Expression pattern of OsCd1 in rice. a Tissue-dependent expression of OsCd1 at vegetative stage. Left: GUS histochemical assay of the transgenic plant with the GUS reporter driven by the OsCd1 promoter. Right: the expression level of OsCd1 in root and shoot with and without 1 μM CdCl2 treatment via qPCR. Bars = 2 mm. b Tissue-specific localization of OsCd1 in the root of rice using the GUS reporter driven by the OsCd1 promoter. Bars = 0.5 mm. c Tissue-specific localization of OsCd1 in the root of rice using the GFP driven by the OsCd1 promoter in cross frozen sections. Nip, negative control; Ubi::GFP, positive control. Bars = 10 μm. d The GFP transcriptional level shown by RT-PCR. Upper, GFP; Down, Actin. e Subcellular location of OsCd1 in the root of rice observed by confocal laser scanning microscopy. The GFP fluorescence, fluorescence of FM4-64 and overlay of FM4-64 and pMDC45-GFP (left), OsCd1-GFP (right) were shown, respectively. Bars = 20 μm. f Subcellular location of OsCd1 in root protoplasts. Bars = 10 μm. Source data of Fig. 3a and d are provided as a Source Data file
