Involvement of Hormone- and ROS-Signaling Pathways in the Beneficial Action of Humic Substances on Plants Growing under Normal and Stressing Conditions

<div>Hypothetical mechanism integrating hormonal-dependent and ROS-dependent signaling pathways in the whole action of humic substances on plant root and shoot. (1) ROS-dependent pathway, (2) hormonal ROS crosstalk pathway, and (3) hormonal-dependent pathway. ???: the causal relationships between IAA-NO-ABA and ROS are yet unknown.</div>
