Chloroplasts are cytoplasmic organelles and the sites of
photosynthesis in eukaryotic cells. Advances in struc-
tural biology and comparative genomics allow us to
identify individual components of the photosynthetic
apparatus precisely with respect to the subcellular lo-
cation of their genes. Here we present outline maps of
four energy-transducing thylakoid membranes. The
maps for land plants and red and green algae distinguish
protein subunits encoded in the nucleus from those
encoded in the chloroplast. We find no defining struc-
tural feature that is common to all chloroplast gene
products. Instead, conserved patterns of gene location
are consistent with photosynthetic redox chemistry
exerting gene regulatory control over its own rate-
limiting steps. Chloroplast DNA carries genes whose
expression is placed under this control.
