We distinguish the total number of candidates (Cop.) to be putatively functional (A), containing variations in sequence or structure (B), and questionable owing to variations in box motifs and secondary structure (Q). The second column depicts the state of each genome assembly: the number is calculated by the known genome size (Gregory, 2012) divided by the number of downloadable nucleotides in finished genomes (chromosomal status), scaffolds or contig.
