Cytokinin Profiles of AtCKX2-Overexpressing Potato Plants and the Impact of Altered Cytokinin Homeostasis on Tuberization In Vitro
Original language description
Genes encoding cytokinin oxidase/dehydrogenase (CKX) enzymes have been used lately to study cytokinin homeostasis in a variety of plant species. In this study AtCKX2-overexpressing potato plants were engineered and grown in vitro as a model system to investigate the effects of altered cytokinin levels on tuber formation and tuber size. Protein extracts from shoots and roots of transformed potato plants exhibited higher CKX activity compared to control plants. Total endogenous cytokinin levels were generally not decreased in AtCKX2 overexpressors. However, levels of bioactive cytokinins were markedly lowered, which was accompanied by increased levels of O- and N-glucosides in some transgenic lines. The AtCKX2-overexpressing plants displayed reduced shoot growth but other symptoms of the "cytokinin deficiency syndrome" were not recorded. The transgenic plants were able to produce tubers in noninducing conditions. In inducing conditions they developed larger tubers than control. Tubers we
