Mitochondrial Morphologies in drp3a and elm1 Mutants.

Mitochondria in leaf epidermal cells of wild-type plants (A) and in weak (elm1-5 [B] and drp3a-2 [C]) and severe (elm1-1 [D] and ]F] and drp3a-1 [E] and [G]) mutants transformed with Mt-GFP. Arrows indicate the constricted sites of elongated mitochondria.
