摘要：
FtsZ protein plays an important role in the division of chloroplasts. With the finding and functional analysis of higher plant FtsZ proteins, people have deepened the understanding in the molecular mechanism of chloroplast division. Multiple ftsZ genes are diversified into two families in higher plants, ftsZ1 and ftsZ2 . On the basis of the research on ftsZl family, we analyzed the function of NtFtsZ2-l gene in Nicotiana tabacum . Microscopic analysis of the sense and antisense NtFtsZ2-l transgenic tobacco plants revealed that the chloroplasts were abnormal in size and also in number when compared with wild-type tobacco chloroplasts. Our investigations confirmed that the NtFtsZ2-l gene is involved in plant chloroplast division.
