Summary rps10, encoding the plastid ribosomal protein S10, is a nuclear gene in higher plants and green algae, and is missing from the large ribosomal protein gene cluster of chlorophyll b-type plastids that contains components of the prokaryotic S10, spc and alpha operons. The cyanelle genome of Cyanophora paradoxa is shown to harbor rps10 as another specific feature of its organization. However, this novel plastid gene is not contiguous with the genes of the “S10” operon, but is adjacent to, and cotranscribed with, the str operon, a trait also found in archaebacteria.
