Creating Useful and Useable Climate Tools for Sagebrush Land Management Through Scientist and Manager Collaboration

Creator:: Brown, Melanie
Abstract:: The sagebrush ecosystem, home to numerous plant and animal species including big sagebrush (Artemisia tridentata) and the endemic greater sage-grouse (Centrocercus urophasianus), has endured fragmentation and degradation of both quantity and quality due to the cumulative and synergistic relationships between an abundance of individual disturbances including grazing, invasive annuals and...

Temperature Dependence of Cu₃₋xSb₁₋[subscript y]M[subscript y]S₄ (M=Sn,Ge) Resistivity and Thermopower

Creator:: Mutch, Joshua
Abstract:: An experimental apparatus is modified to allow measurements of the Seebeck coefficient and resistivity to be taken simultaneously. This apparatus is designed for bulk and thin film samples between temperatures of 10 K and 300 K. The apparatus is constructed such that these simultaneous measurements do not interfere with each...

Structural and functional analysis of the finished genome of the recently isolated toxic Anabaena sp WA102

Creator:: Brown, Nathan M., Mueller, Ryan S., Shepardson, Jonathan W., Landry, Zachary C., Morré, Jeffrey T., Maier, Claudia S., Hardy, F. Joan, and Dreher, Theo W.
Abstract:: Background: Very few closed genomes of the cyanobacteria that commonly produce toxic blooms in lakes and reservoirs are available, limiting our understanding of the properties of these organisms. A new anatoxin-a-producing member of the Nostocaceae, Anabaena sp. WA102, was isolated from a freshwater lake in Washington State, USA, in 2013...

Age structure, developmental pathways, and fire regime characterization of Douglas-fir/western hemlock forests in the central western Cascades of Oregon

Creator:: Tepley, Alan J.
Abstract:: Descriptions of the fire regime in the Douglas-fir/western hemlock region of the Pacific Northwest traditionally have emphasized infrequent, predominantly stand-replacement fires and an associated linear pathway of stand development, where all stands proceed along a common pathway until reset by the next fire. Although such a description may apply in...

Biomass and community structure of sporocarps formed by hypogeous ectomycorrhizal fungi within selected forest habitats of the H. J. Andrews Experimental Forest, Oregon

Creator:: Luoma, Daniel L.
Abstract:: This study characterizes the production of hypogeous sporocarps (broadly referred to as truffles) by ectomycorrhizal fungi within Douglas-fir dominated forests that are considered typical of those found on the west slopes of the central Cascade mountains in Oregon. Three aspects of sporocarp production are addressed: 1) the distribution of total...

Diverse Evolutionary Trajectories for Small RNA Biogenesis Genes in the Oomycete Genus Phytophthora

Creator:: Bollmann, Stephanie R., Fang, Yufeng, Press, Caroline M., Tyler, Brett M., and Grünwald, Niklaus J.
Abstract:: Gene regulation by small RNA pathways is ubiquitous among eukaryotes, but little is known about small RNA pathways in the Stramenopile kingdom. Phytophthora a genus of filamentous oomycetes, contains many devastating plant pathogens, causing multibillion-dollar damage to crops, ornamental plants, and natural environments. The genomes of several oomycetes including Phytophthora...

A Phytophthora sojae effector suppresses endoplasmic reticulum stress-mediated immunity by stabilizing plant Binding immunoglobulin Proteins

Creator:: Jing, Maofeng, Guo, Baodian, Li, Haiyang, Yang, Bo, Wang, Haonan, Kong, Guanghui, Zhao, Yao, Xu, Huawei, Wang, Yan, Ye, Wenwu, Dong, Suomeng, Qiao, Yongli, Tyler, Brett M., Ma, Wenbo, and Wang, Yuanchao
Abstract:: Phytophthora pathogens secrete an array of specific effector proteins to manipulate host innate immunity to promote pathogen colonization. However, little is known about the host targets of effectors and the specific mechanisms by which effectors increase susceptibility. Here we report that the soybean pathogen Phytophthora sojae uses an essential effector...

Two Theobroma cacao genotypes with contrasting pathogen tolerance show aberrant transcriptional and ROS responses after salicylic acid treatment

Creator:: Fister, Andrew S., O'Neil, Shawn T., Shi, Zi, Zhang, Yufan, Tyler, Brett M., Guiltinan, Mark J., and Maximova, Siela N.
Abstract:: Understanding the genetic basis of pathogen susceptibility in various crop plants is crucial to increasing the stability of food, feed, and fuel production. Varietal differences in defence responses provide insights into the mechanisms of resistance and are a key resource for plant breeders. To explore the role of salicylic acid...

Efficient disruption and replacement of an effector gene in the oomycete Phytophthora sojae using CRISPR/Cas9

Creator:: Fang, Yufeng and Tyler, Brett M.
Abstract:: Phytophthora sojae is an oomycete pathogen of soybean. As a result of its economic importance, P. sojae has become a model for the study of oomycete genetics, physiology and pathology. The lack of efficient techniques for targeted mutagenesis and gene replacement have long hampered genetic studies of pathogenicity in Phytophthora species....

Protocol: transient expression system for functional genomics in the tropical tree Theobroma cacao L.

Creator:: Fister, Andrew S., Shi, Zi, Zhang, Yufan, Helliwell, Emily E., Maximova, Siela N., and Guiltinan, Mark J.
Abstract:: Background: Theobroma cacao L., the source of cocoa, is a crop of significant economic value around the world. To facilitate the study of gene function in cacao we have developed a rapid Agrobacterium-mediated transient genetic transformation protocol. Here we present a detailed methodology for our transformation assay, as well as...
