Light and G Protein Coordinate Regulation of Arabidopsis Photomorphogenic

Seeds were germinated on 1/2 MS plates plus 1% sucrose and placed at 4°C for 3 days and then transferred to white light for 12 h before placed in blue light for another 4 days. Total RNA was extracted from samples including WT, agb1, cry1 cry2 and hy5 with RNAprep plant kit (TIANGEN), and followed by DNase I (Takara) treatment. This study reveals the molecular basis for light and G-protein crosstalk by analyzing gene expression profile under control of both signals.
