The transgenic TL46 lines having the up-regulatory AGP-L1
genes expressed about 2- to 4-fold greater levels of AGPase activity
than WT, and many-fold more than the 5% activity measured for the
untransformed TL46 parent (results not shown). Consistent with
our earlier study [14], all of the transgenic lines showed enhanced
starch accumulation over the parental TL46 (Table 1).
