Colocalization of BOR1-GFP and endocytic markers upon high-B supply. (A) GFP (green) and FM4-64 (red) fluorescence in root tip cells of P35S:BOR1-GFP plants (line 18). The plants were grown on low-B media and treated with high-B media for 30 min with equal time of FM4-64 uptake. (B) GFP (green) and mRFP (red) fluorescence in root tip cells of the transgenic plants expressing BOR1-GFP and mRFP-Ara7. The plants were grown on low-B media and treated with high-B media for 30 min. The arrowheads indicate colabeled structures. (Scale bar, 10 μm.)
