Cytokinins – regulators of de novo shoot organogenesis

Plants, unlike animals, possess a unique developmental plasticity, that allows them to adapt changing environmental conditions. A fundamental aspect of this plasticity is their ability undergo postembryonic de novo organogenesis. This requires the presence regulators trigger and mediate specific spatiotemporal changes in programs. The phytohormone cytokinin has been known as principal regulator plant development for more than six decades. In shoot organogenesis vitro regeneration, cytokinins are prime candidates signal determines identity. Both processes apical meristem accompanied by gene expression, cell fate reprogramming, switching-on shoot-specific homeodomain regulator, WUSCHEL. Current understanding about role regeneration will be discussed.
