NSF-DBI-10-46052: “Dimensions of Biodiversity: Deconstructing diversity and ecosystem function at multiple spatial and genetic scales in a keystone plant-microbe symbiosis” PIs: Tom Bruns, John W Taylor, and Kabir Peay).   This collaborative project between 5 labs (Berkeley, Stanford, Boston Univ. and Duke) utilizes next-generation sequencing techniques to investigate diversity of mycorrhizal fungi associated with pines (Pinus spp.).  Aims of the project include  (1)  the first continental scale perspective of ectomycorrhizal communities associated with pines,  (2) establish patterns of gene flow and selection for several key fungal taxa across North America, (3) measure variation in functional enzyme production, and  (4) use RNA based metagenomics to measure the full spectrum of  functional trait expression on individual mycorrhizal root tips.  By doing so, this project aims to synthesize links among taxonomic, genetic and functional diversity of fungi across dominant pinaceous ecosystems in North America.  Web site:

JGI/EMSL Collaborative Science Project (proposal 48480) Integrated genomic/transcriptomic/secretomic study of plant-fungal interactions between pines and their symbiotic ectomycorrhizal fungi in the mushroom genus Suillus. PIs: Rytas Vilgalys, Duke University (with H.L. Liao, Jennfer Talbot, Tom Bruns, Sara Branco, John Taylor and Kabir Peay). This follow-up to our DOB project above will support an ‘omics’ approach to study of symbiotic interactions between pines (Pinus spp.) and their ectomycorrhizal fungi (EMF) in the genus Suillus. We are developing the Pine-Suillus symbiosis as a model for understanding EME function across diverse pine-dominated forests of North America, including how symbiotic fungi utilize and sequester plant-derived carbon. As the dominant community of symbiotic microbes in forest soils, EMF atransfer nutrients to tree roots and receive plant carbon in exchange. Suillus species are keystone members of the EMF community that exhibit strong hostspecific associations with different Pinus spp. This project will combine study of the fungal genome (by JGI), the mycorrhizal transcriptome (by JGI) and proteome/metabolome (by EMSL) of symbiotic fungal/plant pairs to identify genes/transcripts/proteins/metabolites associated with fungal-plant interaction, nutrient acquisition strategies of Suillus, and host-specificity between species of Suillus and Pinus. By simultaneously exploring the biochemistry of the plant-fungal interface and the fungal-soil interface, results from this study will address the full capacity of Pinus and Suillus species to influence carbon cycling and energy flow in ecosystems.   (

PMI: Plant Microbe Interfaces. This project is a Foundational Genomics Scientific Focus Area supported by the U.S. Department of Energy.  The project examines tghe dynamic interface  between plants, microbes and their environment, with a focus on defining the genetic bases of molecular communication between Populus and its microbial consortia. The project  is based at the Oak Ridge National Laboratory, with collaborators at the University of Washington, Duke University, and INRA – Nancy (France).   The Vilgalys lab is using both culture-based and culture-independent methods (nextgen sequencing) to identify the dominant species of symbiotic fungi within the Populus rhizosphere. To date, we have isolated over 2000 strains representing about 100 fungal taxa that serve many different ecological roles as saprobes, endophytes, pathogens, and mutualistic symbionts. Many of the fungi isolated by our project have been found to have a growth-promotion effect on Populus and other plant hosts, though its molecular basis is still not fully understood (a patent disclosure has been filed). Representative strains of over 20 fungal species have been submitted for genome sequencing by the JGI, providing a genome-based assessment of their metabolic functioning.   We we currently investigating function of different root-associated fungi with Populus i metagenomics (RNAseq, metabolomics, and proteomics).

ZyGoLife.  Zygomycete Genealogy of Life (ZyGoLife).  PI’s: Jason Stajich (UC Riverside), Joseph Spatafora (OSU), Timothy James (Mich.), Robert Roberson (ASU), Mary Berbee (UBC), Tom Taylor (KU), Merlin While (Boise St.), Rytas Vilgalys (Duke), Matt Smith and Gerry Benny (UF), Nicolas Corradi (UO) and Kerry O’Donnell (USDA).  Zygomycetes comprise ancient lineages of Kingdom Fungi that include plant symbionts, animal and human pathogens, and decomposers of a wide variety of organic compounds. Zygomycetes are thought to be among some of the first terrestrial organisms and facilitated the origin of land plants.  They represent one of the earliest origins of multicellularity and the filamentous body plan and polar cell growth that characterize most species of fungi.  They are also used in numerous industrial processes (e.g., organic acid production) and fermentation of foods (e.g., tempeh, soy sauce).  Despite these critical ecological roles and morphological innovations, and importance to human civilization, little is understood about their evolutionary relationships.  ZyGoLife will resolve the evolutionary relationships through integration of numerous types of data including genome sequencing and analyses, discovery and description of zygomycete fossils, development of enhanced tools for detecting zygomycetes in the environment, and elucidation of novel morphological characteristics through state-of-the-art bioimaging.  In addition, the project will develop educational resources for the general public for this important but poorly known group of Kingdom Fungi.  Web site:
