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 ...
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 ...
Transposable elements and genetic instabilities in crop plants : (controlling elements, recurrent mutations, hybrid dysgenesis, somatic mutations, tissue culture)
(University of Missouri, Agricultural Experiment Station, 1981)
Transposable elements have long been associated with certain unstable loci in maize and have been intensively studied by McClintock and others. It is known that a transposable element can control the expression of the ...
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 ...
