*2.2.2.3 Mechanism of GA3 in promoting germination*

The role of GA3 in breaking of dormancy has been documented by different workers [50, 51]. The hormone signal (GA3) activates DNA in the aleurone cells. This is followed by transcription and translation of a gene coding for α-amylase and its eventual production inside the aleurone cells. In the model for gibberellin-induced production of α-amylase, it is demonstrated that GAs produced in the scutellum diffuse to the aleurone cells, where they stimulate the secretion of α-amylase [52].
