Abstract: | Dictyosomes are found in a large number in the glandular scales of Origanum dictamnus during the early developmental stages. Later they significantly diminish when essential oil secretion starts. Phases of dictyosome duplication are frequently observed at the stage of growth of the Golgi apparatus. The process of dictyosome division starts in the middle region of the stack where a Golgi cisterna undergoes a central dilation. An analogous dilation is progressively formed in the adjacent cisternae. Finally, by membrane fusion the stack separates into two daughter stacks which organize into normal dictyosomes. |
