The miRNA-ROS interactome: Orchestrating plant resilience to environmental fluxes.

The miRNA-ROS interactome is a conserved, multi-layered regulatory network crucial for plant stress resilience, coordinating ROS homeostasis across cellular compartments.

• Why it matters: Understanding how plants manage ROS during environmental stresses is vital for developing resilient crops, yet the complex regulatory mechanisms remain poorly characterized.
• What they did: The review synthesizes evidence from studies on miRNA regulation of ROS in different organelles, ROS influence on miRNA biogenesis, and integration with hormonal and signaling pathways, highlighting key patterns and gaps.
• The result: This framework offers insights for engineering stress-tolerant crops by targeting miRNA-ROS modules, with future research directions focusing on advanced single-cell and synthetic biology approaches.
