Superresolution live imaging of plant cells using structured illumination microscopy

Area of Science:

• Plant Cell Biology
• Microscopy Techniques
• Cytoskeleton Dynamics

Background:

• Superresolution microscopy is established for non-plant organisms.
• Time-lapse structured illumination microscopy (SIM) is underdeveloped for plant cells.
• Cortical microtubules are crucial for plant cell structure and division.

Purpose of the Study:

• To develop and validate a user-friendly protocol for time-lapse SIM in plant cells.
• To enable detailed observation of cortical microtubule dynamics.
• To provide a widely applicable method for plant cell imaging.

Main Methods:

• Utilized a commercial SIM platform.
• Developed a protocol including microscope calibration, channel alignment, and PSF generation.
• Established methods for sample preparation, image acquisition, reconstruction, and validation.

Main Results:

• Successfully implemented time-lapse SIM for plant cell imaging.
• The protocol is applicable to various plant cell types.
• The method allows for detailed visualization of cortical microtubules.

Conclusions:

• A validated, user-friendly protocol for time-lapse SIM in plant cells is now available.
• This method facilitates the study of dynamic processes like cortical microtubule organization.
• The protocol can be completed within two to three working days.
