a
Length estimates from our sequence alignments.
b
Estimates based on an experimental reassessment (Schnare et al. 1986) of the original P. tetraurelia rRNA split gene structure (Seilhamer, Olsen et al. 1984). Bracketed values indicate the lengths of the rRNA segments as annotated in the mitochondrial genomes deposited in GenBank (E. minuta—GQ903130 and P. tetraurelia—NC_001324).
