The Oregon State University Fungal Herbarium’s Curator Dr. Jessie Uehling recently received a grant from the United States Forest Service, Northern Research Station to accession over 35,000 truffle fungi into the OSC collection. Oregon State University herbarium already houses approximately 15,000 collections from the Trappe-Castellano herbarium. The fungi were collected, curated, and preserved by world renowned truffle experts Drs. James Trappe and Michael A. Castellano. Joining a long history of OSU scientists and truffle biology field leaders before them, together Drs. Trappe and Castellano collected and described over 1,000 new species and documented over 5,000 additional species from the Americas, Europe, Asia, Australia, Africa, and New Zealand. There is no greater truffle research resource in the world, and we are honored to care for the Trappe-Castellano collection and make it publicly available to researchers. This grant will enable the employment and training of under-represented minorities in the herbarium and serve as a training ground for the next generation of mycologists.

September 2020- Uehling lab is hiring!! Postdoctoral Research Position in Fungal Endosymbiont Evolutionary Genomics

Job Location: Corvallis Salary: $52,704 Applications Due: October 31st, 2020 Start Date: February 2021

The goal of this research is to investigate how endosymbiotic bacteria (EB) contribute to ecological community assembly and evolutionary diversification of early-divergent fungi in the phylum Mucoromycota. Mucoromycota are ubiquitous soil fungi with global distribution and immense ecological and economical significance. They include obligate plant mutualists (Glomeromycotina) as well as decomposers and root endophytes (Mucoromycotina and Mortiellomycotina). Mucoromycota-EB symbioses are highly coevolved, ancient, and functionally diverse. The understanding of how of and how EB shape global diversity of Mucoromycota is limited. To fill this knowledge gap, we plan to sample similar, physically isolated and leverage culture-independent approaches to test hypotheses concerning the roles of dispersal, abiotic and biotic filtering in shaping Mucoromycota communities. Further we plan to employ culture-dependent methods to evaluate the role of endobacteria in shaping Mucoromycota taxonomic diversification. We will integrate these data, allowing for inferences about the significance of EB in micro- and macroevolution of Mucoromycota.

The objectives of the position are to support research on fungal bacterial interactions in the Botany and Plant Pathology Department at Oregon State University. This position will support the lab in 1) Conducting field, lab and computational research projects on bacterial fungal symbioses; 2) Culturing and sequencing microbial diversity including fungi and bacterial symbionts; 3) Surveying the microbial communities through collecting and analyzing molecular data (i.e. DNA/RNA) 4) Developing integrative approaches to study fungal bacterial interactions in in vitro (on plates in lab) and in green house studies in plant based interaction settings; 5) Assisting in lab management, ordering materials, and training. 6) Maintaining laboratory notebooks, protocols and reagents to maximize the efficient use of resources; 7) Maintaining current knowledge of EHS & OSHA safety rules and ensure that all laboratory personnel are informed and aware of all rules and regulations; 8) Generating and analyzing data and contributing writing to scientific manuscripts; 9) provides educational and outreach activities to describe the research to the K-12 level education system in Oregon.

Position Duties

SUMMARY: This position will support the soil microbiology and ecology programs that 1) surveys the microbial communities through collecting and analyzing field samples (i.e. soils and plant biomass); 2) utilizes clearing and competition assays to evaluate the functional repercussions of fungal bacterial symbioses using transcriptomics, metabolomics, and proteomics; 3) develops integrative approaches to analyze several sources of genomics data sets; 4) disseminates the research findings to the public and industries through extension action.

Minimum/Required Qualifications Ph.D. in molecular biology, bioinformatics, microbial ecology, evolutionary biology, microbiology, or plant-fungal-bacterial interactions. Experience in computational biology, generating genomics data sets, programming preferably in Python and R, Mycology/Bacteriology/Microbiology coursework, field work, and expertise in ecological theory. Preferred (Special) QualificationsStrong writing skills and publication record, public speaking experience, working knowledge of Microsoft Office Programs such as WORD, EXCEL, and OUTLOOK, knowledge of pacific northwest flora, fungal bacterial interactions experimental design, and microfluidics.

September 2020 – OSC receives NSF funding to digitize lichens and bryophytes

PC Richard Droker Risacolia

This project, led by Dr. Jessica Budke, director of the UT Herbarium (TENN) together with co-Principal Investigator Dr. Jessie Uehling colleagues from 25 institutions will image over 1 million lichens and bryophytes and engage countless undergraduate researchers in the OSC herbarium, and we plan to focus on offering opportunities to aid the establishment of underrepresented students in STEM!!

The project, Building a Global Consortium of Bryophytes and Lichens Keystones of Cryptobiotic Communities (GLOBAL), will enable researchers from around the world to access specimen metadata and photos of the plants.

This grant will include several novel technologies including using a Object-to-Image-to-Data approach to read and decipher information from images of specimen labels, and Artificial Intelligence to flag mis-identified specimens. We will then leverage a Crowd Sourced approach via Symbiota to aid in label transcription, providing many opportunities to engage in biodiversity research from home.

August 2020 – Biodiversity Research Collective funds OSC fungal collection!!

The OSC fungal herbarium recently teamed up with the Biodiversity Research Collective, led by Jessie Uehling to curate the macrofungal and lichen collections. We leveraged a small grant to hire talented students who replaced and labeled specimen boxes, formatted >1,200 specimen accessions into public data bases like MycoPortal. They also boxed, moved and reorganized our collection in our new building!! This exciting work will facilitate generations of future research via access to the world renowned OSC fungal collection.


April 2019 – OSU Herbarium gets funding!!

 Leptogium rivale Tuck.

April 2019 Dr. Bruce McCune secures $200,000 in funding for the curation of the OSU lichen collection together with Shirley Tucker. Efforts will be made towards accessioning Drs. Riley and McCune’s collections and in documenting Leptogium (see above) diversity in the Pacific NorthWest. Congrats Bruce and all!!
