In Vicia faba, the plastids of the suspensor have a structure that is unique for this tissue. Their development was followed from 4 to 15 days after pollination (dap), when the suspensor has started to degenerate. The appearence of the plastids changes from small and rounded to large and more or less amoeboid. A distinct peripheral reticulum and ribosomes are present throughout plastid development. At 11 dap, most plastids have formed one or more prolamellar bodies. After zinc iodide-osmium tetroxide staining, the plastids also show strongly electron-scattering bundles of membrane tubules, sometimes with cross-linking between individual thylakoids. At 13-14 dap, the thylakoid system includes large electron-transparent spaces that are traversed by undulating membranes. Such a structure is characteristic of chromoplasts containing carotenoid crystals. In the light microscope, crystals are seen as bright red inclusions in the plastids.
