Abstract: 

During the past decade the use of live cytoskeletal probes has increased
dramatically due to the introduction of the green
fluorescent protein. However, to make full use of these live
cell reporters it is necessary to implement simple methods to
maintain plant specimens in optimal growing conditions during
imaging. To image the cytoskeleton in living Arabidopsis root
cells, we rely on a system involving coverslips coated with
nutrient supplemented agar where the seeds are directly germinated.
This coverslip system can be conveniently transferred to the
stage of a confocal microscope with minimal disturbance to the
growth of the seedling. Parallel to our live cell imaging
approaches, we routinely process fixed plant material via indirect
immunofluorescence. For these methods we typically use
nonembedded vibratome-sectioned and whole mount permeabilized root
tissue. The clearly defined developmental regions of the root
provide us with an elegant system to further understand the
cytoskeletal basis of plant development.
