Meiotic aspects of chromosome organization : (meiosis, pachytene DNA)
(University of Missouri, Agricultural Experiment Station, 1983)
Homologous chromosome pairing regulates the expression of a set of metabolic activities that is unique to the zygotene-pachytene interval , These activities probably relate to crossing-over and they involve specific proteins ...
A molecular analysis of three unstable alleles in drosophila : (transposable elements, mutable alleles, white locus)
(University of Missouri, Agricultural Experiment Station, 1982)
We have determined the structure of several unstable mutant alleles of the white locus in Drosophila melanogaster. The white ivory (w[superscript i]) allele is a moderately unstable allele, which gave rise to the highly ...
Heterogeneity and expression of the zein storage protein gene family of maize : (zein, maize, multiple gene families, in vitro processing, protein synthesis, cloning, low molecular weight PAGE)
(University of Missouri, Agricultural Experiment Station, 1981)
The storage protein zein is synthesized by polysomes on the endoplasmic reticulum in certain cells of the maize seed. As zein accumulates within the membrane lumen the cisternae are transformed into vesiculate protein ...
The structure and function of yeast centromeres : (saccharomyces cerevisiae, yeast transformation, centromere cloning, functional minichromosomes , recombinant DNA, nucleotide sequencing )
(University of Missouri, Agricultural Experiment Station, 1981)
Segments of Saccharomyces cerevisiae DNA have been isolated that contain centromeric sequences (CEN3 and CEN11) from chromosomes III and XI. When present on a plasmid vector capable of replication in yeast (pLC544 or Yrp7), ...
The mechanism and control of Tn5 transposition
(University of Missouri, Agricultural Experiment Station, 1982)
Analyses of transposition from pBR322
Chromatin structure of eukaryotic genes : DNase I hypersensitive sites
(University of Missouri, Agricultural Experiment Station, 1982)
We have recently learned much about the organization of the eukaryotic genome by using nucleases as probes of the protein - DNA interactions of chromatin. In this paper we review the available information from our laboratory ...
Chi sites, RecBC enzyme, and geneneralized recombination
(University of Missouri, Agricultural Experiment Station, 1981)
With the goal of elucidating the molecular basis of genetic recombination, our laboratory has studied special sites that promote recombination in their neighborhood and enzymes essential for recombination in Escherichia ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
