Abstract: | Summary The peripheral reticulum (PR) inCyphomandra betacea chloroplasts originates as vesicles budding from the inner membrane of the chloroplast envelope which elongate to form tubules then aggregate or branch to form discrete PR units. Individual PR units of many coiled tubules may be connected with other units by narrow tubules. Serial sectioning revealed the discrete units to be approximately 650–1,000 nm wide, 400–500 nm high and 500–600 nm deep and to possess a compact morphology. TheCyphomandra PR structure is compared to the morphologies of chloroplast reticula reported for other plant species. A scheme to group PR from different species into 3 distinct morphological categories is outlined and discussed. |
