Local and systemic wounding effects on PAL transcript and CT levels in aspen. A, PAL, 4CL, and COMT transcript levels in leaves and stems of aspen that were wounded, sprayed with 1 mm salicylic acid in 0.01% (v/v) Triton X-100 (SA) or with 0.01% (v/v) Triton X-100 as a control for SA treatment (Triton) on leaves 11 and 12, or were dark acclimated for 72 h. Wounding and spray treatments were repeated after 2 h and tissues harvested 24 h after the initial treatment for RNA analysis as described in Figure 2. B, Effects of a more severe 24- to 48-h wounding treatment on PAL1 and PAL2 transcript levels in injured leaves (11th and 12th) and uninjured nearby (eighth–10th) or distant (third–sixth) stem internodes.
