Abstract

In the chlorotic leaves of the Oenothera hybrid Oe. (lamarckiana × hookeri) velans·hhookeri with lamarckiana plastids the differentiation of the chloroplasts is disordered in different ways because of a disharmony between genom and plastom. Some of the plastids possess numerous vesicles and plastoglobuli but only a few isolated grana instead of the normal thylakoid system. Furthermore, the plastids contain lattice-like structures consisting of fibrils with a thickness of approximately 5 to 11 nm. These networks are connected with thylakoids, vesicles or plastoglobuli. They are interpreted as fragments of prolamellar bodies. Sometimes prolamellar bodies are distinctly recognizable in the chloroplasts even though the thylakoid system is rather well differentiated.
