Abstract

The higher plant chondriome is highly dynamic both in terms of the morphology and velocity of individual mitochondria within any given cell. Plant mitochondrial dynamics is a relatively new area of research, but one that has developed considerably over the early years of this century due to the generation of mitochondrially targeted fluorescent protein constructs and stably transformed lines. Several putative members of the plant mitochondrial division apparatus have been identified, but no genes have been identified as being involved in mitochondrial fusion. Despite the highly dynamic nature of plant mitochondria there is little specific scientific evidence linking mitochondrial dynamics to organelle and cell function. Two exceptions to this are the changes in mitochondrial dynamics that are early events during the induction of cell death programmes, and the extensive mitochondrial fusion that occurs before cytokinesis, although in both cases the role(s) of these events are a matter for conjecture.
