(1) and (2) denote two environmental conditions in which spikelet fertility was tested.
Transgenic plants (i.e. transformed with the RNAi vector).
Control plants that did not contain the RNAi vector.
Significant difference in spikelet fertility between transgenic and control plants (P < 0.05). In the T0 generation, plants transformed with a blank vector served as the negative control, whereas in the T1 generation, nontransgenic plants were used as the negative control.
