Comparative study reveals cryo- and methanol-fixation minimize cell deformation in delicate plant tissues, indicating optimal protocols for high-fidelity scanning electron microscopy.

Key Points

To assess how various sample preparation methods and imaging parameters affect cell deformation and structural preservation in delicate versus hard plant tissues during scanning electron microscopy.
Classified plant specimens as delicate or hard based on tissue hardness and water content.
Evaluated cell and tissue deformation across five distinct preparation protocols at tissue and single-cell resolutions.
Tested the effects of cryo-protectants, cryo-stage temperature (-30 °C), sample dimensions, leaf surface orientation (adaxial vs. abaxial), accelerating voltage, and sputter coating time on beam stability and image fidelity.
Cryo- and methanol-fixation yielded lower dimensional deformation and superior cell shape preservation in delicate plant tissues compared to standard dehydration methods.
Combining a cryo-protectant with a -30 °C cryo-stage temperature and larger sample sizes substantially increased specimen stability under the electron beam and improved image quality.
