Inhibition of α-glucosidase activity in extracts of transgenic barley seedlings by DNJ and G1M. Seedlings of transgenic line 21 carrying the hygromycin resistance cassette were selected as described for Figure 7. Extracts of the endosperm fraction of individual seedlings of line 21 and Golden Promise, 10 d after imbibition, were assayed for α-glucosidase activity in the absence of inhibitor (black bars) or in the presence of 50 μm, 500 μm, 1 mm, or 5 mm inhibitor (gray and white bars from left to right for each line). Values are means of measurements on six individual seedlings for each line. Error bars represent se.
