“…In Euglena gracilis (242) and in both C. reinhardtii and C. moewusii (43,277), the ribosomal protein gene cluster also contains rplS, which does not appear to be present in the chloroplast genomes of land plants. However, the Euglena operon lacks rpsll, which is now in a separate operon with rps4 (242,597). The Chlamydomonas operons lack rps3, but open reading frames with homology to rps3 are found elsewhere in the chloroplast genome (see below).…”

“…5) but is separated from this operon by exon 1 of the psaA gene and two tRNA genes, tmM and trnG (277). In Euglena gracilis, rps4 is transcribed together with rpsll (242,597). In the alga Cryptomonas 'F, rps4 is close to rbcL on the same strand and is flanked by tRNAArg on the opposite strand (127), whereas in Cyanophora paradoxa, tRNA et and tRNAG'Y are adjacent to rps4 but on the opposite strand (32,598).…”

ORIGIN OF CHLOROPLASTS Chloroplasts and mitochondria contain protein synthesizingsystems more similar to those of bacteria than to those of the eukaryotic cytoplasm, consistent with the hypothesis that these organelles had xenogenous (endosymbiotic) rather than autogenous (intracellular differentiation) origins (see. references 5, 205, 220-223, 274, 633, and 694 for discussions). Phylogenies based mostly on rRNA sequences indicate that the cyanobacteria are ancestral to chloroplasts while the members of the alpha subdivision of the purple sulfur bacteria are the likely progenitors of mitochondria (221, 222). Whether the, chlorophyte algae and land plants on the one hand, and the rhodophyte, chromophyte, and euglenoid algae on the other represent more than one endosymbiotic event remains unresolved (130, 403, 434).
