Hyperosmotic stress induced actin filaments varying in Arabidopsis thaliana suspension cells

摘要

With the suspension cells of Arabidopsis thaliana stably expressing the GFP-fimbrin1 fusion protein and confocal microscope, the actin filaments distribution of single cell was investigated in real-time during hyperosmotic exposure. Our study suggested that the maintenance and recovery of normal cell volume is related with actin cytoskeleton, and the reorganization of AFs is following the shrinkage of plasmalemma during plasmolytic process.
