Structure and expression of two Populus trichocarpa homologs of the floral homeotic gene AGAMOUS

Creator:: Brunner, Amy Marie
Abstract:: Because of their small genomes, facile clonal propagation, fast growth, and susceptibility to Agrobacterium transformation, poplars (genus Populus) are widely considered model systems for the application of molecular genetics and biotechnology in forestry. However, a major concern over commercial use of genetically engineered trees is the release of transgenes into...

Perception and reproductive response of common beans (Phaseolus vulgaris L.) to photoperiod

Creator:: Privett, Diane Winters
Abstract:: Three Oregon snap beans were tested for photoperiodic response on the basis of their overall flowering patterns. Oregon 1604 and Oregon 4848 showed the same cumulative flowering curves and percent pod set under both 11 hour SD and 16 hour LD photoperiods. Under SD, Oregon 2065 produced a similar flowering...

Architecture, size, and reproduction in plants : a pollination study of Mertensia ciliata (James) G. Don

Creator:: Geber, Monica
Abstract:: I experimentally test the hypothesis that the potential for selfing increases with plant size in Mertensia ciliata (Boraginaceae), a self-compatible, profusely-flowering perennial. This follows from the premises that 1) pollen dispersal by pollinators between flowers is limited, and 2) individual pollinators, in this study bumblebees, will visit more flowers per...

Genetic requirements for the assembly and cell-to-cell movement of the beet yellows virus

Creator:: Alzhanova, Dina
Abstract:: Beet yellows virus (BYV) is a filamentous, positive-strand RNA virus that belongs to the family Closteroviridae. BYV particles encapsidate a 15.5 kb RNA and posses complex polar architecture. A long virion body is formed by the major capsid protein(CP), whereas the minor capsid protein (CPm) assembles a short tail that...
Resource Type:: Dissertation
Full Text:: movement machinery of BYV is the most complex among plant viruses. Extensive mutational analysis of CP

Factors affecting conifer regeneration and community structure after a wildfire in western Montana

Creator:: Toth, Barbara L.
Abstract:: A severe wildfire burned 454 hectares of a second-growth Douglas-fir forest in 1977 on a north-facing slope in Pattee Canyon, near Missoula, Montana. The slope was aerially seeded with a grass mixture, from which Dactylis glomerata established best. Community structure, conifer regeneration, and the impact of the seeded grass on...
Resource Type:: Masters Thesis
Full Text:: , conifer regeneration, and the impact of the seeded grass on the plant community were evaluated with two

Life-history and physiological trade-offs to reproduction of invasive and noninvasive Rubus

Creator:: McDowell, Susan C.
Abstract:: The goal of this dissertation was to improve our understanding of the physiology and life-history of invasive plants and of the mechanisms underlying life-history trade-offs. I compared invasive and noninvasive species of Rubus (blackberry) that grow together in the Pacific Northwest. Three hypotheses were investigated: (1) Invasive Rubus have higher...

The influence of distance and floral phenology on pollen gene flow and mating system patterns in a coastal Douglas-fir seed orchard

Creator:: Erickson, Vicky J., 1955-
Resource Type:: Masters Thesis

Reproduction, demography, and habitat characterization of Astragalus peckii (Fabaceae), a rare central Oregon endemic

Creator:: Martin, Elizabeth F.
Abstract:: With little previous research on Astragalus peckii (Fabaceae), a state-listed Threatened species in Oregon, I investigated three facets of its biology which are integral to the conservation and management of the species. First, a four-year demographic study of two large populations revealed increasing population growth at one site (Chiloquin) and...
Resource Type:: Dissertation

Mineral assessment of open range livestock production on the Warm Springs Indian Reservation

Creator:: Brummer, Fara Ann
Abstract:: The Warm Springs Reservation is located in central Oregon. Livestock production consists of beef (commercial with an Angus, Horned Hereford base) and roping (Corriente and Longhorn) cattle and horses that forage most of the year on the open range within reservation boundaries. Forage consists of annual and perennial grasses and...
Resource Type:: Masters Thesis
Full Text:: (LxU). Plant samples were also collected in October 2008 and May 2009 to determine mineral content
