Genome sequences of Phytophthora enable translational plant disease management and accelerate research

Creator:: Grünwald, Niklaus J.
Abstract:: Des séquences entières ou partielles de génomes deviennent de plus en plus accessibles. En ce qui concerne plusieurs systèmes plante-agent pathogène, nous abordons l’ère du recéquençage du génome. Les premiers génomes de Phytophthora, P. ramorum et P. sojae, ont été disponibles à partir de 2004, suivis de près par celui...

Early Selection for Improving Volume Growth in Coastal Douglas-fir Breeding Programs

Creator:: Ye, T. Z. and Jayawickrama, K. J. S.
Abstract:: Measurements on growth traits up to 41 years of age from 68 progeny sites in eight first-generation breeding zones of coastal Douglas-fir (Pseudotsuga menziesii [MIRB.] FRANCO var. menziesii) in the US Pacific Northwest were used to investigate age trends of genetic parameters and to determine optimum age of selection. Heritabilities...

Diversity of Foliar Phytophthora Species on Rhododendron in Oregon Nurseries

Creator:: Knaus, B. J., Fieland, V. J., Graham, K. A., and Grünwald, N. J.
Abstract:: The genus Phytophthora contains some of the most notorious plant pathogens affecting nursery crops. Given the recent emergence of the sudden oak death pathogen Phytophthora ramorum, particularly in association with Rhododendron spp., characterization of Phytophthora communities associated with this host in nursery environments is prudent. Many taxa may present symptoms...

Poppr: an R package for genetic analysis of populations with clonal, partially clonal, and/or sexual reproduction

Creator:: Kamvar, Zhian N., Tabima, Javier F., and Grünwald, Niklaus J.
Abstract:: Many microbial, fungal, or oomcyete populations violate assumptions for population genetic analysis because these populations are clonal, admixed, partially clonal, and/or sexual. Furthermore, few tools exist that are specifically designed for analyzing data from clonal populations, making analysis difficult and haphazard. We developed the R package poppr providing unique tools...

Spatial and Temporal Analysis of Populations of the Sudden Oak Death Pathogen in Oregon Forests

Creator:: Kamvar, Z. N., Larsen, M. M., Kanaskie, A. M., Hansen, E. M., and Grünwald, N. J.
Abstract:: Sudden oak death caused by the oomycete Phytophthora ramorum was first discovered in California toward the end of the 20th century and subsequently emerged on tanoak forests in Oregon before its first detection in 2001 by aerial surveys. The Oregon Department of Forestry has since monitored the epidemic and sampled...

First Report of the EU1 Clonal Lineage of Phytophthora ramorum on Tanoak in an Oregon Forest

Creator:: Grünwald, N. J., Larsen, M. M., Kamvar, Z. N., Reeser, P. W., Kanaskie, A., Laine, J., and Wiese, R.
Abstract:: Initially reported in California as the causal agent of sudden oak death (SOD), efforts to limit spread of Phytophthora ramorum in Oregon natural forests have concentrated on quarantine regulations and eradication of the pathogen from infested areas. P. ramorum has four clonal lineages: NA1; NA2; EU1; and EU2 (Grünwald et...

Identification and distribution of mating-type idiomorphs in populations of Podosphaera macularis and development of chasmothecia of the fungus

Creator:: Wolfenbarger, S. N., Twomey, M. C., Gadoury, D. M., Knaus, B. J., Grünwald, N. J., and Gent, D. H.
Abstract:: Podosphaera macularis, the causal agent of hop powdery mildew, is known to produce chasmothecia (formerly cleistothecia) in eastern North America and Europe. Ascocarps have not yet been reported from the Pacific Northwestern region of North America. Reasons for the apparent absence of chasmothecia in the Pacific Northwest were unknown. This...

Loop-mediated isothermal amplification for detection of the tomato and potato late blight pathogen, Phytophthora infestans

Creator:: Hansen, Z. R., Knaus, B. J., Tabima, J. F., Press, C. M., Judelson, H. S., Grünwald, N. J., and Smart, Christine D.
Abstract:: Aims: To design and validate a colorimetric loop-mediated isothermal amplification assay for rapid detection of Phytophthora infestans DNA. Methods and Results: Two sets of loop-mediated isothermal amplification (LAMP) primers were designed and evaluated for their sensitivity and specificity for P. infestans. ITSII primers targeted a portion of the internal transcribed...

First Report of Phytophthora occultans Causing Root and Collar Rot on Ceanothus, Boxwood, Rhododendron, and Other Hosts in Horticultural Nurseries in Oregon, USA

Creator:: Reeser, P. W., Sutton, W., Hansen, E. M., Goheen, E. M., Fieland, V. J., and Grünwald, N. J.
Abstract:: Dead and dying Ceanothus sanguineus, C. velutinus, and C. integerrimus plants grown in a native plant nursery in Oregon for landscape restoration were reported in 2011. Plants were wilted with stem lesions above necrotic roots. Using selective media (Hansen et al. 2012), twelve similar Phytophthora isolates were obtained. DNA sequences...
