Ultrastructure of tumor cell in Sedum erythrostictum leaf inoculated with Agrobacterium tumefaciens was observed. Development of lamella system in the chloroplasts of tumor cells was strikingly inferior to that of the normal cells, and many starch grains were contained in the chloroplast of infected cells. In tumor cells, nuclear membrane intruded extensively into the karyoplasm, so that the nuclei, in many cases, became hetromorphic, as has often been observed in animal cancer cells. Mitochondria were polymorphic both in the normal and the tumor cells, but the net-work structure seemed to be more condensed in mitochondria of tumor cells than those of normal cells.
