The local populations of the fungus Schizophyllum commune Fr. as drivers of its biodiversity
(Sciendo (De Gruyter), 2021-12-11) Boiko, Sergiy
Changes that occur on the local level can explain the processes on the population level and, at the same time, are the driving force of species adaptation. This manuscript reports data about genetic diversities of the fungus Schizophyllum commune on the level of a local population. Objects of the study were dicarious cultures of S. commune collected from 38 basidiocarps grown on the territory of Holosiivskyi National Nature Park, Lysa Hora Regional Landscape Park and Feofaniya forest parcel (Ukraine). Results showed similarity of genetic variability of S. commune in different local populations. The heterozygote deficiency of some loci that was discovered might have resulted from new forms of allozymes that have not become widespread or due to small population sizes. The degree of differentiation of genes between local studied populations was moderate due to the high flow of genes. The absence of spatial structuration of genotypes is established, and the Mantel test showed a lack of interconnection between the genetic component and the geographical coordinates of the samples. It has been suggested that wind direction and terrain are the factors that influence the genetic structure of local populations.
