Abstract
The nucleotide sequence of 23S rDNA from Zea mays chloroplasts has been determined. Alignment with 23S rDNA from E.coli reveals 71 percent homology when maize 4.5S rDNA is included as an equivalent of the 3' end of E.coli 23S rDNA. Among the conserved sequences are sites for base modification. Chloramphenicol sensitivity and ribosomal subunit interaction. A proposal for the base pairs formed between 16S and 23S rRNAs during the 30S/50S subunit interaction is presented. The alignment of maize 23S rDNA with that of E.coli reveals three small insertion sequences of 25, 65 and 78 base pairs, whereas maize 16S rDNA shows only deletions when compared with the E.coli species.Entities:
