A long term time lapse microscopy technique for Arabidopsis roots

Area of Science:

• Plant biology
• Cell biology
• Microscopy

Background:

• Time lapse microscopy is crucial for plant cell and developmental biology.
• Light sheet microscopy offers reduced phototoxicity and increased signal intensity for imaging.
• Existing light sheet systems often lack optimization for unique plant sample requirements.

Purpose of the Study:

• To adapt a novel light sheet microscopy system for imaging regenerating Arabidopsis roots.
• To develop new protocols for sample preparation and automated root tip tracking.
• To enhance researcher accessibility to long-term time-lapse imaging in plant biology.

Main Methods:

• Application of a novel light sheet microscopy system.
• Development of a specialized protocol for mounting Arabidopsis roots.
• Implementation of an automated root tip tracking system without proprietary software.

Main Results:

• Successful adaptation of light sheet microscopy for Arabidopsis root imaging.
• Establishment of a robust sample mounting and tracking protocol.
• Demonstration of the system's utility for studying root regeneration after laser ablation.

Conclusions:

• The presented methods improve compatibility of light sheet microscopy with plant samples.
• This work facilitates long-term time-lapse imaging of Arabidopsis root development.
• The accessible protocol can advance plant cell and developmental biology research.
