Exogenously applied 3-dehydro-24-epi-teasterone is transformed by cell suspension cultures of Lycopersicon esculentum to give the metabolites 24-epi-teasterone and 24-epi-typhasterol in about equal but low quantities. The major portion of 24-epi-teasterone was found as carbohydrate conjugates while 24-epi-typhasterol occurred in free form, indicating significant influence of glycosidation on the equilibrium between both compounds. The importance of these conjugation processes for the regulation of the brassinosteroid biosynthesis is discussed.In tomato cell cultures, 3-dehydro-24-epi-teasterone is transformed both to 24-epi-teasterone and 24-epi-typhasterol. The ratio between both epimers is regulated by glycosidation in 3β-position
