Biosynthesis of blasticidin S : mechanistic and stereochemical investigations

Creator:: Prabhakaran, P. C.
Abstract:: Feeding of [3-¹³C, 2-¹⁵N]arginine, 38a, unequivocally established that the β- arginine moiety of blasticidin S, 1, was formed from α-arginine by an intramolecular migration of the α-amino group to the β- position. Further feedings using chirally deuteriated arginines 38e and 38f revealed that the aminomutase process occurred with inversion of...

Height-diameter and volume equations, growth intercept and needle length site quality indicators, and yield equations for young ponderosa pine plantations in Neuquén, Patagonia, Argentina

Creator:: Gonda, Hector Eduardo
Abstract:: Ponderosa pine (Pinus ponderosa Dougl. ex Laws.) is the most widely planted species in the Patagonian Andes region of Argentina for economic development. However, information on site quality and yield is so limited that potential forest investors and managers do not have a reliable basis on which to make sound...

The population dynamics and growth of salmonberry (Rubus spectabilis) and thimbleberry (Rubus parviflorus)

Creator:: Maxwell, Bruce D.
Abstract:: Salmonberry (Rubus spectabilis) and thimbleberry (Rubus parviflorus) are clonal shrub species common to reforestation sites in the Oregon Coast Range. These species have economic importance, because they reduce conifer seedling growth and survival. A population modeling approach was used to facilitate study of the biology of these species and to...

Repeated sequences associated with inversions and length mutations in the chloroplast genomes of Pseudotsuga and Pinus

Creator:: Hipkins, Valerie D.
Abstract:: To help understand the mechanisms of conifer chloroplast genome evolution, we characterized the nucleotide sequences of Douglas-fir (Pseudotsuga menziesiz) and Monterey pine (Pinus radiata) chioroplast DNA that are associated with a length mutation hotspot and inversion. The chloroplast DNA ofthese two conifers are characterized by shared large inversions that are...

Population dynamics of three early seral herb species in Pacific Northwest forests

Creator:: Hanson, D. Eric
Abstract:: I investigated the population dynamics of fireweed (Epilobium angustfolium), foxglove (Digitalis purpurea) , and woodland groundsel (Senecio sylvaticus) to understand their colonization, persistence, and extirpation in Pacific Northwest Douglas-fir forests. Factors affecting the species' frequency and abundance in forest communities were evaluated. Their population dynamics were modeled and field experiments...

Evaluation of rabbit breeds and crosses for overall commercial productivity

Creator:: Lukefahr, Steven D.
Abstract:: In two breeding experiments, straightbred and crossbred rabbits were evaluated for performance characters relating to reproduction, disease resistance, growth and carcass quality. In the first experiment, New Zealand White CNN) and Flemish Giant (FG) straightbreds and FG sire x (Florida White-New Zealand White dam) terminal-crossbreds (TX) were involved. Reproductive performance...

The effect of prepartum anionic diets on cortisol, adiponectin, and tumour necrosis factor-α expression at varying levels of body mass index in preparturient dairy cows: implications for insulin resistance

Creator:: Puntenney, Steven B.
Abstract:: Twenty-six Holstein and 18 Jersey multiparous cows in a randomized block design were assigned by calving date and breed to a non-anionic prepartum diet (CTRL) or a treatment diet containing a commercial anionic salt supplement (Animate®). Control and treatment diets were formulated to a dietary anion-cation difference (DCAD) of 21.3...

Evaluation of allelopathy as a mechanism by which buckwheat suppresses Canada thistle and its mycorrhizae

Creator:: Eskelsen, Steven R.
Abstract:: Experiments were conducted to determine if allelopathy is a mechanism by which buckwheat interferes with a) the growth of Canada thistle and/or b) mycorrhizae colonization in Canada thistle roots. In a competition experiment, buckwheat plant biomass was only affected by the intraspecific competition from other buckwheat plants and not by...
