我们使用定量相位断层扫描与同步辐射，以阐明在其自然状态下的拟南芥种子的三维结构。细胞被清楚地区分开，它们的内部结构通过电子密度的局部变化而被揭示。我们可视化了细胞间空气空间的3D网络，该网络可能允许在萌发期间立即进行气体交换以供能量供应和/或在吸胀期间用于快速吸水和分配。
We used quantitative phase tomography with synchrotron radiation to elucidate the 3D structure of Arabidopsis seeds in their native state. The cells are clearly distinguished, and their internal structure is revealed through local variations in electron density. We visualized a 3D network of intercellular air space that might allow immediate gas exchange for energy supply during germination and/or serve for rapid water uptake and distribution during imbibition.
