Electron Microscope Tomography and Single-particle Reconstruction

Electron Microscope Tomography and Single-particle Reconstruction

Transmission electron microscopy (TEM) can be used to determine the 3D structure of biological samples with the help of techniques such as electron microscope tomography and single-particle reconstruction. While single-particle reconstruction can examine macromolecules and macromolecular complexes in vitro conditions only, tomography permits the study of cell components or small cells in vivo.
Electron Tomography
Electron tomography can be performed either in TEM or STEM (scanning transmission...

$X-ray Diffraction of Biological Samples$ 01:10

X-ray Diffraction of Biological Samples

X-ray diffraction or XRD is an analytical tool that utilizes X-rays to study ordered structures such as crystalline organic and inorganic samples, polycrystalline materials, proteins, carbohydrates, and drugs.
According to Bragg's law, when X-rays strike the sample positioned on a stage, the rays are scattered by the electron clouds around the sample atoms. The X-ray diffraction or scattering is caused by constructive interference of the X-ray waves that reflect off the internal...

Background:

Palynology relies on detailed pollen morphology for taxonomy.
Traditional methods often require sample preparation that can alter structures.
Advancements in X-ray microscopy offer new possibilities for non-destructive imaging.

Purpose of the Study:

To apply high-resolution laboratory-based hard X-ray microscopy to unstained pollen grains.
To visualize and quantify the 3D surface and internal structures of pollen.
To assess the utility of this technique for palynological studies.

Main Methods:

Utilized a laboratory-based X-ray microscope with Zernike phase contrast.
Acquired statistically relevant, information-rich images of pine pollen.
Performed tomographic reconstruction to obtain 3D data.
Calculated specific volumes of exine, intine, and cellular structures.

Main Results:

Successfully visualized surface and internal structures (exine, intine, cellular) of pine pollen.
Achieved clear visualization of unstained whole pollen grains.
Quantified the volumes of different pollen structures from tomographic data.

Conclusions:

Laboratory-based hard X-ray microscopy is effective for high-resolution 3D imaging of pollen.
This technique provides essential morphological and structural data for palynology.
The findings have implications for forestry, agriculture, horticulture, plant breeding, and biodiversity.
