Abstract

The expression of the transgene gus was studied in all 40 callus lines, 12 regenerated T0 plants and the T1 and T2 progenies of 5 lines. The isogenic SC lines had an average expression level based on the activity of beta-glucuronidase of 158 +/- 9 units/mg protein (mean +/- SEM; n=3; variance within SC lines are expressed as standard error of the mean SEM) indicating a significantly higher level of expression, as compared to MC lines that had a much lower expression level 44 +/- 8 units/mg protein (mean +/- SEM; n=3) and the imprecise lines that had 22 +/- 8 units/mg protein (mean +/- SEM; n=3). Transgene expression in the callus cells of precise single copy lines varied by ∼3 fold, whereas that in multi-copy lines varied by ∼30 fold. Furthermore, precise single copy lines, on an average, contained ∼3.5 fold higher expression than multi-copy lines. Transgene expression in the plants of precise single-copy lines was highly variable, which was found to be due to the loss of the integration because of CRE-mediated reversion in the locus.
