Transgenic plant cells are transformed into complete, mature plants through the application of tissue culture techniques.1

To regenerate a whole plant from modified cells, researchers grow the transgenic cells on specialized media supplemented with specific hormones. These growth regulators are essential for inducing organ differentiation, a process that allows the undifferentiated cell mass—often referred to as callus—to develop into roots, stems, and leaves.213

This process relies on the principle of cellular totipotency, which demonstrates that individual plant cells contain the complete genetic information necessary to produce an entire organism. Once the cells differentiate and develop into small plantlets, they can be further cultivated into mature plants. This method is a critical component of modern plant breeding, enabling the commercial introduction of various transgenic crop lines.312
