Expression of genes encoding AabHLH TFs across A. annua tissues and stages of development. A Hierarchical clustering of expression levels in different tissues of all AabHLH genes. α, highest expression level; β, low expression level; γ, almost no expression. B Hierarchical clustering of expression levels of AabHLH genes that encode key enzymes involved in artemisinin synthesis. Asterisks denote genes in B highly expressed in trichomes, shown in C
