From: Bark and wood tissues of American elm exhibit distinct responses to Dutch elm disease
Levels of salicylic acid (SA) and abscisic acid (ABA) in the inoculated stem tissues of ‘Valley Forge’ and ‘Princeton’. (a,b) The level of SA (ng/g FW) in the bark and core tissues, respectively, of ‘Valley Forge’ (VF) and ‘Princeton’ (P) at 0, 48, 96 and 144 hpi. (c,d) the level of ABA (ng/g FW) in the bark and core tissues, respectively, of ‘Valley Forge’ (VF) and ‘Princeton’ (P) at different time points of inoculation with the fungus. The results are the mean ± SE of three biological replicates. Values marked with an asterisk (*) are significantly higher than the control sample (P-bark at 0 hpi) and the corresponding time point in the other genotype (P < 0.05).
