-RBOH-ROS signaling module. Elevated ROS in roots plays dual functions. First, ROS stimulates plant carbon release into the rhizosphere by increasing the permeability of root cell membranes. The released carbon flux enriches plant-beneficial bacterial genera, which in turn promotes plant growth and pollutant degradation. Second, NO acts downstream of ROS to loosen root cell walls, facilitating rhizobacterial colonization. Our findings show how plants deploy systemic signaling acquire help from rhizomicrobes, extending our understanding of plant environmental adaptability.
