261Oben links: Der berühmte homöotische deficiens/globosa-(loss-of-function-)Phänotyp ist auch bei Physalis aufgetreten (rekurrente Variation):"It was expected that losses in the homeotic B class genes, Deficiens and Globosa – whose homeotic phenotype was, as far as is known, firstdetected in Antirrhinum majus in 1917 (Baur 1924, 1930; Stubbe 1966), with Deficiens being the first homeotic plant gene to be cloned andcharacterized (Sommer et al. 1990; Schwarz-Sommer et al. 1992; shortly followed by Globosa, Tröbner et al. 1992) – would display anextraordinarily uncommon phenotype in Physalis. In the deficiens and globosa mutants of A. majus (and in other flowering plants [likeMisopates: see Lönnig et al. 2007: http://www.weloennig.de/Dollo-1a.pdf] with null mutations in the homologous class B gene(s)), the petalwhorl is transformed into a second whorl of sepals and stamens to carpels. Thus, I assumed that such a mutant in Physalis developing two whorlsof sepals in anthesis would also later develop a lantern within a lantern. The prediction was, in fact, fulfilled as expected (see Fig. 12). Note that,in contrast to the WT, in this mutant too, lantern formation – even double lantern formation – again occurred regularly without fertilization.”(Vgl.
