    Notes: Abstract Using somatic hybrid cell lines Arabidopsis thaliana+Brassica campestris, obtained by cloning individual protoplast-fusion products as starting material, shoots and flowering plants have been regenerated. Cytological, biochemical, and morphological analyses indicate that genetic material of both species is present in the resultant plants. Shoots and plants obtained from different lines and different regeneration events differed morphologically and genetically. Most regenerants show morphological abnormalities and unusual organizational patterns. Flowering forms have so far been sterile. “Asymmetric” hybrids (i.e., hybrids bearing most genetic material of one of the parent species and only few chromosomes of the other) were more regular in morphology. The results represent the first case of intergeneric-intertribal hybridization of flowering plants.

    “Arabidobrassica”: Chromosomal recombination and morphogenesis in asymmetric intergeneric hybrid cells (1981)

    Notes: Abstract A somatic hybrid cell line, cloned from an individual protoplast-fusion product between Arabidopsis thaliana and Brassica campestris, gave rise to formation of numerous plants differing drastically in morphology. Analysis of these various regenerants, all of which originated from one and the same heterokaryon derived from the fusion of two cells, shows the unspecific elimination of chromosomes of both parental species during the callus growth phase. Whereas the parental cells have so far not been sucessfully regenerated into plants, several of their different asymmetric hybrids are capable of morphogenesis. Furthermore, chromosomal analysis indicates extensive recombination. Most of the plants are predoinantly morphologically regular. Abnormalities are mostly limited to the flowers which tend to undergo phyllody. The results demonstrate that remote somatic hybridization may have applications although true amphidiploids may not be obtainable. The transfer of small units of genetic material between distantly related species by protoplast fusion seems to be a more realistic approach than the combination of complete, highly diverse genomes.

    Notes: Ein wichtiger Mechanismus zur Entstehung und Erhaltung der Arten ist sexuelle Unverträglichkeit. Mit einer Fülle von Inkompatibilitätsmechanismen trägt die Natur dafür Sorge, daß sich Arten nur sehr bedingt miteinander vermischen können. Andererseits findet man in den Mythen und Sagen der Völker zahlreiche Fabelwesen wie Sphinx, Meerjungfrau oder geflügeltes Einhorn, in denen zwei oder mehr Arten zu einer neuen Lebensform verbunden sind, und auch der Traum von der Tomoffelpflanze war schon geträumt [13], bevor sie dann, dem literarischen Vorbild nur wenig ähnlich, geschaffen wurde [11, 12] (Abbildung 1). In der Regel handelt es sich bei diesen Fabelwesen allerdings um Chimären und nicht um Hybriden, wie sie das typische Produkt einer sexuellen Kreuzung wären. In einer Chimäre sind lediglich artverschiedene Gewebe miteinander kombiniert, ohne daß sich genetisches Material vermischt.

    Notes: Pflanzen produzieren ihre Farbenpracht, sei es die überschwengliche der Blüten und des Herbstlaubes oder nur das alltägliche Grün der Blätter, im wesentlichen durch zwei deutlich verschiedene Formen der Pigmentierung. In beiden Fällen sind Organelle, membranbegrenzte Strukturen innerhalb der Zellen, die Träger der Pigmente. Handelt es sich bei diesen Farbstoffen um fettlösliche Verbindungen, dann lagern sie in den Plastiden, sind sie wasserlöslich, findet man sie in den Vakuolen. Nur bei Algen kommen lipochrome Pigmente auch außerhalb der Plastiden vor. Es sind also entweder zahlreiche kleinere Strukturen (Plastiden) oder eine, selten mehrere, größere (Vakuole), die der Zelle, und damit oft einem ganzen Gewebe, die Farbe verleihen (Abbildung 1).
