Genetics of nitrogen fixation : (nitrogenase, molybdenum, ammonium excretion, legumes)
(University of Missouri, Agricultural Experiment Station, 1977)
mutant phenotype causes the plant to fix more nitrogen than the wild type. Such strains might have potential use in agriculture....
Historical aspects and significance of the discovery of wild wheats : (origin of wheat, evolution, gene pools)
(University of Missouri, Agricultural Experiment Station, 1977)
On the organization of DNA in isolated bacterial chromosomes : (bacterial DNA, folded chromosomes, EM, RNA)
(University of Missouri, Agricultural Experiment Station, 1977)
We review physical studies and electron microscopy of membrane-free folded chromosomes from E. coli [Kavenoff and Bowen, Chromosoma 59, 89 (1977)], and we consider the apparent relation between the organization of the DNA ...
A gene-enzyme relationship in neurospora : (neurospora, complementation, amino acid substitutions, chain termination, suppression, osmotic repair)
(University of Missouri, Agricultural Experiment Station, 1977)
The results of work on amino acid replacements in NADP-specific glutamatede hydrogenase of Neurospora crassa, due to mutation in the am gene, are reviewed: amino acid residues which are important in coenzyme binding and ...
Extension of BrdU-dye analysis of DNA replication and sister chromatid exchange formation to in vivo systems : (in vivo, BrdU-dye, DNA replication, sister chromatid exchange)
(University of Missouri, Agricultural Experiment Station, 1977)
BrdU-dye methodology was initially developed in tissue culture. Wide application of the technique for cytogenetic studies of DNA structure, replication and repair followed. Although the need for parallel in vivo studies ...
The genetic complexity of the R locus in maize : (gene complex, regulatory elements, paramutation)
(University of Missouri, Agricultural Experiment Station, 1977)
The evidence on the compound structure of the R locus is reviewed. The more recent analysis of another group of R accessions, collectively known as R-cherry, seems to indicate that this locus is a gene cluster separable ...
A genetic pathway for dauer larva formation in caenorhabditis elegans : (nematode, development, neuron)
(University of Missouri, Agricultural Experiment Station, 1977)
C. elegans is a roundworm, a free-living soil nematode. The dauer larva is a non-feeding, non-growing larval stage which is formed under conditions of starvation. It possesses a relatively impermeable cuticle and differs ...
Polypeptide composition of fraction I protein as an aid in the study of plant evolution : (chloroplast DNA, age of genera and species, origin of genomes, composition of proteins as affected by amphiploidy)
(University of Missouri, Agricultural Experiment Station, 1977)
Fraction 1 protein (F-1-P), found in all green plants, consists of eight large subunits (LS) coded by chloroplast DNA and eight small subunits (SS) coded by nuclear DNA. By electrofocusing in 8M urea many different species ...
Analysis of gene number and development in polygenic systems : (polygenes, variation, selection, pattern)
(University of Missouri, Agricultural Experiment Station, 1977)
The assumption that quantitative variation is produced by a large number of genes is re-examined. In fact, one finds that often only a small number of loci are involved. This, therefore, opens to careful study the developmental ...
Chromatin as a model system for studying the regulation of histone gene expression in mammalian cells : (mRNA, chromosomal proteins, transcription, cell cycle)
(University of Missouri, Agricultural Experiment Station, 1977)
Histone gene expression was studied during the cell cycle of continuously dividing HeLa S3 cells and after stimulation of confluent monolayers of WI-38 human diploid fibroblasts to proliferate. The presence of histone mRNA ...
