A typical cisterna originates from a dilation of the r-ER and contains a homogeneous, moderately dense material. The appearance of the cisternal content varies with the development of the cell and ranges from an electron-dense homogeneous matrix, via accumulations consisting of tightly packed longitudinally oriented rods or tubules, to vacuolar-like inclusions which eventually lose the attached ribosomes. The occurrence of DC was followed up in detail in different parts of the seedlings of Chinese cabbage (Brassica chinensis L.) 24 h, 48 h, and 72 h after germination. DC were not found in meristematic cells or cells undergoing differentiation, but appeared in more mature cells. Their number and size increased with the age and the development of the cell. DC we...Read More
