Core Insights - The article discusses a recent study from Northeast Agricultural University published in Cell Host & Microbe, highlighting the role of common mycorrhizal networks (CMN) in enhancing plant disease resistance through alterations in the rhizosphere microbiome assembly [5][6]. Group 1: Research Findings - The study demonstrates that CMN mediates inter-plant communication, regulating the assembly of rhizosphere microbiomes [7]. - Arbuscular mycorrhizal fungi (AMF) transfer jasmonic acid from pathogen-infected donor plants to healthy receptor plants [7]. - The transfer of jasmonic acid alters the root exudates of receptor plants, leading to changes in their rhizosphere microbiome [7]. Group 2: Mechanism of Action - Pathogen infection in donor plants triggers the transfer of jasmonic acid through CMN, activating the defense mechanisms in receptor plants [9]. - This process results in changes to the composition of root exudates, which in turn recruits beneficial microorganisms that suppress pathogen infections [9]. - The study outlines a complete pathway by which CMN enhances plant disease resistance, providing new insights for agricultural biocontrol strategies [9].
