Chemical analyses of SA and JA hormone levels.

<p>A) SA levels in WT (gray bars) and PAP green (black bars) plants before and after 8 h, 48 h, 5 days and 18 days of <i>B. tabaci</i> infestation. B) JA levels in WT (gray bars) and PAP green (black bars) plants during the same infestation periods. Values are means of ng SA or JA per g fresh weight (FW) ± standard error. Asterisks indicate significant differences (<i>P</i>≤0.05) between WT and PAP green plants in each time point. The hat symbol indicates nearly significant differences (<i>P</i> = 0.07).
