Differential Assembly of Rhizosphere Microbiome and Metabolome in Rice with Contrasting Resistance to Blast Disease.

ABSTRACT: Rice blast, caused by Magnaporthe oryzae, is one of the most devastating diseases threatening global rice production. Although host resistance represents a sustainable control strategy, the underlying mechanisms mediated by the rhizosphere microbiome remain poorly understood. In this study, we selected four rice varieties with varying resistance to blast and demonstrated, through an integrated approach of 16S rRNA/ITS amplicon sequencing, untargeted metabolomics, and soil physicochemical analysis, that the rice genotype reprograms the genotype-root exudate-rhizosphere microbiome system. Results showed that the resistant variety P104 significantly decreased the soil pH while increasing the contents of total nitrogen, ammonium nitrogen, and nitrate nitrogen. On the other hand, the sus
