These multilamellar bodies presented an internal compartment with fibrillar material, comparable to that present in lytic compartments. Closed plastid profiles with concentric membranes, dark, fibrillar, and disorganized contents, collectively with cytoplasmic and apoplastic multilamellar bodies, accounted for 16.3 on the atypical profiles observed. Altogether, these plastid profiles recommended the occurrence of plastid degradation and excretion out of your cell.3-D RECONSTRUCTION OF SUBCELLULAR VOLUMES OF EMBRYOGENIC MICROSPORESTable 1 | Quantitative evaluation of plastids of embryogenic microspores.

Alternatively, these plastid profiles could possibly correspond to equatorial sections of ring-shaped plastids. In other words, the atypical plastid profiles we observed might be artifactual, and title= pnas.1015994108 may possibly not engulf cytoplasm truly. In order to rule out this possibility, and to figure out the actual 3-D structure of those plastids, we performed FESEM-FIB-based 3-D reconstructions and models of large cytoplasmic areas of embryogenic microspores (Figure 4A; Supplementary Movie S1). These models confirmed the presence of three morphologically unique plastid typesFIGURE four | 3-D model of a subcellular volume of a B. napus embryogenic microspore. (A) Modeled subcellular volume. (B) Model excluding each of the cell structures however the plastids (pl). The different plastid varieties are modeled in diverse colors: traditional (light green), open profiles engulfing cytoplasm (dark green), and closed profiles (yellow) using the engulfed cytoplasm (white). (C) Standard, round-shaped plastid. (D) Disc-shaped plastid having a slight central depression (arrow). (E) Plastid beginning to engulf cytoplasm. The arrow points to a deep depression thatcreates a cytoplasmic pocket inside the plastid.
