Plant protoplasts culture plays an important role in biology technology. Plant protoplast is the exposed cell wrapped by plasma membrane whose cell wall is removed. Because of losing of protection from the cell wall, protoplasts are weak. Callus induction from Arabidopsis protoplasts is effected by many factors, but this work has not been systematically and accurately studied. In this study, we induced callus from the Arabidopsis protoplasts and confirm the conditions of the callus induction from Ar...
