【 摘 要 】

Chloroplast rp123 loci potentially coding for a polypeptide homologous to the E. Coli L23 ribosomal protein are frame-shifted in spinach and several other plants, indicating that these loci are pseudogenes. In tobacco, tp123 constitutes a continuous open reading frame of 93 codons and its transcript initiates at least 66 bp upstream from the initiation codon. The N-terminal amino acid sequence of a 13 kDa protein from the 50 S subunit of tobacco chloroplast ribosomes matches that derived from the tobacco rp123 locus. This shows that rp123 is a functional gene in tobacco.
