Supplementary Fig. 1. Fresh weight (A, B) growth curves of lovage hairy roots grown in darkness (A, C) and under 16h light/8h dark photoperiod conditions (B, D) in SH (), SHa ( ), SHb (), SHc (), SHd (), SHe (), SHf () and SHg () liquid media. NH4+:NO3- ratios SH 10:90; SHa 0:100; SHb 100:0; SHc 50:50; SHd 25:75; SHe 90:10; SHf 10:0 and SHg 0:90.
Supplementary Fig. 2. Examples of the components present in the Levisticum officinale hairy root volatiles and their relation to the main biosynthetic pathways.
Supplementary Fig. 3. Dendrogram obtained by cluster analysis of the percentage composition of volatiles from L. officinale hairy roots, maintained in media with different ammonium:nitrate ratios (SH 10:90; SHa 0:100; SHb 100:0; SHc 50:50; SHd 25:75; SHe 90:10; SHf 10:0 and SHg 0:90), in darkness (D) and under 16h light/8h dark photoperiod (P) conditions, based on correlation and using the unweighted pair-group method with arithmetic average (UPGMA). The measure of the goodness of fit between the cophenetic value obtained from the dendrogram and the correlation matrix showed a good fit with a cophenetic correlation value of 0.82.

Supplementary Table 1. Percentage composition of the minor components of the mixtures of volatiles isolated from lovage hairy root cultures, i.e., those that appeared in relative amounts <5% at least once in the volatiles of cultures grown in media with different ammonium:nitrate ratios, maintained in darkness or photoperiod conditions. NH4+:NO3- ratios SH 10:90; SHa 0:100; SHb 100:0; SHc 50:50; SHd 25:75; SHe 90:10; SHf 10:0 and SHg 0:90.
