Schematic overview of the re-localization of HvPDIL1-1-positive PBs during starchy endosperm development. Note the decrease of the diameter of the HvPDIL1-1 labeled PBs (green) between 6 DAP and ≥20 DAP (summarizing Figure 7, Figures S4, S8). First fusing events with the protein matrix at the periphery of starch granules (gray structures) was observed at 12 DAP and continued at ≥20 DAP. AL, aleurone; SA, subaleurone; SE, starchy endosperm; Note the indicated starch granules. The localization of HvPDIL1-1 at the plasma membrane in the SE at 12 and ≥20 DAP is indicated as the plasma membrane is green colored (summarizing Figures 7, 9B).
