Inheritance of mitochondrial DNA and plasmids in the acomycetous fungus, Epichloe typhina

Article Abstract:

The mitochondrial DNA (mtDNA) of the fungus, Epichloe typhina, progeny were studied to determine patterns of inheritance. All the progeny possessed heterogeneous plasmids while some contained plasmids from the maternal parent. The results suggest that that progeny which had nonparental mtDNA profiles developed their mitochondrial genomes through recombination. In addition, the results indicate that fertilized stroma of the fungus are initially heteroplasmic and allows parental mitochondria to fuse and recombine with their progeny.

Mitochondrial DNA length variation and heteroplasmy in populations of white sturgeon (Acipenser transmontanus)

Article Abstract:

An analysis of variation of mtDNA D-loop length in two populations of white sturgeon fish suggests heteroplasmy is supported by high recurrent mutation of multiple copy genomes and favors increased copy number. Moreover, separation to homoplasmy and selection to decreased genome size offset the pressure of mutations towards higher copy number heteroplasmy.
