Fig. 4From: Bacterial community structure and co-occurrence networks in the rhizosphere and root endosphere of the grafted appleRelative abundance of the rhizosphere and root endosphere bacteria from grafted apple at the phylum (a) and class (b) levels. Only phyla and classes with relative abundance higher than 1% were shown in at least one sample, and relative abundance less than 1% were classified as “others”. MH, M9, MB and MR represent the rhizosphere from Malus hupehensis Rehd., M9T337, Malus baccata Borkh. and Malus robusta Rehd., respectively. MHR, M9R, MBR and MRR represent the root endosphere from Malus hupehensis Rehd., M9T337, Malus baccata Borkh. and Malus robusta Rehd., respectively. Bk represents bulk soilBack to article page
