Characterization of transgenic lines expressing two invertase inhibitors under two root‐specific promoters. The phenotype of the selected Arabidopsis transgenic plants was examined after 7 weeks of growth in long‐day conditions. (A) Shoot and root fresh weights were quantified and the shoot to root ratio was determined for at least eight plants of each independent line. Values are referred to those of control plants (WT), considered as 100%. (B) Total seed weight per plant was determined in each individual plant after siliques were dried and the seeds collected. The normal distribution of seed weight was calculated for each plant and the results are plotted for all transgenic lines. The experiment was repeated three times.
