【 摘 要 】
A computer-aided search for potential ribosome recognition sequences of mRNAs from tobacco chloroplasts shows that more than 90% of mRNA species contain sequences upstream of the respective initiator codons, which allow base pairing with 3′-terminal sequences of small subunit rRNA. This complementarity in several cases involves 16 S rRNA sequences between the canonical CCUCC sequence and the 3′-terminal stem/loop structure. The distances between potential ribosome recognition sequences and initiator codons can be up to 25 nucleotides which is much greater when compared to the spacing of 7±2 nucleotides observed for the classical Shine-Dalgarno sequences in bacterial mRNAs.
