Discovery of mitochondrial endonucleases

Prokaryotic endosymbiont-derived organelles (i.e. mitochondria and chloroplasts), contain their own genomes and the copy number of organelle genomes per cell is high; indeed, a previous study calculated that in Arabidopsis thaliana, each cell has 1000 to 1700 copies of the chloroplast genome (Zoschke et al., 2007). Moreover, the copy number changes drastically under specific conditions; […]
