[1][2] CoRR was put forward explicitly in 1993 in a paper in the Journal of Theoretical Biology with the title "Control of gene expression by redox potential and the requirement for chloroplast and mitochondrial genomes".
[4] The term CoRR was introduced in 2003 in a paper in Philosophical Transactions of the Royal Society entitled "The function of genomes in bioenergetic organelles".
Why do mitochondria and chloroplasts require their own separate genetic systems, when other organelles that share the same cytoplasm, such as peroxisomes and lysosomes, do not?
The question is not trivial, because maintaining a separate genetic system is costly: more than 90 proteins ... must be encoded by nuclear genes specifically for this purpose.
The reason for such a costly arrangement is not clear, and the hope that the nucleotide sequences of mitochondrial and chloroplast genomes would provide the answer has proved to be unfounded.
CoRR does so by offering an answer to this question: why, in evolution, did some bacterial, endosymbiont genes move to the cell nucleus, while others did not?
