S-adenosylmethionine : [triangle]²⁴-sterol methyltransferase and the regulation of ergosterol biosynthesis in Saccharomyces cerevisiae

Creator:: Bailey, Richard B.
Abstract:: The inhibition of S-aden.osylmethionine: Δ²⁴-sterol methyltransferase (EC 2.1.1.41) activity by endogenous cellular components has been studied in vitro. The principal inhibitors were Na⁺ and K⁺; Cs⁺, NH₄⁺ and Li⁺ were also shown to inhibit the reaction. The inhibition by potassium cation has been studied, and we have found that energy...

Factors associated with stand establishment and subsequent grain yield of seven wheat cultivars and selected progeny (Triticum aestivum, L em thell) when grown under three diverse environments

Creator:: Vahabian, Mohammad Ali

Molecular and physiological aspects of maize embryo maturation

Creator:: White, Constance N.
Abstract:: Experiments were performed to assess regulatory factors governing maize embryo maturation and vivipary. Both visual and molecular markers of embryo development were used to examine the roles of the hormones abscisic acid (ABA) and gibberellins (GAs), as well as water stress in governing transit from early embryogeny to maturation-phase development....

Comparative sanitary and health significance of environmental and clinical Klebsiella species

Creator:: Bagley, Susan Tuck
Resource Type:: Dissertation
Full Text:: clinical and 85'7 (11/13) of the environmental strains as EC positive. There was no significant difference

Independent effects of habitat loss and fragmentation on pollination : tropical forest fragmentation alters hummingbird movements and pollination dynamics

Creator:: Hadley, Adam S.
Abstract:: A growing body of work reveals that animal-mediated pollination is negatively affected by anthropogenic disturbance. Landscape-scale disturbance results in two often inter-related processes: (1) habitat loss, and (2) disruptions of habitat configuration (i.e. fragmentation). Understanding the relative effects of such processes is critical in designing effective management strategies to limit...

Isozymic and cytological studies on populations of the introduced bee species, Megachile (Eutricharaea) rotundata and M. (Eutricharaea) apicalis

Creator:: Chen, Xiaoshe
Abstract:: Thirteen New World populations of Megachile rotundata and M. apicalis and two Old World populations of M. rotundata were analyzed at 23 enzyme loci using cellulose acetate electrophoresis. Conventional and G- or C-banded karyotypes were also examined in these populations. The principal findings are (1) No differences were found in...

Perinatal and postweaning effects of the interaction between maternal ethanol ingestion and low dietary zinc in the rat

Creator:: Yeh, Lee-chuan C.
Abstract:: This research was designed to study the perinatal and postweaning effects of the interaction between ethanol and low dietary zinc during gestation and lactation in the rat. Pregnant rats were fed liquid diets containing either 2 or 10 μg zinc/ml with or without 30% of kcal from ethanol throughout gestation...

Development and application of climate risk assessment methods for flood management systems – a study of flexibility, adaptive capacity, and robustness

Creator:: DiFrancesco, Kara N.
Abstract:: Discussions around adapting water management systems to climate change often express the need to increase the flexibility and adaptive capacity of current systems, and to implement robust strategies going forth. While these topics lie at the center of many climate change discussions, transforming adaptation recommendations into tangible tools and information...

Investigations into the physiology of nitrogen fixation : Part I. Nickel metabolism of plants and bacteria : Part II. Peroxide scavenging in soybean root nodules

Creator:: Dalton, David Andrews
Abstract:: PART I. The concentration of nickel in some soils may be insufficient to meet the requirements of enzymes such as urease in soybeans and hydrogenase in Rhizobium. Nickel availability in soils was examined by measuring microbial urease activity in soils which were treated with glucose and urea. Supplemental nickel was...
