An Experiment To Test For Rapid Evolution In An Introduced Ectomycorrhizal Symbiosis, Valerie Rewa
An Experiment To Test For Rapid Evolution In An Introduced Ectomycorrhizal Symbiosis, Valerie Rewa
Honors Theses
The rapid evolution of introduced ectomycorrhizal-plant partnerships is an under- explored topic that may have immense impacts on ecosystems around the world. This experiment sought to identify and quantify this evolution and its impacts on both fungal colonization as well as plant growth. I used a laboratory experiment to analyze these factors in native and exotic genotypes of Suillus cothurnatus and Pinus species. Much of the data was not able to be collected, but that which was did not support the presence of rapid evolution in the mutualistic partnership. Pine species was seen to have a significant effect on plant …
A Perspective On Fungal-Algal Symbioses Through Comparative Dual-Transcriptomics Of "Franken-Lichen" Tissues And "Microbial Speed-Dating" Assays, Michael Clear
Electronic Theses and Dissertations
Mutualistic symbioses are ubiquitous and among one of the most crucial biological interactions. Some of the most iconic examples are fungal-photoautotroph mutualisms such as lichens, mycorrhizal-plant, and endophytic fungal-plant symbioses. Yet little is understood about the earliest origins of such microbial mutualisms, and more precisely, how they relate to the origin of land plants. The study of the evolution of fungal-photoautotroph symbioses is often limited to comparative genomic techniques due to the few genetic tools available for studying extant interactions. Recent work suggests that extant fungal-plant interactions have their origins in fungal-algal associations.In Chapter 1, I review the evolution of …
