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 ...
Tailoring the agrobacterium Ti plasmid as a vector for plant genetic engineering : (site specific insertions, chimeric gene construction, regeneration of plants containing T- DNA)
(University of Missouri, Agricultural Experiment Station, 1981)
Agrobacterium tumefaciens and its tumor-inducing (Ti) plasmidi constitute a promising vector system for the introduction of desirable genes into higher plant cells. This bacterialpathogen has an unusually wide host range, ...
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), ...
Arrangement and rearrangement of the bacterial chromosome : (chromosome rearrangements, transposable elements)
(University of Missouri, Agricultural Experiment Station, 1981)
Several lines of evidence suggest that the arrangement of genes in the bacterial chromosome may have selective importance. To investigate the significance of chromosomal gene order and the effect of position on gene ...
Somatic cell genetic analysis of the interferon system : (interferon genetics, interferon receptors , cell hybrids )
(University of Missouri, Agricultural Experiment Station, 1981)
The interferon system is amenable to somatic cell genetic analysis since the genes governing the synthesis of interferon and the cellular responses to interferon can be expressed in tissue culture cells. Limited species ...
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 ...
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 ...
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 ...
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 ...
