Journal ArticleDOI
Oomycete species associated with soybean seedlings in North America-part I: Identification and pathogenicity characterization
J. Alejandro Rojas,Janette L. Jacobs,Stephanie A. Napieralski,Behirda Karaj,Carl A. Bradley,Thomas Chase,Paul D. Esker,Loren J. Giesler,Doug Jardine,Dean K. Malvick,Samuel G. Markell,Berlin D. Nelson,Alison E. Robertson,John C. Rupe,Damon L. Smith,Laura Sweets,Albert Tenuta,Kiersten A. Wise,Martin I. Chilvers +18 more
TL;DR: This study provides a comprehensive characterization of oomycete species present in soybean seedling roots in the major production areas in the United States and Ontario, Canada and provides a basis for disease management and breeding programs.
Journal ArticleDOI
Oomycete Species Associated with Soybean Seedlings in North America-Part II: Diversity and Ecology in Relation to Environmental and Edaphic Factors.
J. Alejandro Rojas,Janette L. Jacobs,Stephanie A. Napieralski,Behirda Karaj,Carl A. Bradley,Thomas Chase,Paul D. Esker,Loren J. Giesler,Doug Jardine,Dean K. Malvick,Samuel G. Markell,Berlin D. Nelson,Alison E. Robertson,John C. Rupe,Damon L. Smith,Laura Sweets,Albert Tenuta,Kiersten A. Wise,Martin I. Chilvers +18 more
TL;DR: It is suggested that oomycete species composition across geographical locations of soybean production is affected by a combination of environmental and edaphic conditions.
Journal ArticleDOI
Development and Application of qPCR and RPA Genus- and Species-Specific Detection of Phytophthora sojae and P. sansomeana Root Rot Pathogens of Soybean
TL;DR: Multiplex qPCR and isothermal RPA (recombinase polymerase amplification) assays were developed using a hierarchical approach to detect Phytophthora spp.
Journal ArticleDOI
Fungal Endophytes of Populus trichocarpa Alter Host Phenotype, Gene Expression, and Rhizobiome Composition.
Hui-Ling Liao,Gregory Bonito,J. Alejandro Rojas,J. Alejandro Rojas,Khalid Hameed,Steven H. Wu,Christopher W. Schadt,Jessy Labbé,Gerald A. Tuskan,Francis Martin,Igor V. Grigoriev,Rytas Vilgalys +11 more
TL;DR: Metatranscriptomic studies revealed that these fungi impacted rhizophytic and endophytic activities in P. trichocarpa and induced shifts in soil and root microbial communities.
Journal ArticleDOI
Ectomycorrhizal Plant-Fungal Co-invasions as Natural Experiments for Connecting Plant and Fungal Traits to Their Ecosystem Consequences
Jason D. Hoeksema,Colin Averill,Jennifer M. Bhatnagar,Edward R. Brzostek,Erika Buscardo,Ko-Hsuan Chen,Ko-Hsuan Chen,Hui-Ling Liao,Laszlo Nagy,Nahuel Policelli,Joanna Ridgeway,J. Alejandro Rojas,Rytas Vilgalys +12 more
TL;DR: Hypotheses on how effects of introduced and invasive EM fungi may depend on interactions between soil N availability in the exotic range and EM fungal traits are developed and tested.
