This study introduces a streamlined workflow for super-resolution microscopy in Arabidopsis thaliana nuclei. This method enhances visualization of chromatin organization and epigenetic regulation in plants at the nanoscale.

Area of Science:

  • Plant Biology
  • Cell Biology
  • Microscopy

Background:

  • Confocal microscopy offers limited resolution for plant nuclear chromatin architecture.
  • Super-resolution techniques like Single-Molecule Localization Microscopy (SMLM) are needed for nanoscale visualization.
  • SMLM application in plants is hindered by sample preparation challenges.

Purpose of the Study:

  • To develop a streamlined and reproducible workflow for SMLM imaging of isolated Arabidopsis thaliana nuclei.
  • To overcome technical barriers in plant sample preparation for SMLM.
  • To enable nanoscale investigation of chromatin organization and epigenetic regulation in plants.

Main Methods:

  • Developed a protocol involving seedling fixation, gentle tissue chopping, and centrifugation for nuclei enrichment.
