 @article{powell_jacobson_natvig_2007, title={Ancestral polymorphism and linkage disequilibrium at the het-6 region in pseudohomothallic Neurospora tetrasperma}, volume={44}, ISSN={["1096-0937"]}, DOI={10.1016/j.fgb.2007.04.010}, abstractNote={In species of Neurospora, non-self recognition is mediated by at least 11 heterokaryon (het) incompatibility loci. Previously, we identified ancient allelic variation at het-c in pseudohomothallic N. tetrasperma, which confirmed outcrossing in this species. Here, we report distinct ancestral alleles at het-6 and un-24, two closely linked genes with het incompatibility function in N. crassa. The pattern of variation at het-6 and un-24 in N. tetrasperma is similar to that observed for N. crassa, where two ancestral allele specificities exist for each locus, Oak Ridge (het-6OR, un-24OR) and Panama (het-6PA, un-24PA). Only het-6OR/un-24OR and het-6PA/un-24PA allele combinations have been observed. The absence of recombinant haplotypes (e.g., het-6OR/un-24PA) appears to derive from an ancestral chromosomal rearrangement that limits recombination. Allelic variation at het-6 and un-24 in N. tetrasperma provides further evidence of outcrossing in this predominantly selfing species and indicates that selection maintains ancient allelic diversity at het loci.}, number={9}, journal={FUNGAL GENETICS AND BIOLOGY}, author={Powell, Amy J. and Jacobson, David J. and Natvig, Donald O.}, year={2007}, month={Sep}, pages={896–904} }
