Table 1. Number of pRNA candidates.

The number of pRNA candidates from the assembled (contig, scaffold or finished) genomes can be reduced, according to adjacent rRNAs, A-box (part of UCE) and B-box (part of core promoter) in expected distances to pRNA candidates. We suggest a number of minimal pRNAs believed to be functional (Min pRNAs), derived from unique sequences of genome analysis, EST sequences and candidates from previous genome assemblies. Additionally, we found pRNA candidates for eleven more species: Gorilla gorilla, Nomascus leucogenys, Pongo abelii, Macaca fuscata, Macaca fascicularis, Cricetulus griseus, Cricetulus longicaudatus, Canis lupus familiaris, Pseudorca crassidens, Bubalus bubalis, and Muntiacus muntjak vaginalis. For more details see main text. f, finished; s, scaffold; c, contig; Gzise, Genomesize in Mbp; pRNA candidates, in current assembly; rRNAs, number of rRNAs within 10 000 nt downstream of pRNA candidates; i, candidates with unexpected insertion in upstream sequence; Sa, Sauropsida; Pr, Protheria; Me, Metatheria; known sequences in bold font.
