Fungicide and fertilizer-mediated changes in prairie plant-foliar fungal endophyte interactions
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2025-02-04 without embargo terms

The influence of intraspecific variation in host plants on arthropod and fungal endophyte communities
… trees (Sequoia sempervirens) can affect foliar fungal communities. In Chapter Three, I determine the relative influence of host-associated variation, abiotic conditions, and interspecific microbial interactions for shaping fungal endophyte communities in spotted locoweed (Astragalus …

Effect of Alternative Management Practices and the Fungal Endophyte (Epichloë festucae var. lolii) on Improving the Longevity of Perennial Ryegrass (Lolium perenne L.) in Minnesota
… research project studied the effect of the fungal endophyte Epichloë festucae var. lolii on the freezing tolerance of a wide array of perennial ryegrass germplasm. Our results showed no direct effect of endophyte on freezing tolerance of perennial ryegrass; however, there was consistent …

Seasonal Variation in Swainsonine and Endophyte Concentrations of Undifilum oxytropis in Different Plant Parts of Oxytropis sericea
… neurological disease caused by swainsonine. The fungal-endophyte Undifilum oxytropis, found in locoweed plant species of Astragalus and Oxytropis spp., is thought to be responsible for the synthesis of swainsonine. It has been shown that the swainsonine alkaloid and fungal endophyte are not …

Host Specificity, Negative Feedbacks, and Pathogen Defense in the Plant Phyllosphere Microbiome
… explored whether host specificity influences fungal endophyte community structure in plant leaves across several ecotypes of switchgrass (Panicum virgatum) and across 19 plant species within the Asteraceae family. In these works, I found contrasting results for the importance of host …

Diversity and spatial distribution of fungal endophytes in a Eucalyptus grandis tree
… sequencing of the barcode amplicons of all the fungal isolates present in the plants from the total DNA of the plant. Secondly, conventional DNA bar-coding of was done of fungal endophyte isolates. Isolates of the Botryosphaeriaceae family of latent endophytic pathogens were further …

The Evaluation of the Endophytic Mycobiome of Magnolia grandiflora
… occupying internal tissues of plants are called endophytes. Fungal endophytes are of major importance because they exist in the healthy tissues of all terrestrial plants and have in some cases been shown to contribute to the health of their plant hosts. They are also important because some fungi …

Isolating and Identifying Fungal Endophytes from Roots of Rare Orchid Cypripedium arietinum in Grand Sable Dunes, Michigan
… little research on this species’ root associated fungal endophytes. This new population estimate allows the ethical, destructive sampling required to shed light on root associated symbionts and further successful preservation and restoration of the species. Samples were collected of current year’s …

A molecular characterization of the fungal endophytes within the needles of ponderosa pine (Pinus ponderosa)
<p>"Fungal endophytes (microbial fungi that live in plant tissues without causing disease) are ubiquitous in plants studied to date. Many conifers host endophytes that produce important bioactive secondary metabolites. While the endophytes in Pinus ponderosa roots have been studied, the endophyte …

Induced defenses in apple fruits: linking fruit chemistry, quality, and plant-insect-microbe interactions
… Ultimately, phenolic defenses were induced by fungal damage primarily in ripe pulp tissues, where there was also a positive relationship between fungal endophyte and phenolic diversity, supporting a broad hypothesis that chemical diversity may increase with biotic diversity. Additionally, two …

Effects of coastal dynamics on colonization of Louisiana wetland plants by fungal endophytes
… the effects of stress and disturbance on fungal endophyte diversity and composition in obligate wetland plants in southeast Louisiana. I explored two types of endophytes: root and foliar. Each of these groups is known to live within apparently healthy host plants without causing symptoms …

Consumption of Endophyte Infected Fescue During Gestation in Beef Cows
… stresses is attributed to the presence of a fungal endophyte. Unfortunately, this endophyte also adversely affects cattle production. Cows consuming the ergot alkaloids produced by these endophytes can exhibit decreased feed intake, growth performance, organ vasoconstriction, and increased …

Influence of forage characteristics on grazing behavior of weaned steers
For Virginia, the primary forage base is endophyte-infected tall fescue (Schedonorus phoenix (Scop.) Holub). However, the decreased animal performance and disorders caused by the presence of the fungal endophyte Neotyphodium coenophialum reduces its suitability for many forage-livestock producers. …

Functional diversity of fungal symbiont communities and the impact of biotic and abiotic factors on their composition and assembly
… dominant members of the plant microbiomes, the fungal endophytes, the main goal of this research was to investigate how the ecological context affect microbial symbiont community structure and assembly. To do that, first, I investigated patterns of carbon resource use and growth of fungal …

Characterization of tomato root-endophytic fungi and analysis of their effects on plant development, on fruit yield and quality and on interaction with the pathogen Verticillium dahliae
Non-mycorrhizal fungal endophytes are able to colonize internally roots without causing visible disease symptoms establishing neutral or mutualistic associations with plants. These fungi known as non-clavicipitaceous endophytes have a broad host range of monocot and eudicot plants and are highly …

Beneficial Fungal Secretome and Synthetic Consortia to Improve Soybean Growth During Drought Stress
… Our goal was to build a naturally occurring fungal synthetic community (FunSynCom) to improve growth and drought resilience in soybeans. In this study, we isolated, identified, and characterized a set of fungal endophytes from the rhizosphere of halophytic plants during a low-tide summer with …
