Role of inhibitors in the induction of differentiation in callus cultures of Brassica, Datura and Nicotiana.
The effect of various inhibitors on differentiation (shoot morphogenesis) in callus cultures of Brassica, Datura and Nicotiana has been investigated. Hormone medium without any inhibitor (control), resulted in 6% shoot formation. Addition of inhibitors such as actinomycin D, cordycepin, abscisic acid, trigonelline and theophylline greatly enhanced shoot formation. The results suggest that inhibitors play a regulatory role in the control of differentiation.
