Table 4. Conserved sequence motifs in chloroplast tRNAs from gymnosperms.

Small conserved consensus motifs were observed in the Ψ region. To be specific, except for tRNA^Ser, the Ψ-loop in tRNAs was found to contain a conserved sequence comprising U-U-C-NA-N₂ according to a multiple sequence alignment of 20 members of the tRNA gene family.

Notes.

Note that the consensus sequences are shown from 5′  to 3′. The asterisk mark (*) show the absence of conserved nucleotide consensus sequence in respective region of chloroplast tRNAs. 5′  AC-arm, 5′  Acceptor arm; ANC-arm, Anti-codon arm; ANC-loop, Anti-codon loop; Ψ-arm, Pseudouridine arm; Ψ-loop, Pseudouridine loop. The short lines under the bases in anticodon loop of tRNA^Ile are to indicate its possible modification.
