Figure 6.

Structural alignment of the 10 C/D box snoRNA genes located beyond the tDNA-Gly (GCC) genes of P. trichocarpa. Ten dicistronic tRNA-Gly (GCC)–snoRNA genes were identified in the genome of P. trichocarpa. The 10 copies of tDNA are identical and are shown under the usual cloverleaf structure (top). The 10 C/D snoRNA gene sequences shown (bottom) immediately follows nt 73 of the tDNAs. Dashes indicate the antisense element and the asterisk indicates the nucleotide targeting the methylation. Most conserved residues (in bold) are displayed in the last line.
