Degree of genetic differentiation of the local populations of Schizophyllum commune (Agaricales, Basidiomycota) in the southern part of Kyiv

Boiko S.M.

Establishing genetic diversity of fungi is a fundamental issue related to the development of their conservation strategies. The data on genetic differentiation of the local populations of Schizophyllum commune in the southern part of Kyiv using polymorphic intracellular enzyme systems are provided. In total, fifteen allozymes were identified in three experimental populations of the fungus for four enzyme systems. It was demonstrated that heterozygote deficiency exists for most of the studied loci at the population level (Fis = 0.390). The results show a high flow of genes between experimental populations (Nm = 7.12) and a significant contribution of the Amy2 locus to this index. A relationship between the genetic component and geographic coordinates of the samples was not established. Low level of genetic differentiation provides evidence in favor of fungal dispersal mostly by the spore mass. Thus the studied local populations belong to a single natural population.
