Summary The single copy psbA genes from the multicellular red alga Antithamnion spec. and the brown alga Ectocarpus siliculosus have been cloned and sequenced and monocistronic transcripts have been detected. Both genes contain an insertion of 21 bp at the 3′ end which was also found in cyanobacteria and which is absent in chloroplasts and the chlorophyll b-containing prochlorophyte Prochlorothrix hollandica. These findings are in agreement with the hypothesis of a polyphyletic origin of plastids. Plastids of red and brown algae appear to be closely related.
