Subcellular localization of PdBG2 after SL inhibitor treatment in Arabidopsis hypocotyls. Confocal images show Arabidopsis hypocotyls expressing fluorescent fusion protein of PdBG2 after SL inhibitor treatment (24 h) as follows: mock (A), 0.1 μm myriocin (B), 5 μm FB1 (C), 50 μm PDMP (D), 40 μm D609 (E), and 30 μm DMS (F). White arrows indicate GFP:PdBG2 localizations. Red signals show propidium iodide staining of the cell wall. Bars = 20 μm.
