SAGT transcript levels in benzothiadiazole (BTH)‐treated wild‐type Nicotiana tabacum plants (Wt Nt) as determined by quantitative reverse transcription PCR. Leaf samples were harvested from plants in a greenhouse at 6–288 hr post‐treatment (hpt) with BTH (0.12 mM). Black bar: BTH‐treated, white bar: water‐treated. Levels (in arbitrary units) are for individual plants (n = 3). *Significant difference (p < .05) between the BTH‐treated and water‐treated leaves according to Student's t test. Bars indicate standard errors (±SE)
