Molecular studies on the evolution and systematics of fungi have been established primarily based on the neutral theory by analyzing neutral mutations in some defined segments of housekeeping genes as genetic markers. Such an approach is, however, hardly applicable for analyzing ancient evolutionary radiations. In the present study, we looked for DNA sequences characterizing higher taxa, and discovered a unique macroevolutionary genomic marker, megB1, that specifies the phylum Basidiomycota. megB1 is an approximately 500-bp DNA element, which is defined by terminal sequences and five internal segments conserved throughout the phylum. megB1 resides on the rDNA intergenic spacer 1 (IGS1) from 27 species of 10 Basidiomycota genera examined. While megB1 was not found in IGS1 from the other 92 species of the 27 Basidiomycota genera, several genera representing them carry megB1 in some other genomic regions. No known taxonomic criteria fit into the classification on the basis of whether megB1 resides on rDNA. Neighbor-joining analysis of the megB1 sequence, however, properly assigned species to their respective genera. Thus far, megB1 has not been found in any genomic or genetic databases currently available for other phyla. These results suggest that megB1 may have emerged upon the occurrence of Basidiomycota, and that this phylum evolved thereafter leaving this element conserved throughout their further differentiation. megB1 may be a novel genomic marker useful in the analysis of ancient through the latest evolutionary radiation in Basidiomycota.
