Abstract
Modulation of active cytokinin levels in planta involves many metabolic conversions like biosynthesis, degradation, interconversion, and both reversible and irreversible conjugation. The subcellular compartmentation of this network determines the final level of the active hormone inside the cell. The over-expression in transgenic tobacco of Zm-p60.1, a maize beta-glucosidase capable of releasing active cytoninin from O-glucoside conjugates, leads to a disruption of zeatin metabolism and a hypersensitivity to exogenous zeatin.
Abstract (in Czech)
Modulace hladiny aktivních cytokininů zahrnuje mnoho metabolických přeměn, jako je biosyntéza, degradace, přeměny a reversibilní i nereversibilní konjugace. Subcelulární kompartmentace těchto reakcí určuje výslednou hladinu aktivního hormonu v buňce. Nadprodukce Zm-p60.1, kukuřičné beta-glukosidasy schopné uvolnit aktivní cytoninin z O-glukosid konjugátů, v transgenním tabáku vede k porušení metabolismu zeatinu a hypersensitivitě vůči exogenně přidanému zeatinu.
