Chloroplast morphology and FtsZ2–YFP localization is affected by a point mutation in ADT2. (A) Chloroplasts in wild-type A. thaliana Col-0. (B) Chloroplasts in adt2-1D A. thaliana mutants. (C) Close-ups of chloroplasts observed in adt2-1D to show the heterogeneity in shape and size. (D) Transiently expressed FtsZ–YFP in wild-type Col-0 localizes as expected to a single ring at the equatorial plane. (E) In contrast, FtsZ2–YFP localizes as long spiralling filaments within adt2-1D chloroplasts. (D, E) Images of chlorophyll fluorescence (left) and FtsZ2–YFP (middle) are shown separately and merged (right).
