What is the main advantage of this imaging technique?
It allows for the dynamic observation of protein movements during cell division and differentiation, unlike static imaging methods.
How are the cotyledons prepared for imaging?
The seed coat is removed, and cotyledons are immobilized under agar media for clear visualization.
What type of proteins can be tracked using this method?
Fluorophore-tagged proteins can be tracked to study their localization and expression during development.
How long does the imaging process take?
Time-lapse imaging is performed over several days to capture the growth and division of epidermal cells.
What plant species is used in this study?
The study uses Arabidopsis seeds for the experiments.
Can this method be applied to other plant species?
Yes, the protocol can potentially be adapted for other plant developmental studies.
