However, few studies have simultaneously examined microbial community variation in multiple plant-associated habitats across multiple sites; thus, it is unclear what scales and filters are most important in shaping whole-plant microbiome diversity. To address this, we characterized fungal communities associated with switchgrass (Panicum virgatum L.) leaves, roots, and soils within and across 14 stands spanning mountain to coastal ecoregions of North Carolina. Niche differences at small scales (i.e., less than half a kilometer) best explained variation in fungal communities. However, the specific environmental drivers of fungal community composition differed for leaves, roots, and soils. Leaf and root fungi were both affected by plant height, whereas soil fungi were controlled by stand age. Different soil properties were important for fungi in all plant-associated habitats: K, P, and pH for leaves; clay, Mn, and pH for roots; and clay, dissolved organic carbon, total inorganic N, and Cu for soils. Climate and spatial variables were not significant, further supporting the key role of plant and soil properties. Advances such as these will help us explain, predict, and manipulate microbial assemblages that support plant growth in managed and natural systems. }, number={1}, journal={PHYTOBIOMES JOURNAL}, publisher={Scientific Societies}, author={Lee, Marissa R. and Hawkes, Christine V}, year={2021}, pages={69–79} } @misc{hestrin_lee_whitaker_pett-ridge_2021, title={The Switchgrass Microbiome: A Review of Structure, Function, and Taxonomic Distribution}, volume={5}, ISSN={["2471-2906"]}, DOI={10.1094/PBIOMES-04-20-0029-FI}, abstractNote={ Switchgrass (Panicum virgatum L.) has been championed as a promising bioenergy crop due to its high productivity across a wide environmental range. The switchgrass microbiome—including bacteria, archaea, fungi, and other microbiota inhabiting soil and plant tissues—can influence plant function substantially. We conducted a review of the literature investigating switchgrass microbiome structure, key functional roles, and taxa isolated from field-grown plants. Although site conditions and plant compartment (i.e., location within shoots, roots, or root-influenced soil) appear to be the strongest drivers of switchgrass microbiome structure, the microbiome is also shaped by climate, season, and host genotype. Studies comparing across plant species show that the switchgrass microbiome is more similar to the microbiomes of other perennial plants than to the microbiomes of annual plants. Members of the switchgrass microbiome confer several benefits to their host. Most notably, mycorrhizal fungi can increase plant biomass many-fold, associative nitrogen-fixing bacteria can provide a substantial portion of the plant’s nitrogen demand, and fungal endophytes can improve plant tolerance to drought. Although the fungi and bacteria cultured from switchgrass represent only a portion of the microbiome, these serve as a valuable resource for researchers interested in investigating functional outcomes of the switchgrass microbiome. We highlight areas where additional research is necessary for a more comprehensive understanding of switchgrass microbiome structure, function, and potential to enhance sustainable bioenergy production. Key gaps include the role of understudied organisms (e.g., viruses, microeukaryotes, and nonmycorrhizal fungi), multitrophic relationships, mechanisms underpinning switchgrass–microbiome interactions, and field-scale validation of experimental findings. }, number={1}, journal={PHYTOBIOMES JOURNAL}, author={Hestrin, Rachel and Lee, Marissa R. and Whitaker, Briana K. and Pett-Ridge, Jennifer}, year={2021}, pages={14–28} } @article{lee_hawkes_2021, title={Widespread co-occurrence of Sebacinales and arbuscular mycorrhizal fungi in switchgrass roots and soils has limited dependence on soil carbon or nutrients}, volume={3}, ISSN={["2572-2611"]}, url={https://doi.org/10.1002/ppp3.10181}, DOI={10.1002/ppp3.10181}, abstractNote={Societal Impact Statement}, number={5}, journal={PLANTS PEOPLE PLANET}, publisher={Wiley}, author={Lee, Marissa R. and Hawkes, Christine V}, year={2021}, month={Sep}, pages={614–626} } @article{oberle_lee_myers_osazuwa-peters_spasojevic_walton_young_zanne_2020, title={Accurate forest projections require long-term wood decay experiments because plant trait effects change through time}, volume={26}, ISSN={["1365-2486"]}, DOI={10.1111/gcb.14873}, abstractNote={Abstract}, number={2}, journal={GLOBAL CHANGE BIOLOGY}, author={Oberle, Brad and Lee, Marissa R. and Myers, Jonathan A. and Osazuwa-Peters, Oyomoare L. and Spasojevic, Marko J. and Walton, Maranda L. and Young, Darcy F. and Zanne, Amy E.}, year={2020}, month={Feb}, pages={864–875} } @article{lee_oberle_olivas_young_zanne_2020, title={Wood construction more strongly shapes deadwood microbial communities than spatial location over 5 years of decay}, volume={22}, ISSN={["1462-2920"]}, DOI={10.1111/1462-2920.15212}, abstractNote={Summary}, number={11}, journal={ENVIRONMENTAL MICROBIOLOGY}, author={Lee, Marissa R. and Oberle, Brad and Olivas, Wendy and Young, Darcy F. and Zanne, Amy E.}, year={2020}, month={Nov}, pages={4702–4717} }
