Immunoelectron micrographs of B. natans plastids showing localization of BnFtsZD proteins. Images present immunogold localization of BnFtsZD-1 (a to d) and BnFtsZD-2 (e to i). Conjugated gold particles (10 nm) are highlighted with red arrowheads. (a) Longitudinal section of plastid stroma (PS) with a projecting pyrenoid (Py). (b, g) Transverse sections of pyrenoids. (c, h) Mid-sections of plastid stroma with a nucleomorph (Nm). (d, i) Transverse sections at the bottom of plastid stroma. (e) Serial longitudinal sections of a plastid. (f) Longitudinal section of a pyrenoid. The scale bars represent 1 μm. (j) Schematic illustration of BnFtsZD localization in the plastid; red and blue circles correspond to BnFtsZD-1 and BnFtsZD-2, respectively
