Oligomerization of plant FtsZ1 and FtsZ2 plastid division proteins

► First proposed mechanism of Arabidopsis FtsZ assembly pathway. ► Structural characterization of the Arabidopsis FtsZ soluble pool to 2.5 nm resolution. ► First corroboration of bacterial FtsZ X-ray data in solution. ► First 3D reconstruction of a protein below 100 kDa.
