Distribution of the mitochondrial linear plasmids in eukaryotes. A Distribution of the mitochondrial linear plasmids in major eukaryote groups. Numbers indicate the numbers of species used. Closed and open green circles indicate the presence and absence of the mitochondrial linear plasmids in the corresponding eukaryote groups, respectively. B Distribution of mitochondrial linear plasmids in plants. Numbers near plants indicate the numbers of species used. Closed and open orange circles indicate the presence and absence of the mitochondrial linear plasmids in the corresponding plant groups, respectively. Numbers in the circles represent the number of species with mitochondrial linear plasmids. C Distribution of mitochondrial linear plasmids in fungi. Numbers near fungi indicate the numbers of species used. Closed and open blue circles indicate the presence and absence of the mitochondrial linear plasmids in the corresponding fungal groups, respectively. Numbers in the circles represent the number of species with mitochondrial linear plasmids
