Abstract

There are almost no data describing chloroplast genome organization in chromophytic (chlorophyll a/c) plants. In this study chloroplast ribosomal operon placement and gene organization has been determined for the golden-brown alga Olisthodiscus luteus. Ribosomal RNA genes are located on the chloroplast DNA inverted repeat structure. Nucleotide sequence analysis, demonstrated that in contrast to the larger spacer regions in land plants, the 16S-23S rDNA spacer of O. luteus is only 265 bp in length. This spacer contains tRNA(Ile) and tRNA(Ala) genes which lack introns and are separated by only 3 bp. The sequences of the tRNA genes and 16S and 23S rDNA termini flanking the spacer were examined to determine homology between O. luteus, chlorophytic plant chloroplast DNA, and prokaryotes.
