An anatomical study of the needles and hypocotyls of Douglas-fir seedlings grown under various environments

Creator:: Tucker, Richard Edward
Abstract:: Two seed sources of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seedlings were grown under several environments in controlled growth chambers and in a natural environment. All seedlings were grown for six months and then harvested. One purpose of this study was to observe environmental influences on the anatomy of the needle....

Evidence for a soluble intermediate of oxidative phosphorylation isolated from cabbage mitochondria

Creator:: Johnson, Morris Alfred
Abstract:: An intermediate of oxidative phosphorylation was apparently solubilized from cabbage mitochondria. The method of solubilization used primarily was extraction of a mitochondrial acetone powder with 0.1 M glycylglycine, pH 7.4, at 4° C. The intermediate betrayed its presence by causing the transfer of Pi³² to ADP with the resultant formation...

Methodology for cuticular identification of selected eastern Oregon range plants

Creator:: Schrumpf, Barry J.
Abstract:: Animal dietary preferences have been studied by feeding-site examinations, animal observation, and stomach and esophageal collections. Analysis of fecal material for undigested plant cuticle is another means for obtaining the same information. This study was conducted to: (1) prepare a microscope slide series depicting the surface features of leaves and...

The effects of univalent cations on the inductive formation of nitrate reductase

Creator:: Nitsos, Ronald Eugene
Abstract:: An investigation was undertaken to determine whether potassium is indeed necessary for the in vivo synthesis of a specific protein. The effects of univalent cations on the inductive formation of nitrate reductase and on the level of activity of representative non-adaptive enzyme are presented. Cultures of Neurospora crassa were grown...

Qualitative changes in cytoplasmic proteins in plants treated with plant growth regulating chemicals

Creator:: Norris, L. A.
Abstract:: This thesis concerns the alteration of the course of selective protein synthesis and morphogenesis in plants treated with growth regulating chemicals. Treatment of 48-hour-old "Alaska" pea seedlings (Pisum sativum L.) with 2, 4-D, IAA, NAA or picloram caused inhibition of epicotyl and primary root elongation and proliferation of massed lateral...

Nature of calcium uptake by plants

Creator:: Silva Norambuena, Bernardo
Abstract:: Cucumber, pea, bean, and corn excised roots were used to assess species differences in metabolic uptake of calcium It was found that Ca was mostly taken up by these root systems by non-metabolic processes. The apparent free space ranged from 26 to 28 percent of the total root volume and...

Some properties of ribonucleotide reductase in Rhizobium species

Creator:: Cowles, Joe Richard, 1941-
Abstract:: Ribonucleotide reductase from Rhizobium meliloti has been partially purified and characterized. The enzymatic reduction of ribonucleotides to deoxyribonucleotides is dependent upon B₁₂ coenzyme and dihydrolipoate. B₁₂ coenzyme was more effective than B₁₂ coenzyme analogues in the reductase reaction. The affinity of the R. meliloti reductase system for B₁₂ coenzyme was...
