Irrigation water and plant density effects on the epidemiology of aerial stem rot of potatoes

Creator:: Cappaert, Marlys R.
Abstract:: Field plots of cv. Russet Burbank potatoes from a single seedlot were established at four sites over two seasons (1985-86) in two locations in Oregon to determine the role of water-borne inoculum of Erwinia carotovora in plant infection. One site at each location was irrigated from a surface-water source and...

An Exploration of the Ecological and Geographical Variability of Rhizopus microsporus Clinical and Environmental Isolates

Creator:: Stairs, Brandon S.
Abstract:: Rhizopus microsporus is a globally ubiquitous opportunistic human and plant pathogen that is known to harbor endosymbiotic bacteria. Differences between populations of clinical and environmental R. microsporus isolates have yet to be assessed on a global scale. Whole-genome sequence data were used to explore fungal biology and to assess potential...

Genome-wide profiling of Populus small RNAs

Creator:: Klevebring, Daniel, Street, Nathaniel R., Fahlgren, Noah, Kasschau, Krisitin D., Carrington, James C., Lundeberg, Joakim, and Jansson, Stefan
Abstract:: Background: Short RNAs, and in particular microRNAs, are important regulators of gene expression both within defined regulatory pathways and at the epigenetic scale. We investigated the short RNA (sRNA) population (18-24 nt) of the transcriptome of green leaves from the sequenced Populus trichocarpa using a concatenation strategy in combination with...

The Role of Plant-soil Feedback in the Invasion of Brachypodium sylvaticum in Douglas-fir Forests

Creator:: Esterson, Andrew
Abstract:: Invasive plants have the capacity to transform landscapes and alter ecosystem function, causing significant economic and ecological damage. These effects include displacement and reduction of native flora and fauna, altered fire regimes, modification of biotic and abiotic soil properties, as well as local, regional, and global economic impacts. With such...

Molecular and genetic analyses of genome variability in Ustilago hordei

Creator:: Agnan, Jacqueline
Abstract:: Pulsed-field gel electrophoresis (PFGE) of the strains representing the 14 races of U. hordei, the causal agent of covered smut on barley, revealed extensive polymorphism in chromosome length and number. The purpose of this study was to determine by two approaches the exact chromosome number for each U. hordei race,...

Expression Levels of the γ-Glutamyl Hydrolase I Gene Predict Vitamin B9 Content in Potato Tubers

Creator:: Goyer, Aymeric
Abstract:: Biofortification of folates in staple crops is an important strategy to help eradicate human folate deficiencies. Folate biofortification using genetic engineering has shown great success in rice grain, tomato fruit, lettuce, and potato tuber. However, consumers’ skepticism, juridical hurdles, and lack of economic model have prevented the widespread adoption of...

Mitigating cyanobacterial harmful algae blooms : the role of plant humics

Creator:: Theis, Susan A. F.
Abstract:: Cyanobacterial harmful algae blooms (cyanoHABs) are a growing concern worldwide due to damage of ecosystems and threats to human health. Previous research indicates that plant humics from aquatic and wetland vascular plants are effective inhibitors of cyanobacterial metabolism and growth and may be useful as control agents for mitigating cyanoHABs....

Response to fenamiphos, extraction techniques and population dynamics of Pratylenchus penetrans on western Oregon red raspberry

Creator:: Lolas, Mauricio
Abstract:: The effects of fenamiphos on soil and root populations of Pratylenchus penetrans were evaluated in four red raspberry cv. Willamette fields in Northwestern Oregon. Field 1 was a silty clay loam with 53% organic matter (OM). Field 2 and 3 were silty loam soils with 3.25 and 2.55% OM, respectively...

Contracting nucleolar vacuoles in somatic tobacco cells growing in microcultures

Creator:: Johnson, John Morris
Abstract:: Contracting nucleolar vacuoles are a general and consistent feature of somatic tobacco cells growing in microcultures. Nucleolar vacuoles were studied in cells from callus tissues of two single-cell clones, H-196 and H-239, of hybrid tobacco (Nicotiana tabacum X N. glutinosa). Vacuoles periodically contracted either completely or incompletely, apparently releasing a...

Use of simultaneous analyses to guide fossil-based calibrations of Pinaceae phylogeny

Creator:: Gernandt, David S., Magallon, Susana, Lopez, Gretel Geada, Flores, Omar Zeron, Willyard, Ann, and Liston, Aaron
Abstract:: Uncertainties in the age and phylogenetic position of Pinaceae fossils present significant obstacles to our understanding of the timing of diversification in the family. We demonstrate that simultaneous phylogenetic analyses of chloroplastDNA(matK and rbcL) and nonmolecular characters that include both extant genera and a limited number of fossil taxa provide...
