Mitochondria increase in number by the fission of existing mitochondria. Mitochondrial fission is needed to provide mitochondria to daughter cells during cell division. In  Arabidopsis thaliana , four kinds of genes have been reported to be involved in mitochondrial fission. Two of them,  DRP3  ( dynamin-related protein3 ) and  FIS1  ( FISSION1 ), are well conserved in eukaryotes. The other two are plant-specific  ELM1  ( elongated mitochondria1 ) and  PMD  ( peroxisomal and mitochondrial division ). To better understand the commonality and diversity of mitochondrial fission factors in land plants, we examined mitochondrial fission-related genes in a liverwort,  Marchantia polymorpha . As a bryophyte,  M. polymorpha  has features distinct from those of the other land plant lineages. We found that  M. polymorpha  has single copies of homologues for  DRP3, FIS1  and  ELM1 , but does not appear to have a homologue of  PMD . Citrine-fusion proteins with MpDRP3, MpFIS1 and MpELM1 were localized to mitochondria in  M. polymorpha . Mp DRP3 - and Mp ELM1 -defective mutants grew slowly and had networked mitochondria, indicating that mitochondrial fission was blocked in the mutants, as expected. However, knockout of Mp FIS1  did not affect growth or mitochondrial morphology. These results suggest that Mp DRP3  and Mp ELM1  but neither Mp FIS1  nor  PMD  are needed for mitochondrial fission in  M. polymorpha .
