Report from the Mycological Society

In July, one of our own, Dr. Roo Vandegrift, went to the annual Mycological Society of America (MSA) meeting, held just outside of Atlanta, Georgia, in the college town of Athens. He went to learn what others in the field are up to, and present work from the BioBE Center. Roo live-tweeted most of the talks he went to; you can find him @MycoRoo on twitter to look back through his experience of the conference, and look up the hashtag #MSA17 or #MSA2017 to see other posts about the conference.

The meeting started with a pre-conference foray: a group of nearly one hundred mycologists loaded into three packed busses and went out to Unicoi State Park for a 3.5 mile hike; collecting mushrooms, ascomycetes, and plant pathogenic fungi all the way. It has apparently been a particularly wet summer in Georgia so far, and the fungal diversity on display was astonishing, particularly coming from Oregon, where our summers are dry and a bit mycologically deprived.

On Monday morning, the day started with the Presidential Address from outgoing president, Dr. Georgiana May, titled “Lucky: A career in mycology.” She gave a rolling account of a career full of lucky breaks and fortuitous moments, which she made the best possible use of with her sharp and grateful mind. She also included a number of historical anecdotes that had the audience in stitches of laughter, and sometimes on the verge of tears. She asked that the contents of her talk remain private, though, so that’s as much detail as I’ll give here.

The first session of talks that I went to was the Ecology & Conservation section, which started with Terry Henkel presenting some amazing work from his lab on the Thelephoralean ectomycorrhizal fungi of a monodominant tropical forest in the Guyana shield region of South America, and how these fungi may be involved in seedling survival and recruitment in this forest. The discussion of this system continued with the next talk in the session, from Terry’s graduate student, Carolyn Delevich, who gave a fascinating discussion of the community assembly of ectomycorrhizal fungi on the roots of these dominant Fabaceae trees, looking at the change in the community over time on the seedlings from one of these mass fruiting events.

There were a number of other excellent talks about mycorrhizal communities, highlighting the cutting edge of molecular techniques in fungal community ecology, host-associated dynamics, and spatial/temporal ecology. Dr. Alija Mujic’s talk on invasion dynamics in mycorrhizal communities of Nothofagus in Patagonia was particularly good.

At the end of that first day, Roo presented his talk: “Impacts of Weatherization on Indoor Fungal Communities“, co-authored with other BioBE personnel, as well as colleagues from the Oregon Research Institute and Northwestern University (Roo Vandegrift, Ashkaan Fahimipour, Jeff Kline, Alejandro Manzo, Dale Northcutt, Jason Stenson, Hannah Wilson, Ryann Crowley, Erica Hartmann, Deborah Johnson-Shelton, G.Z. Brown, Jessica Green, Kevin Van Den Wymelenberg). This talk debuted preliminary data from our EPA-funded study examining a multi-faceted, interdisciplinary dataset combining microbial ecology, indoor air quality, and an extensive survey detailing aspects of health and behavior. Feedback was incredibly positive and encouraging, including some really helpful feedback on biophysical explanations for observed trends in the data.

There were a handful of other talks that stood out as particularly important or impactful. Mara DeMers, from the University of Minnesota, Twin Cities, presented on endophytic fungi in prairie plants, and whether molecular OTUs (or ESVs, for that matter) correspond to species; she asks the question does it matter if they do? She was particularly vexed by the genus Alternaria, which made up most of her endophyte sequences, and appears to be non-resolvable into meaningful groupings via ITS alone — the region is so variable in this group (and other!), that the intra-strain variation is as great as the inter-strain variation, meaning that the same sequence may belong to totally different strains, while very different sequences may belong to extremely closely related individuals. This is an important caution for the field, and one we at the BioBE Center will certainly keep in mind!

Among the amazing talks, excellent company, and stimulating scientific conversations, Dr. Regine Kahmann (from Max Planck Institute for Terrestrial Microbiology) presented the the Karling Lecture, titled “Core Effectors in Smut Fungi: An Amazing Treasure Box.” This was an incredible summary of her life’s work on the molecular mechanisms underlying the pathogenicity and ecology of smut fungi (Ustilagomycota). The careful, methodical, innovative science on display during her talk was breathtaking, and an inspiration.

One other talk strikes me as worth explicit mention here: Jesse Uehling’s discussion of how to re-purpose archived data in new ways. I think there’s an important lesson here; we are generating sequence data much more rapidly than we are currently exhausting the ways that such data can be explored, and the techniques for exploring that data are evolving extremely rapidly. As Jesse says, there may be treasure in that trash!

One idea from her talk that struck me as particularly significant was that the “junk” reads from genomic assemblies are typically reads representing the microbiome of whatever organism was sequenced. It is certainly worth considering that there may be a large quantity of un-examined microbiome data available from a wide range of organisms, if we only go looking through the available raw data. And, the assembly of small bacterial genomes from mixed starting templates has been well demonstrated.

There were many other noteworthy aspects to this meeting; it is worth browsing the #MSA17 tweets if you’re interested. We hope for many more productive, fascinating meetings like this in the future!


Roo wore a different mushroom-patterned bowtie every day of the meeting. We’re not sure why he was so pleased about this.

Congratulations to Dr. Ashley Bateman on her defense, next steps!

We made sure to send her off with some Oregon memorabilia.

Last week, BioBE said good-bye and good-luck to Ashley Bateman, who successfully defended her dissertation on May 25th.  Ashley has been with the department for 6 years, as a graduate student in the Institute of Ecology and Evolution at the University of Oregon.  She worked in the labs of Drs. Jessica Green and Brendan Bohannan, studying the human skin microbiome.  Her thesis, entitled “Moving Microbes: The dynamics of microbial transfer and persistence on human skin“, will soon be available through the University of Oregon library.

Starting in 2011, Ashley has had a very distinguished graduate career; in 2012 she received a  National Science Foundation (NSF) Graduate Research Fellowship Program (GRFP) award to conduct research on the transfer of microorganisms to human skin from contact sources, in 2013 she was named Outstanding Graduate Student by the UO Institute of Molecular Biology, in 2015 she received the William R. Sistrom Memorial Scholarship Award, and in 2016 she won a scholarship from the Women in Graduate Sciences organization at UO to attend the Pacific Northwest Women in Science Retreat.  She has already co-authored a number of cutting-edge papers, including the investigation of the human microbiome cloud, a meta-analysis on the indoor microbiome, and a review on human hygiene, as well as a number of other previously published and forthcoming articles.  Ashley has also been interviewed and has contributed blog posts on the implications of her work.  From here, she is headed to the University of California, Davis, to attend law school.  BioBE is going to miss her insight, her organizational skills and attention to detail, and her welcoming personality, but we are enthusiastic about the next step in her journey!

Dr. Sue Ishaq joins the BioBE team!

Hello, readers! I’m Dr. Sue Ishaq, the newest Research Assistant Professor hire in the BioBE center at the University of Oregon.  I’ve been at the center for two weeks now, and I thought I’d introduce myself as I’ll soon be a regular contributor to the center’s research efforts and blog.  I’m a microbial ecologist with a focus on host-associated microbiomes. My baccalaureate and doctorate were both in animal science and nutrition from the University of Vermont, in Burlington.  As a Ph.D. student in the Wright Lab, my work focused on identifying and manipulating the bacteria, methanogens, and protozoa in the rumen of the North American moose.  For the past two years, I was a post-doctoral researcher at Montana State University, in Bozeman.  For one year, I was in the Department of Animal and Range Sciences performing the bioinformatic analyses for multiple host-associated and environmental projects in the Yeoman Lab.  My second year was in the Department of Land Resources and Environmental Sciences in the Menalled Lab, where I was part of a large project investigating the effect of climate change on wheat production.  For my part, this meant assessing the changes to soil bacteria over time and under different climate scenarios.

Here at the BioBE, I’ll be adding my experience in host-associated microbiomes, bacterial ecology, and health, to the growing collaborative research team.  Over the course of the summer, I’ll be writing several grants and organizing new projects that explore how building design, occupancy, pets, and human habits affect human health and the indoor microbiome.  If you happened to have been at the Health + Energy Research Consortium, held in Portland in May, you might have seen me around, and I’ll also be at the Ecological Society of America meeting in Portland, OR in August.  You can follow me on my personal blog and, of course, you can find me on the BioBE blog!
