Abstract The phylogenetic position of the golden-yellow alga Ochromonas danica chrysoplast was investigated by comparison of the 16S rRNA catalogue and two long 16S rRNA stretches (804 and 454 bases) with catalogues from eubacteria and chloroplasts and with homologoes 16S rRNA regions from Escherichia coli, Bacillus subtilis, Heliobacterium chlorum, Anacystis nidulans and chloroplasts from Zea mays, Nicotiana tabacum, Euglena gracilis and Chlamydomonas reinhardii, respectively. Both approaches indicate a closer relationship of the chrysoplast to chloroplasts and cyanobacteria than to the brownish photoheterotrophic Heliobacterium chlorum for which a common ancestry has recently been hypothesized.
