Fig. 5 in 21-Hydroxypregnane 21-O-malonylation, a crucial step in cardenolide biosynthesis, can be achieved by substrate-promiscuous BAHD-type phenolic glucoside malonyltransferases from Arabidopsis thaliana and homolog proteins from Digitalis lanata

Fig. 5. Expression of Dlmat1, Dlmat2, Dlmat3, and Dlmat4 in different plant tissues measured by real-time quantitative PCR (qPCR). Expression rates are standardized to the values of the actin transcript in each tissue and were displayed in relation to the expression in young leaves (set to equal 1) for each Dlmat gene.
