Figure 7. Modulation of plant development and acclimation to salinity are interconnected responses influenced by miR393 regulation node.

Figure 7

These two processes are strongly regulated by reciprocal interaction between ROS and auxin signaling pathway. NaCl-mediated stress would conduct to miR393 induction that targets TIR1-AFB2 auxin receptors leading to stabilization of Aux/IAA repressors and down- regulation of auxin signaling pathway. In turn, auxin modulation influences on ROS-associated metabolism. Salt exposition leading to SIMR would be under negative regulation of the auxin signaling pathway. Depending on time and intensity of salt stress, early ROS-auxin crosstalk may exert impact on SIMR and tolerance to salinity. Others hormones and/or miRNAs may also regulate auxin-dependent pathway and physiological responses during acclimation to salinity.
