Role of GacSA Two-component System and Bacterial Surface Attachment in Pseudomonas syringae Virulence

Creator:: O'Malley, Megan R.
Abstract:: Pseudomonas syringae are plant pathogenic bacteria that cause disease by rapidly multiplying within the aboveground tissues of host plants. Growth of P. syringae within plant host tissues requires the disarmament of host immune defenses that limit microbial growth. To combat host defenses, P. syringae deploys a type III secretion system...

Candidate Genes Associated with Blister Rust Resistance in Whitebark Pine (Pinus albicaulis) Revealed through de novo Transcriptome Assembly and Differential Gene Expression Analysis

Creator:: Bair, Zolton J.
Abstract:: Whitebark pine (Pinus albicaulis) is an iconic North American high-elevation tree species currently threatened by climate change, mountain pine beetle, and white pine blister rust (WPBR), a lethal disease caused by the non-native fungal pathogen Cronartium ribicola. In collaboration with the USDA Forest Service Dorena Genetic Resource Center, germplasm was...

Developing techniques for evaluating the susceptibility of root-disease resistant Port-Orford-Cedar to foliar and stem canker diseases.

Creator:: Martin, Danielle K. H.
Abstract:: Since around 1923 Port-Orford-cedar (Chamaecyparis lawsoniana (A. Murray) Parl.) has been affected by Phytophthora root disease caused by the virulent introduced pathogen Phytophthora lateralis. A systematic resistance testing and breeding program located at the USDA Forest Service Dorena Genetic Resource Center in Cottage Grove, Oregon was initiated in 1997 with...

Phylogeny, cospeciation, and host switching in the evolution of the ascomycete genus Rhabdocline on Pseudotsuga and Larix (Pinaceae)

Creator:: Gernandt, David S.
Abstract:: The relative role of cospeciation and host switching in the phylogenetic history of ascomycete foliar symbionts is addressed in the orders Leotiales and Rhytismatales, fungi associated predominantly with Pinaceae (Coniferales). Emphasis is placed on comparing the evolution of the sister genera Pseudotsuga and Larix (Pinaceae) with that of the pathogenic...

Genetic Structure in Populations of the Douglas-fir Swiss Needle Cast Fungus Nothophaeocryptopus gaeumannii

Creator:: Bennett, Patrick I.
Abstract:: The fungus Nothophaeocryptopus gaeumannii is the causative agent of Swiss needle cast (SNC), a foliar disease of Douglas-fir. Disease is characterized by premature loss of foliage and reduced growth resulting from the inhibition of photosynthesis due to the occlusion of stomata by the ascocarps of N. gaeumannii. Although the disease...

Genomic comparisons of seed-transmissible and non-seed-transmissible strains of cucumber mosaic virus

Creator:: Ried, Jeffrey L.
Abstract:: A sensitive assay for the analysis of contaminating segments in pseudorecombinants constructed from a seed-transmissible (CVM-Pg) and a non-seed-transmissible (CMV-Le) strain of cucumber mosaic virus was developed using partial RNase T₁ digestion. Isolated genomic RNA segments produced unique digestion patterns when 3'- end labeled, treated with RNase T₁, and subjected...

The detection of ilarvirus (subgroup B) by enzyme-linked immunosorbent assay

Creator:: McMorran, Jeffrey P.
Abstract:: The reliability and sensitivity of enzyme-linked immunosorbent assay (ELISA) in the detection of ilarvirus (isometric labile ringspot virus) subgroup B and prune dwarf virus (PDV) isolates in Prunus and Malus species has been well established. To use this technique in large scale virus indexing programs more information was required on...

Photoacclimation in Marine Phytoplankton Under Various Light and Nutrient Regimes and the Resulting Effect on Photosynthetic Electron Flow and Chlorophyll Fluorescence Transients

Creator:: Brown, Matthew B.
Abstract:: Photoacclimation is the process by which plants and phytoplankton adjust the concentration and composition of their photosynthetic machinery (i.e. their photoacclimation state) in response to changes in their light or nutrient environment. The purpose of photoacclimation is to balance the rate at which light energy is absorbed with the energetic...
