Pot experiments with gradient soil moisture treatments were conducted. Amplicon sequencing was used to analyze rhizosphere microbial community dynamics and correlate community composition with disease incidence.
Key Findings:
Changes in soil water content can reshape the abundance ratio of beneficial and pathogenic bacteria in the rhizosphere of Panax notoginseng.
Elevated abundance of specific indigenous beneficial bacterial groups can significantly reduce root rot incidence.
This study proposes a novel strategy for green disease control of Panax notoginseng by field water management to regulate rhizosphere microbiome.
