Diversity of basidiomycetes in michigan agricultural soils.

ABSTRACT: We analyzed the communities of soil basidiomycetes in agroecosystems that differ in tillage history at the Kellogg Biological Station Long-Term Ecological Research site near Battle Creek, Michigan. The approach combined soil DNA extraction through a bead-beating method modified to increase recovery of fungal DNA, PCR amplification with basidiomycete-specific primers, cloning and restriction fragment length polymorphism screening of mixed PCR products, and sequencing of unique clones. Much greater diversity was detected than was anticipated in this habitat on the basis of culture-based methods or surveys of fruiting bodies. With "species" defined as organisms yielding PCR products with > or =99% identity in the 5' 650 bases of the nuclear large-subunit ribosomal DNA, 241 "species" were dete
