cryo-et
Cryo-electron tomography (cryo-ET) is a high-resolution imaging technique that preserves and visualizes frozen biological samples in three dimensions at near-native resolution. In plant science, cryo-ET is particularly valuable for revealing the fine details of plant cell architecture—including cell walls, organelles, and cell-to-cell connections—without the distortions introduced by conventional sample preparation methods. This capability enables researchers to examine plant cellular structures and macromolecular complexes at the nanometer scale, advancing understanding of plant physiology and development.
