Effects of antimycin A on plastid morphology in Arabidopsis thaliana roots. Leucoplasts in the mature cortex of main roots (A and B) and amyloplasts in the columella cells at the root tip (C and D) from 1-week-old seedlings were visualized by plastid-targeted cyan fluorescence protein (CFP). CFP images are shown for the mock-treated sample (A and C) and for the samples treated for 2 hours with 50 µm antimycin A (B and D). Bar = 10 µm.
