrated in phage T4. Recombination in this phage occurs preferentially (although not ...
Genetics and molecular biology of plastids of higher plants : plastids in male gametes, mutation induction, nitroso - urea, plastid mutants, thylakoid proteins, plastid ribosome deficiency, pollen, chloroplast, photosynthesis, mitochondria
(University of Missouri, Agricultural Experiment Station, 1979)
In the majority of angiospermous species the plastids are excluded from the generative or sperm cells during the first pollen mitosis or during pollen development; this is the basis of the maternal inheritance of plastid ...
