Interaction between the JA Signaling Pathway and the miR156/SPL Regulatory Module Shapes Age-Dependent Defense Investments.
(A) Decay of miR156 levels along a plant's vegetative growth results in increasing levels of miR156-targeted SPLs developmental regulators.
(B) SPL9 interaction with JAZ3 (1, close-up view on signaling within a leaf attacked by a chewing insect) prevents the degradation of this transcriptional repressor and contributes to the decay of herbivory-induced JA-Ile signaling during aging.
(C) Aged plants however maintain an elevated state of resistance to insect herbivores by predominantly relying on constitutive levels of defense compounds, glucosinolates in Arabidopsis, and possibly on their mobilization from old to young shoot tissues (2, light-to-dark blue coloring denotes predicted increases in the levels of defense compounds in younger tissues).
