Abstract

The spatial organization of chloroplast DNA in developing and dividing wheat chloroplasts was studied in the light microscope using the fluorescent probe 4'-6-diamidino-2-phenylindole, which binds specifically to DNA.The DNA of wheat chloroplasts was localized at the periphery of the plastid, frequently in a discrete band. No relocalization of the DNA was observed during plastid replication. This peripheral location of the DNA was shown to differ from the central random location of DNA in tobacco and spinach chloroplasts.
