Creator:: Choi, Daram
Abstract:: Black stain root disease (BSRD) is a vascular wilt disease of conifers caused by three varieties of the native, insect-vectored fungal pathogen, Leptographium wageneri (L. wageneri var. wageneri, L. wageneri var. ponderosum, and L. wageneri var. pseudotsugae). Although morphological, physiological, and ecological characteristics differ among the three varieties of L....

Creator:: Scrivani, James V.
Abstract:: Forests are some of the most ecologically diverse and dense habitats on the planet. Research shows that the endophyte community, or the fungi, bacteria, and viruses within a forest ecosystem is highly diverse. Fungal endophytes are defined as fungi that live within the tissues of host plants. Relationships between fungal...

Creator:: Cauldron, Nicholas C.
Abstract:: Oomycete and fungal pathogens threaten food, fiber, and forests around the world. With climate change, these pathogens are expected to emerge more frequently. Evolution can facilitate their emergence through mechanisms such as mutations that change or expand host range. Characterizing evolutionary mechanisms in plant pathogens will contribute to our ability...

Creator:: Thapliyal, Mrinal
Abstract:: Coastal Douglas-fir (Pseudotsuga menziesii var. menziesii), a keystone species in the Pacific Northwest, relies on symbioses with microorganisms to obtain nutrients, potentially defend against pathogens, and perform a variety of other tasks. Two of the tree’s primary fungal symbionts are foliar epiphytes and endophytes, which reside on the exterior or...

Creator:: Buckner, Jacob G.
Abstract:: This study is believed to be the first of its kind to characterize culturable fungal endophytes from the wood of Populus trichocarpa, and to examine the potential of inducible resistance and secondary chemistry as specific host factors that shape fungal endophytic communities in wood. To do so, more than seventy...

Creator:: Hill, Ryan J.
Abstract:: The European hazelnut (Corylus avellana L.) is a diploid (2n = 2x = 22) tree crop important to the economy of Oregon’s Willamette Valley, where 99% of hazelnut production in the United States is located. Corylus avellana exhibits sporophytic self-incompatibility (SSI), controlled by a single S-locus with at least 33...

Creator:: Hatwal, Shikhar
Abstract:: Bacterial endophytes have the potential to confer benefits to Douglas-fir ( Pseudotsuga menziesii ), for instance drought tolerance. Bacterial endophytes originating from seeds are especially important. This is because seed endophytes are more likely to be the first endophytes to get established within the young host plant. The goals of...
