microbiome-disease
Plant microbiomes are communities of microorganisms that colonize plant tissues and significantly influence disease susceptibility and plant health outcomes. Understanding microbiome-disease interactions is critical for plant science because it reveals how beneficial microbial communities can enhance disease resistance and inform sustainable biological control strategies. This knowledge enables researchers to manipulate plant microbiomes to improve crop resilience and reduce dependence on chemical interventions.

Excess nitrogen in soil changes the beneficial microbes around rice roots, making the plant more susceptible to a fungal disease. Surprisingly, these altered microbial communities can persist and spread, suggesting that managing soil health is key to preventing disease in nitrogen-fertilized rice.
High nitrogen significantly alters bacterial and fungal communities in rice rhizosphere and suppresses defense genes OsPAL06 and OsPR10b
Rhizosphere microbiome transplantation from high-nitrogen infected donors to standard-nitrogen recipients reproduced nitrogen-induced susceptibility, indicating a microbiome legacy effect
Network analysis revealed reduced microbial connectivity and loss of keystone taxa under high-nitrogen and infection conditions
