Plastids, amylase

The 8-h lag period after GA addition is followed by a 16-(or more) h period of rapid a-amylase synthesis (Fig. 7.1 A). More ultrastructural changes are said to occur in the aleurone cells during this time [66]. These include further proliferation of the RER, distention of the RER cisternae, continued reduction in the size of the aleurone grains, decreases in the number of oil bodies, an increase in the number of plastids, and loss of the phytin globoid.
