The effects of abscisic acid on gene expression during wheat germination

Creator:: Ballo, Barbara
Abstract:: Germination of immature (Stage III) and mature (Stage V) wheat (Triticum aestivum L. var. Chinese Spring and Yamhill) embryos is prevented by the inclusion of 10⁻⁴ M abscisic acid (ABA) in culture medium. In addition, Stage III embryos develop into mature embryos in culture medium containing ABA. In the absence...

Characterizing novel bacterial isolates that inhibit the growth of gall-forming phytopathogenic bacteria

Creator:: Belcher, Michael S.
Abstract:: Agrobacterium tumefaciens and Rhodococcus fascians are plant pathogenic bacteria that can induce crown and leafy galls on plants, respectively. Infection by these bacteria results in disfigured, unsellable plants, leading to significant economic losses to the nursery industry. A. tumefaciens and R. fascians are capable of infecting a broad range of...

Serpentine and non-serpentine edaphic ecology and the recovery of Lomatium cookii (Apiaceae), an endangered endemic of southwest Oregon

Creator:: Silvernail, Ian S.
Abstract:: The role of unusual geologies in plant distribution and form is well-known. Serpentine (ultramafic) soils exert a particularly strong influence on plants, as evidenced by a high level of endemism and the morphological and physiological traits displayed in adaptation to the extraordinary chemistry of these substrates. Adaptation may lead to...

Susceptibility of Pacific yew (Taxus brevifolia Nutt.) to Phytophthora lateralis

Creator:: Murray, Marion S.
Abstract:: In 1991 Pacific yew (Taxus brevifolia Nutt.) was reported as a new host for Phytophthora lateralis Tucker and Milbrath which is an aggressive root rot pathogen thought previously to be specific to Port-Orford-cedar. This study was designed to compare the pathogenicity of P. lateralis on the two hosts, and to...

Honeggeriella complexa gen. et sp. nov., a heteromerous lichen from the lower cretaceous of Vancouver Island (British Columbia, Canada)

Creator:: Matsunaga, Kelly K. S., Stockey, Ruth A., and Tomescu, Alexandru M. F.
Abstract:: • Premise of the study: Colonists of even the most inhospitable environments, lichens are present in all terrestrial ecosystems. Because of their ecological versatility and ubiquity, they have been considered excellent candidates for early colonizers of terrestrial environments. Despite such predictions, good preservation potential, and the extant diversity of lichenized...

Annual cycles of ecological disturbance and recovery underlying the subarctic Atlantic spring plankton bloom

Creator:: Behrenfeld, Michael J., Doney, Scott C., Lima, Ivan, Boss, Emmanuel S., and Siegel, David A.
Abstract:: Satellite measurements allow global assessments of phytoplankton concentrations and, from observed temporal changes in biomass, direct access to net biomass accumulation rates (r). For the subarctic Atlantic basin, analysis of annual cycles in r reveals that initiation of the annual blooming phase does not occur in spring after stratification surpasses...

Phylogenetic insights into the correlates of dioecy in meadow-rues (Thalictrum, Ranunculaceae)

Creator:: Soza, Valerie L., Brunet, Johanne, Liston, Aaron, Smith, Patricia Salles, and Di Stilio, Veronica S.
Abstract:: Numerous studies have examined the evolution of sexual systems in angiosperms, but few explore the interaction between these and the evolution of pollination mode. Wind pollination is often associated with unisexual flowers, but which evolved first and played a causative role in the evolution of the other is unclear. Thalictrum,...

Genome-Wide Profiling and Analysis of Arabidopsis siRNAs

Creator:: Kasschau, Kristin D., Fahlgren, Noah, Chapman, Elisabeth J., Sullivan, Christopher M., Cumbie, Jason S., Givan, Scott A., and Carrington, James C.
Abstract:: Eukaryotes contain a diversified set of small RNA-guided pathways that control genes, repeated sequences, and viruses at the transcriptional and posttranscriptional levels. Genome-wide profiles and analyses of small RNAs, particularly the large class of 24-nucleotide (nt) short interfering RNAs (siRNAs), were done for wild-type Arabidopsis thaliana and silencing pathway mutants...

Identification of Myosin XI Receptors in Arabidopsis Defines a Distinct Class of Transport Vesicles

Creator:: Peremyslov, Valera V., Morgun, Eva A., Kurth, Elizabeth G., Makarova, Kira S., Koonin, Eugene V., and Dolja, Valerian V.
Abstract:: To characterize the mechanism through which myosin XI-K attaches to its principal endomembrane cargo, a yeast two-hybrid library of Arabidopsis thaliana cDNAs was screened using the myosin cargo binding domain as bait. This screen identified two previously uncharacterized transmembrane proteins (hereinafter myosin binding proteins or MyoB1/2) that share a myosin...
