Chloroplast DNA from the fern Osmunda cinnamomea: physical organization, gene localization and comparison to angiosperm.

abstract：:By using the fluorochrome 4'-6-diamidino-2-phenylindole (DAPI) to stain DNA one can follow the pattern of events affecting plastid DNA which occur in the formation and maturation of individual zygotes of the green flagellate Chlamydomonas moewusii. This species, like C. reinhardi, expresses uniparental inheritance of ...
