a Sequence homogeneity at the rRNA expression level contrasts with sequence heterogeneity at the genomic DNA level in C. revoluta. The phylogram was constructed from the genomic DNA (number) and cDNA (c + number) clones of 26S rDNA subregion (see blue double-headed arrow in Supplementary Fig. 2b). Bootstrap support of branching (>60) are indicated. (b) Phylogram constructed from cDNA (red oval) sequences from G. biloba, C. revoluta, C. circinalis, G. gnemon and Picea abies and randomly selected pseudogene (blue oval) clones from C. revoluta
