Stochastic and deterministic drivers of seasonal variation of fungal community in tobacco field soil.

ABSTRACT:

Background

The soil fungal community plays an important role in global carbon cycling and shows obvious seasonal variations, however, drivers, particularly stochastic drivers, of the seasonal variation in the fungal community have never been addressed in sufficient detail.

Methods

We investigated the soil fungal community variation between summer growing (SG) and winter fallow (WF) stage, through high throughput sequencing of internal transcribed spacer (ITS) amplicons. Subsequently, we assessed the contribution of different ecological processes to community assembly using null-model-based statistical framework.

Results

The results showed that the fungal community diversity decreased significantly after tobacco cropping in the SG stage and the composition showed a cle
