Subcellular Localization of PHO1.
(A) Analyses of subcellular localization of PHO1-YFP (35S:gPHO1insYFP) using the ER, Golgi, trans-Golgi network (TGN), and endosomal markers in Arabidopsis protoplasts. Bars = 10 μm.
(B) Cellular and subcellular localization of PHO1-YFP (PHO1pro:gPHO1insYFP) in the Arabidopsis roots of a 5-d-old wild-type transgenic seedling under +Pi conditions. Bars = 20 µm.
(C) The majority of PHO1 is detected in the EM-enriched fraction. PIP1;1/2/3 and PHF1 are used as PM- and EM-localized markers, respectively. The bottom panel shows the protein staining on the membrane. WT, the wild type.
