[The expression level of FtsZ protein during the dedifferentiation and redifferentiation of explants of Nicotiana tobacum].
The explants cells of Nicotiana Tobacum undergo the process of dedifferentiation and redifferentiation under the treatment of phytohormone with different contentrations. By monitoring the change of plastids and the expression of FtsZ protein, which functions in the progress of chloroplast division, we show that chloroplasts turn into amyloid and hypostasis when explants dedifferent and at the same time the expression of FtsZ proteins decreases. When explants redifferent and bud, hypostasis turn back into the chloroplast and the expression of FtsZ protein restores. The concurrence of fluctuant expression of FtsZ protein and the progress of bud differentiation and formation of chloroplast play essential roles in the growth of green plant.
