Rewiring Steroidal Metabolic Pathways for Diosgenin Production in Solanum nigrum

open access: yesPlant Biotechnology Journal, Volume 24, Issue 5, Page 3032-3047, May 2026.
ABSTRACT Diosgenin is a key starting material for the synthesis of steroidal drugs, such as corticosteroids and sex hormones. While the primary commercial source of diosgenin is the tubers of Dioscorea spp., identifying alternative plant hosts capable of diosgenin biosynthesis could enhance its production.
