  • Title: Angiosperm mitochondrial genomes and mutations.
    Author: Kubo T, Newton KJ.
    Journal: Mitochondrion; 2008 Jan; 8(1):5-14. PubMed ID: 18065297.
    Abstract:
    Flowering plants harbor the largest mitochondrial genomes reported so far. At present, the nucleotide sequences of 15 mitochondrial genomes from seven angiosperm species are available, making detailed comparative analysis feasible. The gene content is variable among the species, but the most striking feature is the fluidity of intergenic regions, where species-specific sequences predominate. Additionally, angiosperm mitochondrial genomes, even within a species, show a remarkable amount of rearrangement. We also review mitochondrial mutants in angiosperms from a genomic viewpoint, and discuss how they have arisen. The involvement of nuclear genes in mitochondrial genome stability and organization is currently being revealed through the analysis of mutants.
