We also measured, the accumulation level of the GLP-1 analogue in elite genetically
modified rice seeds produced by a conventional binary vector
system (Fig. 2, lane 8 and Fig. 3, lane 8). This elite line was selected
from _50 genetically modified rice lines regenerated
from hygromycin-resistant calli. Independent grains from this
elite line accumulated the GLP-1 analogue in amounts ranging
from _10 to 20 lg/20 mg seed (Fig. 3, lane 8). These results
indicate that the Hm/MAT-vector system tends to increase
the accumulation level of the chimeric GLP-1 analogue/globulin
protein.
