Presented data compile information from [22] for Plasmodium falciparum, [190] for yeast (completed with statistics made available via the Comprehensive Yeast Genome Database website, [191]), the Arabidopsis genome initiative [192] for Arabidopsis, and the International Human Genome Sequencing Consortium [193] and [194] for Human (completed with statistics made available via Ensembl, [195]). These statistics at the complete genome release date have been continuously updated since then.
