From: Strictosidine activation in Apocynaceae: towards a "nuclear time bomb"?
Time course of strictosidine (a), catharanthine (b) and vindoline (c) contents in C. roseus leaves following MeJa and Ethephon treatment. The results for strictosidine, catharanthine and vindoline are expressed in mg/g FW of whole leaves (left y axis) and for strictosidine a calculated estimation of concentration (mM) within the epidermis is provided (right y axis). This estimation takes into account the molecular weight of strictosidine (530.56 g.mol-1), a rough estimation that 80% of the fresh weight is liquid, and a 10-fold enrichment for the epidermis fraction as compared to the whole leaves deduced from [29].
