A genetic pathway for dauer larva formation in caenorhabditis elegans : (nematode, development, neuron)
(University of Missouri, Agricultural Experiment Station, 1977)
C. elegans is a roundworm, a free-living soil nematode. The dauer larva is a non-feeding, non-growing larval stage which is formed under conditions of starvation. It possesses a relatively impermeable cuticle and differs ...
Polypeptide composition of fraction I protein as an aid in the study of plant evolution : (chloroplast DNA, age of genera and species, origin of genomes, composition of proteins as affected by amphiploidy)
(University of Missouri, Agricultural Experiment Station, 1977)
Fraction 1 protein (F-1-P), found in all green plants, consists of eight large subunits (LS) coded by chloroplast DNA and eight small subunits (SS) coded by nuclear DNA. By electrofocusing in 8M urea many different species ...
Mechanisms that rapidly reorganize the genome : (genome reorganizations, transposable gene control systems, restriction enzymes, stabilizing mechanisms)
(University of Missouri, Agricultural Experiment Station, 1978)
Extensive reorganization of components of the genome is initiated in maize by the breakage-fusion-bridge (BFB) cycle. Displacements include chromosomes other than those undergoing the cycle. Restructuring ranges from those ...
Mutagenic mechanisms in bacteriophage T4 : (bacteriophage T4, mutagenic mechanisms, heat mutagenesis)
(University of Missouri, Agricultural Experiment Station, 1976)
Mutagenic mechanisms can be divided into two categories, those dependent upon specific base mispairing (generating base pair substitutions and frameshift mutations) and those dependent upon misrepair (perhaps as a result ...
Genetic Regulation of fermentation organisms : fermentation, regulation, antibiotics
(University of Missouri, Agricultural Experiment Station, 1976)
An effective fermentation organism is a wasteful creature that overproduces and excretes its metabolic intermediates and end products. Cultures obtained from screening programs usually possess subnormal regulatory controls. ...
Gene conversion in unselected tetrads from multipoint crosses
(University of Missouri, Agricultural Experiment Station, 1971)
Some cytogenetic aaspects of the mechanism of recombination of the genome in diploid plant species
(University of Missouri, Agricultural Experiment Station, 1971)
Genetic approaches to the study of ribosomes
(University of Missouri, Agricultural Experiment Station, 1976)
Specific mutants of Escherichia coli have been used in order to investigate certain aspects of ribosome function, bio synthesis and decay. These studies show that in the function of the ribosome its various components are ...
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 ...
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 ...
Aphrodisiacs and anaphrodisiacs : better loving through chemistry : reproduction, behavior, pheromones, love potions, biological control
(University of Missouri, Agricultural Experiment Station, 1976)
Reproductive behavior in animals is modulated by an assortment of chemical signals. This paper focuses on substances that are externally emitted and are effective when a male and female are near or in contact with each ...
Characteristics of cms-S reveversion to male fertility in maize : (cytoplasmic male sterility, male fertility restoration S-type cytoplasm, mitochondrial DNA)
(University of Missouri, Agricultural Experiment Station, 1981)
The association of cytoplasmic reversion of cms-S male-sterile strains to male fertility with disappearance of the S1 and S2 mtDNA plasmids as discrete molecules has been established for all 23 cytoplasmic revertant strains ...
Divergent and concerted evolution of the two regions encompassing the iso-1- cytochrome c and iso-2-cytochrome c genes of yeast : (saccharomyces cerevisiae, cytochrome c of yeast, evolution of yeast, cloning yeast genes, recombinant DNA, transpositions, composite genes)
(University of Missouri, Agricultural Experiment Station, 1982)
The yeast Saccharomyces cerevisiae contains a cluster of three genes CYC1-0SM1-RAD7, denoted COR, located on the right arm of chromosome X and a cluster of three genes ANP1-RAD23 -C YC7, denoted ARC, located on the left ...
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 ...
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 ...
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 ...
Quantitative analysis of Iowa stiff stalk synthetic
(University of Missouri, Agricultural Experiment Station, 1983)
Stiff Stalk Synthetic is a synthetic variety that was deloped in the early 1930's by recombining 16 inbred lines that were considered to be above average for stalk quality. Because of the origin of the lines included in ...
Chromatin as a model system for studying the regulation of histone gene expression in mammalian cells : (mRNA, chromosomal proteins, transcription, cell cycle)
(University of Missouri, Agricultural Experiment Station, 1977)
Histone gene expression was studied during the cell cycle of continuously dividing HeLa S3 cells and after stimulation of confluent monolayers of WI-38 human diploid fibroblasts to proliferate. The presence of histone mRNA ...
