Abstract
IN the aleurone cells of barley seed gibberellic acid (GA) stimulates de novo synthesis of α-amylase1,2. From a study of the effect of 5-fluorouracil (FU) on the GA-evoked formation of thermolabile α-amylase molecules, Carlson3 has concluded that GA regulates a post-transcriptional control point. According to my interpretation, which differs from Carlson's conclusion, his data (Fig. 1, ref. 3) suggest that mRNAs for α-amylase are formed in the presence of GA.
