Figure 1. Massive Mitochondrial Fusion in Three Different Contexts. (A) Freshly isolated tobacco mesophyll protoplasts contain discrete round/oval mitochondria that can be clumped into irregular aggregates. (B) Mitochondria fused into long, tubular structures 4 h after culture. (C) Interphase cell from Arabidopsis stem showing round/oval-shaped mitochondria (green). (D) Prometaphase cell from SAM with individual elongated mitochondria (green) or mitochondria fused into a massive cage-like structure (blue).
