In order to find new brassinosteroid biosynthesis inhibitors, we investigate the effect of human 3β-hydroxysteroid dehydorgenase inhibitors including spironolactone and progesterone on cress and Arabidopsis. Among the tested compounds, only spironolactone induced photomorphorogical changes in the dark, and dwarfisim and early development of leaves in the light. These morphological changes were restored by the coapplication of brassinolide, which suggests that spironolcatone should interfer with biosynthesis of brassinosteroids.
