A conserved, Mg²+-dependent exonuclease degrades organelle DNA during Arabidopsis pollen development.

The Plant cell - 1 Apr 2011

Abstract excerpt

In plant cells, mitochondria and plastids contain their own genomes derived from the ancestral bacteria endosymbiont. Despite their limited genetic capacity, these multicopy organelle genomes account for a substantial fraction of total cellular DNA, raising the question of whether organelle DNA quantity is controlled spatially or temporally. In this study, we genetically dissected the organelle DNA decrease in...
