摘要: Increased ferritin quasicrystalline inclusions were obtained in Xanthium pensylvanicum leaves by a method of “iron treatment” applied to the cocklebur plants. Clusters ca. 0.5 μ diameter inherent electron dense particles consisting iron cores (50–60 A diameter) observed microscopically plastids and mature chloroplasts. In addition commonly occurring plastidal ferritin, some cytoplasmic (lipoidal) globules have been shown contain scattered particles. cases chloroplast bearing this inclusion demonstrates changes external shape alterations from normal contour. Additional aspects aggregate its function are discussed.
