FIGURE 8.

Growth responses of different transgenic N. attenuata lines to a B55 inoculation. Relative B55-associated growth increase of different transgenic N. attenuata lines compared to non-inoculated plants. Twenty day old plants were inoculated with B55 or mock-inoculated (late-stage inoculation). Size of the longest leaf was measured on the day of inoculation and at the end of the experiment (12 or 14 dpi). Growth increase (%) of B55-inoculated plants was calculated relative to non-inoculated plants. See Table 2 for abbreviations of genes silenced by RNAi by expression of inverted repeat (ir) constructs in the transformed lines. dpi, days post infection. n = 10.
