主　　题：Apple Microbial community Rootstock genotype Ecology niche 

摘      要：Microorganisms play an important role in plant growth,health and ecological *** is necessary to explore the microbial community because of the significant ecological and economic value of apples(Malus x domestica).However,the related bacterial communities in different ecological habitats are not clear in the unique scion/rootstock combinations of *** this study,the Illumina Miseq platform was used to analyze the bacterial communities in different niches(bulk soil,rhizosphere soil and roots)of two scion/rootstock combinations[Fuji/Malus xiaojinensis Cheng et Jiang(Mx)and Fuji/Malus baccata(L.)Borkh.(Mb)].The relationship between the microbial community,soil properties,and plant characters was *** results showed that the diversity of the bacterial community decreased from bulk soil to rhizosphere soil and then to *** addition,at the phylum level,Proteobacteria,Actinobacteria and Acitinobacteria were dominant and had notable divergence in different ecological *** niches had remarkable effects on the diversity and composition of the bacterial community according to *** rootstock genotype had an effect on the bacterial composition but no effect on the ***,soil organic matter(SOM),alkaline hydrolyzable nitrogen(AN)were the main factor affecting the structure of bacterial community in rhizosphere soil,as shown by Pearson *** taxa in the roots were affected by starch,fructose,sucrose and *** study showed the microbial community structure in different ecological niches of different scion/rootstock combinations and provided some evidence for understanding the microbial-plant interaction of apple rootstocks.
