| 英文摘要 | The basidiomycete Lepiota cristata (Agaricales) is among the most widely distributed saprophytic Mushrooms in the Northern Hemisphere. It's commonly found on humus-rich soil in a variety of terrestrial habitats, from roadsides to forest floors. In this study, we analyzed 47 isolates of the L. cristata species complex from China using DNA sequences from three loci (the internal transcribed spacer region or ITS, the inter-genic spacer or IGS, and the mitochondrial small ribosomal subunit RNA gene or mtSSU rRNA). Our analyses identified abundant sequence variation and potentially divergent lineages within L. cristata for each of the three loci. Interestingly, there were significant differences among the three gene genealogies and our linkage disequilibrium analyses identified unambiguous evidence of recombination, hybridization and/or incomplete lineage sorting. Furthermore, several sequence types were shared among isolates from diverse geographic locations for each of the three analyzed loci. Our population genetic analyses indicated limited evidence for genetic differentiation among geographic populations, suggesting that long-distance gene flow might be common among geographic populations of this species in China. We discuss the implications Of Our results with regard to the Population biology and taxonomy of this widely distributed but under-studied species. |
