Apple replant disease: unraveling the fungal enigma hidden in the rhizosphere.

ABSTRACT: The occurrence of apple replant disease (ARD) is closely related to the increase of soil pathogenic fungi abundance. However, the relationship between ARD and fungal community structure remains poorly understood. In this study, Illumina high-throughput sequencing was used to investigate the composition, diversity, and function of rhizosphere fungal communities associated with healthy (HRS) and diseased apple trees (DRS). Microbial taxa related to ARD were also identified. The severity of ARD varied among the sampled orchards. We found that Ascomycota was the dominant phylum in the DRS fungal taxa, and the fungal community abundance and Simpson index of DRS were significantly higher than those of HRS. Cluster and FUNGuild database analyses revealed significant differences in the relative ab
