摘要： There is a complex symbiotic relationship between plants and rhizosphere bacteria: the rhizosphere exudates of plants can affect the rhizosphere bacterial communities. However, the effects of the genotypes of different Quercus species on rhizosphere bacteria remain unclear. In the present study, we explored the diversity and abundance of rhizospheric bacterial communities in five Quercus species Quercus aliena (AS), Quercus dentate (DS) (Wagner et al., 2016), Quercus mongolica (MS), Quercus variabilis (VS), and Quercus wutaishanica (WS). The rhizosphere bacterial alpha diversity indices were significantly different, with AS showing the highest and VS the lowest diversity. In addition, Proteobacteria (28.7%-38.9%) and Firmicutes (11.2%-23.9%) were the two dominant phyla with apparent changes in relative abundance. Moreover, higher levels of metabolism were observed in AS (17.23%), followed by DS (16.61%), and the major metabolic function of bacteria in AS and DS was higher than that in MS, WS, and VS. The genetic relationship between Q. aliena and Q. dentata was relatively close, and the relative abundance of their rhizosphere bacteria (such as Proteobacteria and Bacteroidota) was similar. Conversely, the relative abundance of rhizosphere bacteria (such as Bacteroidota and Acidobacteria) varied greatly owing to the genetic relationship of Q. variabilis compared to the other relatively distant species. Therefore, our results suggest that the diversity and relative abundance of rhizosphere bacteria correlate with genetic relationships among different Quercus species.
