The response of root endophytes to different phosphorus levels in peach rootstocks with different phosphorus efficiencies

Phosphorus (P) is an important macronutrient for all lives on earth, but it is also a finite resource. Therefore, it is important to understand how to increase the P availability and uptake. The endophytes can help host plants to improve P uptake and will be significantly affected by plant cultivars and genotypes. To investigate the mechanism of root endophytes in promoting the P uptake of peach rootstocks, we analyzed the variances of the root endophytic fungal and bacterial communities of peach rootstocks with different P efficiencies under high or low level of P addition.
