  • Title: Minireview: DNA replication in plant mitochondria.
    Author: Cupp JD, Nielsen BL.
    Journal: Mitochondrion; 2014 Nov; 19 Pt B():231-7. PubMed ID: 24681310.
    Abstract:
    Higher plant mitochondrial genomes exhibit much greater structural complexity compared to most other organisms. Unlike well-characterized metazoan mitochondrial DNA (mtDNA) replication, an understanding of the mechanism(s) and proteins involved in plant mtDNA replication remains unclear. Several plant mtDNA replication proteins, including DNA polymerases, DNA primase/helicase, and accessory proteins have been identified. Mitochondrial dynamics, genome structure, and the complexity of dual-targeted and dual-function proteins that provide at least partial redundancy suggest that plants have a unique model for maintaining and replicating mtDNA when compared to the replication mechanism utilized by most metazoan organisms.
