Abstract |
Little is known about the distribution of fungal communities
with soil depth on relatively large scales. In this study, typical
paddy soils in three regions (Hailun, Changshu, and Yingtan)
from north to south China were selected to investigate the
vertical distribution (0-100 cm) of the fungal community by
Illumina MiSeq sequencing, and to identify the main factors
influencing the fungal community distribution. The results
indicated that the structure of the soil fungal community
changed significantly with region and soil depth. Soil fungal
taxa such as Zygomycota, Glomeromycota, Saccharomycete,
Kazachstania, Mortierella, Massariosphaeria, Hypholoma, and
Zopfiella were enriched at depths of 0–20 cm, whereas Dothideomycetes,
Microbotryomycetes, Tremellomycetes, Sporobolomyces,
Cryptococcus, Rhodotorula, Fusarium, and Pyrenochaetopsis
had high relative abundances at 80–100 cm.
Variance partitioning analysis indicated that the geographic
distance contributed more to the fungal community variation
than environmental variables on a large scale. In addition,
soil total carbon and nitrogen contents were the main
environmental factors driving the vertical distribution of the
fungal community in paddy soils. |
