Functional Analysis Of Maize Gbssi And Ssi : Characterization Of Recombinant Chimeric Proteins, Rachel Carol Huegel Jan 2005

Functional Analysis Of Maize Gbssi And Ssi : Characterization Of Recombinant Chimeric Proteins, Rachel Carol Huegel

Retrospective Theses and Dissertations

Starch is a semi-crystalline glucose polymer synthesized in higher plants for the efficient storage of a large amount of glucose in plastids without osmotic consequences. Amylose and amylopectin are two different glucose polymers that make up the starch granule which are created from adenosine 5' diphosphate glucose (ADPG) via starch synthases (SS's), branching enzymes (BE's), debranching enzymes (DBE's), starch phosphorylase (SP), and disproportionating enzyme (D-enzyme). This focus of this research is to learn more about SS's exact structure and function. There are five known SS's in maize including granule bound starch synthase I (GBSSI), starch ...


Propagation Of Alnus Maritima From Its Three Disjunct Populations, James Alan Schrader Jan 1999

Propagation Of Alnus Maritima From Its Three Disjunct Populations, James Alan Schrader

Retrospective Theses and Dissertations

My third objective was to evaluate the use of softwood cuttings to propagate A. maritima. Indole-3-butyric acid (IBA) at 8 g·kg⁻¹ caused a greater rooting percentage (68%), root count (36), and root length (9.1 cm) than did IBA at 0 and 1 g·kg⁻¹ when applied to cuttings from Oklahoma in June. Cuttings from Oklahoma had greater survival, callus development, and root length, and had a higher rooting percentage and root count, than cuttings from Delmarva. More cuttings collected 14 June rooted (41%) than those collected 23 Aug. (8%). This information will ...


Effects Of Stress Temperatures Of Germination On Polyamine Titers Of Soybean Seeds , Renan Pineda Mejia Jan 1999

Effects Of Stress Temperatures Of Germination On Polyamine Titers Of Soybean Seeds , Renan Pineda Mejia

Retrospective Theses and Dissertations

High and low stress temperatures during seed germination and seedling development limit total germination and the rate of germination and growth. Changes in polyamine (PA) concentrations in seeds of different species have been associated with germination, growth and environmental stresses such as temperature, drought, oxygen, chilling injury and osmotic conditions. Two studies were conducted to determine the effect of stress temperatures during germination and seedling development on polyamine titers in soybean seeds. Three germination temperatures, 25, 30, and 36 0C were used in the first study to evaluate their influence on changes in polyamine concentrations in soybean seeds germinated at ...

Glutamate-1-Semialdehyde Aminotransferase Activity During Tomato Fruit Development And Ripening, Richard Edward Finger Jan 1997

Glutamate-1-Semialdehyde Aminotransferase Activity During Tomato Fruit Development And Ripening, Richard Edward Finger

Retrospective Theses and Dissertations

Glutamate-1-semialdehyde aminotransferase (GSAT) is a key enzyme in chlorophyll biosynthesis and is a logical point to control chlorophyll loss during development in fruits. The objective of this research was to measure the activity of GSAT throughout development and ripening of the tomato fruit and compare this activity to chlorophyll concentration in fruits at the same time intervals. GSAT activity was also characterized in immature tomato fruits, and its activity was measured in tomato organs. An optimum pH of 7.0, a maximum velocity (V[subscript max]) of 2.3 nmol/g of tissue, and a K[subcript m] of 119 ...

Estimation Of Starch In Plant Tissue , Robert Delafield Powell Jan 1950

Estimation Of Starch In Plant Tissue , Robert Delafield Powell

Retrospective Theses and Dissertations

The various factors affecting the estimation of starch by determining the glucose formed by acid hydrolysis following enzymatic hydrolysis have been studied. The effect of grinding of the plant material was shown to be important. Insufficient grinding leads to low values in starch, and grinding in the ball mill caused a breakdown of starch, and probably of non-starch interfering substances, to more soluble material;Gelatinization is necessary to extract starch from plant tissue. Probably vigorous conditions are not needed, but autoclaving for one hour at 15 pounds had no detrimental effect on starch recovery;Salivary diastase is preferred to taka-diastase ...
