Název v původním jazyce
The impact of cytokinins and cytokinin metabolism in in vitro shoot regeneration.
Popis výsledku v původním jazyce
The phytohormones cytokinins and auxin have been known as the principal regulators of plant development for a long time. In in vitro regeneration assays, the presence of high auxin-to-cytokinin concentration ratio in media induces root regeneration from various plant tissues. On the other hand, if the auxin-to-cytokinin ratio is low, shoots are formed. The process of in vitro shoot regeneration is accompanied by strong activation of cytokinin signalling via AHK4 receptor and induction of shoot-specific homeodomain regulator WUSCHEL specifically in the regenerating organs. Exogenous but also endogenous cytokinins influence both the initiation of newly formed organs as well as the pace of organ developmental sequence. The role of cytokinins, importance of cytokinin biosynthesis and metabolism in the control of in vitro shoot regeneration will be discussed.
