The diversity of endophytic bacteria was revealed in tree peony by using 16S-ribosomal RNA gene Illumina amplicon sequencing。. The diversity of endophytic bacteria was revealed in tree peony

PCR-based Illumina was applied to reveal the diversity of endophytic bacteria in tree peony. A total of 149,842 sequences and 21,463 operational taxonomic units (OTUs) were obtained. The OTU abundance of roots was higher than leaves across other four cultivars except for ‘Kinkaku’. The community was composed of five dominant groups (Proteobacteria, Firmicutes, Bacteroidetes, Acidobacteria and Actinobacteria) in all samples. Endophytic bacteria community structures had changed in leaves and roots. At the genus level, sequences of Pseudomonas and Enterobacteriaceae were prevalent in root samples. Succinivibrio and Acinetobacter were the dominant genus in leaf samples. Otherwise, the distribution of each dominant genus among the 5 cultivars was either varied. These findings suggested that both plant genotype and tissues contribute to the shaping of the bacterial communities associated with tree peony.
