Genetics and evolution of the chloroplast : (cytoplasmic inheritance, nucleus-cytoplasm interaction, plastome recombination, plastome mutator, oenothera)
(University of Missouri, Agricultural Experiment Station, 1983)
As a photosynthetic organelle and as the site of several important biosynthetic pathways, the chloroplast is essential to the survival of the plant cell. In evolutionary terms, the chloroplast genetic material can be ...
Measures of fitness in Drosophila : (population genetics, Drosophila, fitness, natural selection)
(University of Missouri, Agricultural Experiment Station, 1983)
Ten proposed experimental measures of fitness in Drosophila have been estimated in 8 to 38 strains of D. melanogaster with 1 to 6 replications in order to assess the degree of association among the measures. One measure ...
Chromosome manipulation and its exploitation in the genetics and breeding of wheat
(University of Missouri, Agricultural Experiment Station, 1983)
Chromosome manipulation in bread wheat uses aneuploid methods to transfer whole chromosomes or segments of chromosomes from one variety into another, or from related species into wheat. These methods have been applied ...
Molecular and developmental cytogenetics of gene multiplicity in maize : maize, cytogenetics, ribosomal RNA, endosperm, gametes
(University of Missouri, Agricultural Experiment Station, 1983)
Gene multiplicity alterations may be an important feature of maize developmental biology. A developmentally-phased change in DNA level has been found to be a striking feature of maize endosperm growth. I n the central ...
Some notes on premeiocytes in wheat : (premeiotic mitosis, premeiotic interphase, archesporial cell, pollen mother cell)
(University of Missouri, Agricultural Experiment Station, 1983)
Some characteristics of wheat premeiocytes are described as they appear in electron microscopy. These include changes in the endoplasmic reticulum of archesporial cells in premeiotic mitosis (PMM) and some nuclear and ...
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 ...
Monocot and dicot genes encoding the small subunit ofribulose-1,5-bisphosphate carboxylase : structural analysis and gene expression
(University of Missouri, Agricultural Experiment Station, 1983)
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 ...
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 ...
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 ...
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 ...
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), ...
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 ...
