(2R,3S)-Brassinazole
Brassinazole (0.5, 1, 5 μM) causes markedly deformed seedlings, whose morphology is similar to that of BR-deficient mutants. Brassinazole causes cress dwarfism, altering leaf morphology such as the typical downward curl and dark green appearance of Arabidopsis BR-deficient mutants. However, administration of 10 nM BR reversed dwarfism.
