Welcome to the Kennedy Lab!
The research in our lab focuses on a broad range of questions regarding the ecology and evolution of plant-microbe interactions, particularly those involving symbiotic fungi and bacteria. This work integrates across multiple disciplines: mycology and microbiology, ecology and evolution, and molecular biology and biochemistry. We combine field sampling and experiments with greenhouse and growth chamber studies to examine how both biotic and abiotic factors infuence the structure and functioning of fungal, bacterial, and plant communities.
What's new in the lab?
Our new paper on how melanin in mycorrhizal fungal necromass affects microbial decomposer structure (both fungi and bacteria) is accepted in Journal of Ecology - congrats Chris!
Our commentary of the new paper by Leho Tedersoo and colleagues about the use of PacBio for metabarcoding of fungi is accepted at New Phytologist - congrats Zewei and Lauren!
Lauren, Chris, Craig, Caroline, Luke, and Caroline all presented at ESA 2017 in Portland, OR. A great showcase of the diversity of research in our lab. Lotus presented her work at ICOM9 in Prague, Czech Republic and was awarded the Harley medal for outstanding student presentation - congrats Lotus!
A sad and happy good bye to two great members of the Kennedy lab - Obi Wamuo and Caroline Daws. Obi was a superstar undergrad in the lab this summer and Caroline was an oustanding first year grad student. All the best at U Chicago and Stanford, respectively.
Just had a great visit for our collaborators in Norway from University of Olso and Norwegian Life Sciences University. Havard, Line, Ynvgild, Luis, and Sunil all visited the SPRUCE site in northern Minnesota and learned Chris' jedi ways with fungal necromass generation first hand.
Our collaboration with the Knights lab comparing closed reference, open reference, and de novo clustering for fungal HTS datasets is accepted at New Phytologist - check it out here. Congrats to Lauren and Zewei on the Kennedy lab side and Gabe on the Knights lab side - a truly team effort.
Amanda is making great progress on generating Suillus genomes - our first from the lab, S. tomentosus, is officially out. A very fun collaboration with Nhu Nguyen (U Hawaii), Sunny Liao (U Florida), and Rytas Vilgalys (Duke U) - thanks NSF!
Lauren's lead on the effects of fungal wood endophytes of decomposer community structure and functioning is accepted at Functional Ecology - congrats Lauren!
Nico Benucci for Michigan State is visiting the lab to help harvest the first round of our truffle competition experiment. Not only is he an expert on truffles, but he is a great cook too! Thanks so much for coming across the lake for a really fun and productive visit.
Our first efforts to do high throughput sequencing with PacBio are submitted to the UMGC - thanks to Chris for his GenoFest win and Ben Auch for lots of help with library prep.
Erin submits a UROP to fund summer research on fungal necromass decomposition - fingers crossed! (March update - UROP funded - congrats Erin, very excited for the summer).
Double congrats to Chris for winning 4 PacBio cells worth of sequencing at the UMGC GenoFest and to Caroline for winning a Crosby fellowship to help cover her field research in summer 2017.
Lotus won "Outstanding Student Oral Presentation" at the MSA meeting in Berkeley this summer - congrats!
Chris and Luke gave presentations at the ESA meeting in an organized oral session of mycorrhizal fungi.
Undegrad and recent grads Michelle, Alex, Eva, Erin, and Louis did lots of excellent research in the lab this summer.
Peter attended a workshop in Santa Barbara focused on building a fungal traits database - stay tuned on updates for that.
It looks FUNGuild is getting more attention as a community resource as evidenced by inclusion talks at both the ESA and MSA meetings (yeah!). 2017 will include greater database coverage - new additions of soft rot fungi and dung saprotrophs this summer - and the linking FUNGuild to the UNITE database.
Collaboration with the Schilling lab at UMN continues - see the lab publications page for the link about functional roles of endophytes as priority wood colonizers!
The first paper of the Suillus-Pinaceae grant is in press at Mycologia - a massive ITS-based Suillus phylogeny - congrats Nhu!
Lots of good stuff happening in the lab recently - a couple of long-term projects just had papers accepted/published (see lab publications page).
Lotus passed her qualifying exam - she is officially onto Ph.D. candidacy!
Michelle Coblens joined the lab as a summer research assistant. She was an undergraduate at Macalester College and is teaming up with Chris on a wide range of fungal ecology projects this summer.
Chris, Louis, and Peter deployed nearly 1000 ingrowth bags into the SPRUCE experiment to look at the dynamics of mycorrhizal fungi necromass decomposition under different global change scenarios.
Chris and Peter got seed grant funding from the Norwegian Centennial Chairs Program to collaborate with Havard Kauserad, Line Nybakken, and Mikael Olson on a new project. Here is the abstract:
This project will investigate how plant-associated symbiotic fungi influence the storage of carbon in boreal forest soils. The work will specifically focus on how changes in soil fertility and climatic conditions influence the decomposition of dead fungal and plant biomass. Researchers at the University of Minnesota (UM), University of Olso (UIO), and Norwegian Life Sciences University (NMBU) will collaborate on a set of field-based observational and experimental studies located in both Norway and the United States. The research will leverage experimental infrastructure present in both countries and involve scientists with synergistic expertise in fungal and plant ecology, ecosystem biogeochemistry, molecular microbial identification, and bioinformatics. Collectively, the project will provide new insights into the role of plant-associated symbiotic fungi in carbon sequestration processes and how changes in resource availability and environmental conditions may mediate the belowground response of boreal forest ecosystems to climate change.
Chris received the Mycological Society of America's Fungal Forest Ecology Post-doc Award to support his current research on the 'Gadgil effect' at Cedar Creek - congrats Chris!
Eva Carlson presented a poser of her UROP project on Quercus fine root morphology at the Univeristy of Minnesota Undergraduate Research Symposium.
Caroline Daws will be joining the lab in the fall as an incoming Ph.D. student in the Ecology, Evolution, and Behavior graduate program - welcome Caroline! Craig See will also be joining the lab as a shared incoming Ph.D. student with Sarah Hobbie in EEB - welcome Craig!
Amanda Certano has rejoined the lab as the technician on the Suillus NSF grant project - welcome back Amanda!
Lauren has just received a NSF post-doc fellowship to study the long-term effects of nitrogen deposition on fungal communities in midwest forests. She will be co-advised with Jessica Gutknecht and use fungal collections at the Bell Museum of Natural History - congrats Lauren!
Nhu has just accepted a tenure-track faculty position at the University of Hawaii - congrats Nhu!
Our collaboration with Francois Rineau and other European colleagues on the protein degradation abilities of ectomycorrhizal fungi was accepted for publication at Applied and Environmental Microbiology. Here is the .pdf - congrats Francois!
Chris' review on the decomposition dynamics of ectomycorrhizal fungal necromass is now out in Soil Biology and Biochemistry. Nice work Chris - excited to launch new necromass work at SPRUCE and beyond.
Eva Carlson won a UROP award to work with Luke, Matt Kaproth, Jeannine Cavender-Bares, and Peter examining variation in root traits across a diverse suite of temperate and tropical Quercus species - congrats Eva!
The book Mycorrhizal Networks has been published, which contains a chapter by Peter, Jen Walker (former post-doc) and Laura Bogar (former undergraduate student) on the ecology of non-networking hosts. In our chapter, we focused on Alnus-Frankia-ECM interactions and if you are unfamiliar with the lab's previous work on the topic, this chapter is a good summary.
Lots of good stuff. Lauren Cline joined the lab as a post-doc - welcome Lauren! Two visiting scholars are also working with the lab - Drs. Luke McCormack and Ying Han. Excited to have both at UMN. The 'Gadgil Effect' review paper lead by Chris was published. Click here to read it. Just a few weeks later, Peter's collaboration with researchers at Oregon State University and the University of British Colombia on vertical niche partitioning among ectomycorrhizal fungi was published. Click here to read it.
Many members of the lab attended ICOM and gave both oral and poster presentations - well done Lotus, Chris, and Nhu!
FUNGuild (an open-access and open-annotation tool to parse community fungal datasets into ecological guilds) is out and in press - click here for the publication.
Congrats to undergrads Louis M, Cher Ling T, and Léonce S-N for successful poster presentations. Lotus received an NSF-GRFP! Congrats Lotus!! Nhu just published a paper on maximizing ecological signal vs. noise in high throughput sequencing datasets. Read it here. Chris just published a commentary in New Phytologist about moving fungal ecology beyond the black box. Read it here.
