Abstract
Description
The soil mycobiome is an important part of the numer-
ous biogeochemical processes taking place in the soil. Its activ-
ity and diversity are influenced by many factors, including soil
moisture. In this study, the effect of a 14-day simulated flood on
the mycobiome of three different Fluvisols in microcosm experi-
ment was assessed using next-generation sequencing. The results
obtained showed that excessive moisture alters the structure of
the mycobiome and the amounts of pathogenic, parasitic, and en-
dophytic fungi. Among others, an increase in the occurrence of
saprotrophic fungi of the genera Trichoderma, Talaromyces, and
Schizothecium was noted. At the same time, the study showed
a decrease in the abundance of arbuscular mycorrhizal fungi
from the phylum Glomeromycota and Mucoromycota as a result
of flooding. In addition, the structure of the soil mycobiome has
been shown to be closely related to soil type – statistically sig-
nificant correlations of individual fungal genera with the clay and
silt or sand content of the soil were obtained. Future research on
the soil mycobiome under flooding conditions may help to under-
stand changes in soil biogeochemical processes following flood-
ing, the occurrence of which is increasing with climate change.
