To obtain information about the biosynthesis of brassinosteroids (BRs) in tomato shoots, we examined endogenous BRs by gas chromatography-mass spectrometry. We identified two C28 BRs, namely, castasterone and 6-deoxocastasterone, and a C27 BR, 28-norcastasterone. Our findings suggest that the major BRs in tomato are derived from campesterol and cholesterol.
