Population genetics of Fomitopsis rosea– a wood‐decay fungus of the old‐growth European taiga
The genetic structure of the wood‐decay fungus Fomitopsis rosea (Alb. et Schw. Fr.) Karst is presented for populations sampled in Russia, Sweden and Finland. A total of 11 variable arbitrary primed (AP)–PCR markers were found to be segregated in a 1:1 ratio. The genotype for each fruiting body was i...
