Autophagy alleviates the accumulation of depolarized mitochondria due to friendly mutation. (A) Confocal images of TMRE-stained mesophyll cells from WT, atg5, atg7, friendly, friendly atg5 and friendly atg7 plants expressing mitochondrial IDH-GFP. Green, IDH-GFP; magenta, TMRE. Orthogonal projections created from z-stack images are shown. Scale bars = 10 �m. The area indicated by a dashed blue box is expanded to the right of each panel. (B) Proportion of the total volume from TMRE signals in MT-GFP signals obtained from the observations described in (A) (� SE, n = 6). Different letters denote significant differences based on Tukey’s test (P < 0.05).
