Název v původním jazyce

Effects of cor15a-IPT gene expression on leaf senescence in transgenic Petuniaxhybrida and Dendranthemaxgrandiflorum

Popis výsledku v původním jazyce

To prevent leaf senescence of young transplants or excised shoots during storage under dark and cold conditions, the cytokinin biosynthetic gene isopentenyl transferase (ipt) was placed under the control of a cold-inducible promoter cor15a from Arabidopsis thaliana and introduced into Petuniaxhybrida ?Marco Polo Odyssey? and Dendranthemaxgrandiflorum (chrysanthemum) ?Iridon?. Transgenic cor15a-ipt petunia and chrysanthemum plants and excised leaves remained green and healthy during prolonged dark storage (4 weeks at 25 °C) after an initial exposure to a brief cold-induction period (4 °C for 72 h). However, cor15a-ipt chrysanthemum plants and excised leaves that were not exposed to a cold-induction period, senesced under the same dark storage conditions. Regardless of cold-induction treatment, leaves and plants of non-transformed plants senesced under prolonged dark storage. Analysis of ipt expression indicated a marked increase in gene expression in intact transgenic plants as well ...
