Ribosomal RNA synthesis in imbibing radish (Raphanus sativus) embryo axes : A biochemical and cytological study.

abstract：:1. The plastids of the saprophytic orchid Neottia nidus-avis contain, besides chlorophyll a, all plastidquinones and carotenoids of normal chloroplasts from higher plants. The relative concentrations of plastidquinones and carotenoids are, however, quite different from those in photosynthetically active plant tissue. ...
