Figure 12. ABA inhibits PIN2 membrane delivery.

ABA (5 µM) exhibited no effect on red signal intensity in photoconverting experiments, and affected green signal intensity in both photoconverting and non-photoconverting experiments (for both p≤0.001). The differences between control and treated samples in non-photoconverting experiments were significant at every time point from 2 to 12 h (for each p≤0.001), the differences in photoconverting experiments were significant at time point 1 h (p≤0.05) and at every time point from 2 to 12 h (for all p≤0.001).
