From: 2,4-D attenuates salinity-induced toxicity by mediating anatomical changes, antioxidant capacity and cation transporters in the roots of rice cultivars

Figure 7

A schematic model based on the present study for plant defense responses under salinity with or without 2,4-D application. Under saline stress conditions, Na+ passes through the cell membrane via nonselective cation channels (NSCC), induces membrane depolarization, which deactivate potassium (K+) inward rectifier channels (AKT) that limits plant growth by interfering with major physiological functions, disrupting ion homeostasis, diminishing nutrient uptake and produce excessive ROS and lipid peroxidation due to enhanced cellular Na+ level. 2,4-D application modulates the expression of cation transports proteins and antioxidant defense system to reduce ROS production and Na+  uptake in cell through the activation of the salt overly sensitive (SOS) signaling pathway and compartmentalization of sodium in vacuole by Na+/H+ exchangers (NHX).
