A genetic linkage map of the basidiomycete Coprinus cinereus was constructed on the basis of the segregation of 219 RAPD markers, 28 RFLP markers and the A and B mating-type loci among 40 random basidiospore progeny from a single cross between a wild-type homokaryon, KF(3)#2, and an AmutBmut strain, #326. Thirteen linkage groups covering a total of 1346cM were identified and correlated to the 13 chromosomes of this fungus by hybridization of RFLP and RAPD marker probes to CHEF blots. These probes also revealed chromosome length polymorphisms (CLP), which could be associated with haplotype plots of the progeny. The average kb/cM ratio in this cross was approximately 27.9kb/cM. The AmutBmut strain undergoes sexual development without mating, because of mutations in both A and B mating-type loci, and has been used to identify mutations affecting developmental processes such as dikaryosis, fruit body morphogenesis, and meiosis. The markers in the map, especially the RAPD ones, would facilitate mapping of genes responsible for such mutations induced in the AmutBmut strain.
