Fig. 5From: Dual RNA-seq analysis provides new insights into interactions between Norway spruce and necrotrophic pathogen Heterobasidion annosum s.l.Concentrations of terpenoid compounds in phloem (a) and xylem (b) of asymptomatic and symptomatic Norway spruce trees and total concentrations of identified mono- and sesquiterpenes in the corresponding tissues (c). Error bars represent standard errors of mean values. Compounds showing statistically significant differences (p < 0.05) in their concentrations in asymptomatic and symptomatic trees are marked with an asteriskBack to article page
