Extended Data Fig. 1: Steroidal glycoalkaloid (SGA) metabolism during tomato fruit development and ripening.
From: The GORKY glycoalkaloid transporter is indispensable for preventing tomato bitterness
Cholesterol serves as a precursor for SGA biosynthesis. In tomato, cholesterol is further modified through oxidation, hydroxylation, transamination, acetylation and glycosylation to form SGAs. Dashed arrows represent multiple biosynthetic reactions whereas solid arrows represent a single step. Ac: Acetoxy; Glc: Glucose; Gal: Galactose; Xyl: Xylose.
