Microbial diversity composition of apple tree roots and resistance of apple Valsa canker with different grafting rootstock types.

ABSTRACT:

Background

The composition and diversity of root microbial community are affected by plant genotypes and soil environment, which in turn affect plant growth and development. Grafting rootstock types of the apple tree can affect phenotypes in cultivation practice, but it is not clear whether grafting rootstock types can affect the composition and diversity of root microbial community and the resistance of apple tree to apple Valsa canker.

Methods

To explore root microbial differences and the correlation, 16S rRNA and ITS genes were sequenced using Novaseq technology.

Results

The results showed that the influence of grafting rootstock types on the composition of the root fungal community was greater than that of bacteria. And the bacterial community richness was higher
