| Outline of Final Research Achievements |
We investigated the cellular mechanisms of plastid replication in the ftsZ-null mutant of Arabidopsis thaliana. Fluorescence microscopy analysis of both early- and late-developing ovule integuments indicated that ftsZ amyloplasts had no activity of division during the post-mitotic cell maturation, while ftsZ proplastids could be replicated during the cell proliferation stage, overcoming the defects of the plastid division apparatus.
