Fresh weight (FW) and dry weight (DW) of aerial vegetative parts of Arabidopsis, tobacco and wheat untransformed (WT), and transgenic plants. Data represent the average ± SEM of at least six plants.

^*Statistically significant differences between transgenic and WT parental lines, according to Student’s t-test (P < 0.001).
