- Abstract
The study on microbial community composition in rhizosphere soils surrounding dillerent order roots is ol great significance for understanding the interactions between roots and microbes. Using Illumina Miseq sequencing technology, this study analyzed the dillerences ol lungal community structure in bulk soils and rhizosphere soils surrounding different root orders ol poplar (Populus X euramericana 'Neva') tree. The microbial species annotation showed that 128, 124, 130 and 101 lungal genera were classified in the rhizosphere soils around 1 - 2 order roots (R1), 3 order roots (R2), 4-5 order roots (R3) and in the bulk soils (NR), respectively. The dillerences ol present lungal genera indicated a selectivity mechanism driving lungal community assembly in poplar rhizosphere soils. There were seven lungal genera with more than 1% ol relative abundance in rhizosphere soils. Trichoderma was the dominant lungal genus in R1. Trichosporon and Aspergillus were the dominant lungal genera in R2 and R3, respectively. Alpha (α) diversity indices showed that the lungal diversity was signilicantly dillerent among root orders. Specilically, the diversity ol soil lungal community in the rhizosphere soils around lower order roots was signilicantly higher than that ol higher order roots (P<0.05). Beta (P) diversity indices showed that the dissimilarity ol lungal community composition increased along with the root orders. All these results implied the dillerent composition and structure ol fungal community are closely related with the function ol line root orders.
