“…Bacterial endophytes, in particular, contribute to host tolerance or resistance to biotic and abiotic stresses and have been explored for their use as biocontrol agents ( Friesen et al, 2011 ; Mercado-Blanco and Lugtenberg, 2014 ; Rosenblueth and Martínez-Romero, 2006 ). Understanding plant-endophytic microbe interactions is crucial for developing sustainable agricultural practices with reduced reliance on pesticides and chemical fertilizers ( Scholthof, 2001 ).…”

The rice blast disease, caused by the fungal pathogen, Magnaporthe oryzae (syn. Pyricularia oryzae), poses a significant threat to the global rice production. Understanding how this disease impacts the plant’s microbial communities is crucial for gaining insights into hostpathogen interactions. In this study, we investigated the changes in communities of bacterial and fungal endophytes inhabiting different compartments in healthy and diseased plants. We found that both alpha and beta diversities of endophytic communities do not change significantly by the pathogen infection. Rather, the type of plant compartment appeared to be the main driver of endophytic community structures. Although the overall structure seemed to be consistent between healthy and diseased plants, our analysis of differentially abundant taxa revealed the specific bacterial and fungal operational taxonomic units that exhibited enrichment in the root and leaf compartments of infected plants. These findings suggest that endophyte communities are robust to the changes at the early stage of pathogen infection, and that some of endophytes enriched in infected plants might have roles in the defense against the pathogen.
