Cytrap Marker Systems for In Vivo Visualization of Cell Cycle Progression in Arabidopsis

This chapter focuses on visualization of cell cycle progression in plant tissues using the dual-color marker system “Cytrap.” The Cytrap line carries a part of Arabidopsis CDT1a fused to the red fluorescent protein (RFP) gene, which monitors the cell cycle phases from S to late G2 or early mitosis, and the G2/M-specific cyclin B1 marker fused to the green fluorescent protein (GFP) gene. We introduce growth conditions of Arabidopsis roots, the setup for microscopic observation, and analysis of obtained images.
