  Fig. S1. Chloroplasts in primary leaf petioles of 14-day light-grown arc11 seedlings. (A-E) Elongated and expanded chloroplasts with or without constriction sites observed by light microscopy. (B) Asymmetrically dividing chloroplasts. (C,D) The most severe phenotype of arc11 chloroplasts showing six constriction sites along the length of chloroplasts. (E) Heterogeneity of chloroplasts with respect to size and division stage in a cell. Black arrowheads indicate constriction sites in dividing chloroplasts. A white arrowhead in C indicates production of a mini-chloroplast which looks like a budding phenotype. Arrows in B and E indicate plastid envelope membrane-derived tubular structures, called stromules, which could connect two chloroplasts. Bar, 10 mm.
