Panax ginseng is a medicinal plant belonging to the Araliaceae family. Ginseng is known as the king of oriental medicine, which has been practiced since ancient times in East Asian countries and globally in the modern era. Ginseng is used as an adaptogen, and research shows that it has several pharmacological benefits for various ailments such as cancer, inflammation, diabetes, and neurological symptoms. The pharmacological benefits of ginseng are attributed to the triterpenoid saponin ginsenosides found throughout the Panax ginseng species, which are abundant in its root and are found exclusively in P. ginseng and Panax quinquefolius. Recently, with the completion of the entire ginseng genome sequencing and the construction of the ginseng genome database, it has become possible to access information about many genes newly predicted to be involved in ginsenoside biosynthesis. This review briefly summarizes the current progress in ginseng genome analysis and genes involved in ginsenoside biosynthesis, proposing directions for functional studies of the predicted genes related to ginsenoside production and its regulation.
