Der Einfluß des Plasmotypus auf die Regulation der Aktivität der L-Phenylalanin-Ammonium-Lyase (Untersuchungen an Raimannia -Oenotheren)

摘要: The regulation of the activity L-phenylalanine ammonia-lyase (PAL) in seedlings complex heterocygotes Oenothera berteriana (with chromosome complexes B and I) odorata v their progeny was investigated. following main results were obtained: plasmotype (plasmon) has a significant effect upon amount increase PAL during illumination with continuous far-red light (Figs. 2-5). Combined genotypes v.I, B.I l.v effects higher maximal after 20 hrs than odorata. This influence plasmon is constantly inherited. characterized by order I-v-l-B; I-complex causes highest, B-complex lowest PAL-activity. Cytoplasm plastids have no apparent either on PAL-activity darkgrown or which brought about wounding (Fig. 7). Therefore it can be concluded that affects very specifically light-induced PAL-synthesis. There evidence so far for existence isoenzymes forms. Because various correlations between anthocyanin formation (Table 2), supposed takes part directing By technique simultaneous irradiation demonstrated under mediated phytochrome 6). possibility explaining forms dependent reactions basis pleiotropic mechanism discussed.
