Arabidopsis thaliana have been used to investigate the role of epibrassinolide (epi-BR) in cell differentiation and regeneration in vitro. The results show that calli cultured on MS medium supplemented with 0.05, 0.5 or 5.0mg/L epi-BR formed much green buds and shoots. Supplementing the culture medium with epi-BR and 0.1mg/L KT induced the greening of callus and bud formation, but KT did not induce this differentiation alone. In addition, electron microscopic examination shows that normal chloroplasts were contained in cell of green callus cultured on medium with epi-BR.
