Microbial community of apple scions-rootstocks combinations

Malus.xiaojinensis Cheng et Jiang (Mx) and Malus.baccata (L.) Borkh. (Mb) were used as rootstocks and Fuji as scion to form two different grafted combinations, which Mx had better low-iron stress tolerance, while Mb was lower even it is a fairly cold resistant resource . Illumina Miseq sequencing platform was used to detect the microbial communities in bulk soil, rhizosphere and root of apple scion-rootstock combinations. The formation of microbial community whether can be affected by measuring the physical properties and the sugar content of soil and plant roots respectively.
