From: The mitochondrial and plastid genomes of Volvox carteri: bloated molecules rich in repetitive DNA
Fraction of noncoding DNA plotted against genome size for the available organelle genomes from streptophytes, chlorophytes, and other plastid-harbouring taxa. The data points corresponding to the mtDNA and the ptDNA of V. carteri and those of its close relative C. reinhardtii are labelled and marked with arrows on the appropriate graph. The noncoding-DNA contents and genome sizes from which these two graphs were plotted are listed in Supplementary Table S1 [see Additional file 1]. Values of 30 kb and 420 kb, respectively, were chosen, based on our sequence data, as minimum-size-estimates of the mitochondrial and plastid genomes.
