Figure 9From: SnoRNAs from the filamentous fungus Neurospora crassa: structural, functional and evolutionary insightsCoevolution between snoRNAs and their targets. A. Nucleotides of box C/D snoRNAs in the complementary region were changed in coordination with its target rRNA maintaining phylogenetical conservation of rRNA methylated sites. B. Nucleotides changed in box H/ACA snoRNAs respond to specific changes in the 18S rRNA of N. crassa . The nucleotides marked by black dot represent the 2'-O-methylation. Basepairs changed are indicated by arrows.Back to article page
