Genetics and art
(University of Missouri, Agricultural Experiment Station, 1974)
In the view of the geneticist art is more than l'art pour l'art . In the absence of written genetic records, stone carvings, statues, reliefs and paintings reveal a great deal about the genes carried by our ancient ...
Metaphase chromosome uptake by mammalian cells and cxpression of the genes transferred
(University of Missouri, Agricultural Experiment Station, 1974)
Isolated metaphase chromosomes can be incorporated into mammalian cells. The genetic information thereby transferred, in the form of a chromosome, can be replicated and expressed in the recipient cell and its progeny, thus ...
Electronmicroscopic studies of active genes
(University of Missouri, Agricultural Experiment Station, 1974)
Structural aspects of ribosomal and non-ribosomal RNA transcription are compared and contrasted in a representative prokaryote (Escherichia coli) and in several diverse eukaryotes (developing amphibian oocytes, Drosophila ...
Developmental genetics and crop yield
(University of Missouri, Agricultural Experiment Station, 1974)
On the basis of consideration of the patterns of seed differentiation in plants and recent results of developmental genetics in Drosophila, a program is outlined for the production of crops with improved seed characteristics. ...
Metabolic organization in neurospora
(University of Missouri, Agricultural Experiment Station, 1974)
Several mechanisms of metabolite channeling have been discovered in arginine and pyrimidine biosynthesis in Neurospora. In the case of carbamyl phosphate, a pyrimidine specific "pool" of this compound is actually bound to ...
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 ...
Enzyme polymorphism and adaptation
(University of Missouri, Agricultural Experiment Station, 1975)
After a brief resume of the controversy concerning the adaptive value of enzyme polymorphisms, a physiological hypo thesis is advanced that heterosis for enzymes of intermediary metabolism results from the differential ...
Eukaryotic genes in prokaryotic cells
(University of Missouri, Agricultural Experiment Station, 1975)
"High yields of specific genes or their products can be obtained by cloning the genes (from any organism) as part of arokaryotic plasmid or virus. Furthermore the methods of microbial genetics are available for use in ...
Genome organization in higher plants
(University of Missouri, Agricultural Experiment Station, 1975)
Higher plant chromosomes contain many families of thousands of similar nucleotide sequences as well as sequences pre sent in only one or a few copies per haploid genome. We summarise here biochemical investigations into ...
Molecular coding of information in the nervous system
(University of Missouri, Agricultural Experiment Station, 1974)
Evidence has been accumulating in the last ten years to support the existence of a molecular code for the processing of information by the nervous system. The most direct evidence has been provided by the behavioral bioassay ...
The genetics of somatic mammalian cells
(University of Missouri, Agricultural Experiment Station, 1974)
Somatic cell genetics is an application of the concepts and techniques of microbial genetics to somatic cells of higher organisms. Applied to mammalian systems, it has made possible clone isolation, quantitation of cell ...
Advances in somatic cell hybridization in higher plants
(University of Missouri, Agricultural Experiment Station, 1975)
Advances in tissue culture and protoplast technology make it possible to investigate genetic manipulation of somatic plant cells. The development of a new and efficient technique has resulted in fusion of protoplasts and ...
Natural selection and adaptive resemblances
(University of Missouri, Agricultural Experiment Station, 1975)
The great majority of animal species exhibit some type of adaptive resemblance. Whether this takes the direction of cryptic resemblance of some type of mimicry is unpredictable. The evidence indicates that all adaptive ...
A few remarks on the impact of biochemistry on genectics
(University of Missouri, Agricultural Experiment Station, 1975)
Neurospora as an object for cytogenetic research : chromosome rearrangements, crossing over, duplications, meiosis, meiotic drive, recombination
(University of Missouri, Agricultural Experiment Station, 1979)
Several lines of research have been stimulated because the direct results of Mendelian segregation are apparent in Neurospora asci. Spore killer genes provide an example. When across is heterozygous for Spore killer, four ...
Role of gene duplication in the evolution of complex physiological mechanisms : an assessment based on protein sequence data : (gene duplication, protein sequences, evolutionary trees, serine proteases, immunoglobulins, evolution of muscle types)
(University of Missouri, Agricultural Experiment Station, 1979)
Genetic duplication has played a major role in the evolution of physiological complexity by creating originally redundant genes that evolved to produce related proteins in the organism. The related chains of certain polymeric ...
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 ...
Genetics and molecular biology of plastids of higher plants : plastids in male gametes, mutation induction, nitroso - urea, plastid mutants, thylakoid proteins, plastid ribosome deficiency, pollen, chloroplast, photosynthesis, mitochondria
(University of Missouri, Agricultural Experiment Station, 1979)
In the majority of angiospermous species the plastids are excluded from the generative or sperm cells during the first pollen mitosis or during pollen development; this is the basis of the maternal inheritance of plastid ...
Ti plasmids of agrobacterium : potentials for genetic engineering : plasmids, genetic engineering, crown gall, tumors
(University of Missouri, Agricultural Experiment Station, 1979)
Crown gall disease of dicotylendenous plants, induced by Agrobacterium tumefaciens, provides a unique system for the study of pathogen-host interplay at the molecular level. By means of large Ti plasmids borne by virulent ...
Genetical and chromosomal relationships among the wheats and their relatives : aneuploid genetics, isozymes, gene and chromosome evolution, triticum, wheat
(University of Missouri, Agricultural Experiment Station, 1979)
Results obtained from aneuploid genetic analyses of isozyme variation in hexaploid wheat have led to the construction of reasonable models for the genetic control and subunit structure of a large number of enzymes. Evidence ...
