Apparent Recombination or Gene Conversion in the Ribosomal ITS Region of a Flammulina (Fungi, Agaricales) Hybrid

Karen W. Hughes and Ronald H. Petersen

Department of Botany, University of Tennessee at Knoxville

Internally transcribed spacer (ITS) regions of ribosomal DNA are widely used in reconstructing phylogenies at lower taxonomic levels (see, e.g., Vilgalys and Sun 1994Citation ; Baldwin et al. 1995Citation ). Ribosomal genes are tandemly repeated, and the paralogs are usually identical due to a poorly understood process of concerted evolution. Proposed mechanisms of concerted evolution include unequal crossing over (Schlotterer and Tautz 1994Citation ) and biased gene conversion (Hillis et al. 1991Citation ; Linares, Bowen, and Dover 1994Citation ). Within-individual diversity for the ribosomal ITS region has been observed and has in some cases been attributed to hybridization (Sang, Crawford, and Stuessy 1995Citation ; Hugall, Stanton, and Moritz 1999Citation ).

This report documents an apparent natural hybridization event between two species of Flammulina (F. velutipes and F. rossica) . . . [Full Text of this Article]
