Sesame (Sesamum indicum L.) is a significantly lucrative cash crop for millions of small-holder farmers. Its seeds are an important source of a world highly appreciated oil and two clinically essential antioxidant lignans, sesamin and sesamolin. Accordingly, many countries import annually millions of tons of sesame seeds. The demand for lignan-rich sesame seeds is increasing yearly due to the continuous discovery of several pharmacological attributes of sesamin and sesamolin. To meet the demand, the sesame breeder's primary objective is to release sesame cultivars enriched in oil and lignans. Thus, it is necessary to summarize the information related to sesamin and sesamolin contents in sesame in order to promote joint efforts of specialized research teams on this oilseed crop. In the following, we present the current knowledge on sesamin and sesamolin content in S. indicum L. with respect to the updated biosynthesis pathway, associated markers, governing loci, available variability in sesame germplasm, their in planta potential roles in sesame, and the newly discovered pharmacological abilities. In addition, we propose and discuss some required studies that might afford genomics-assisted breeding of high lignans content sesame varieties.
