Expression and protein localization pattern of SINE1 and SINE2 in trichomes and roots. (A) Expression and protein localization pattern of SINE1 in trichomes and roots. (B) Expression and protein localization pattern of SINE2 in trichomes and roots. Both genes are expressed in root cells, but only SINE2 is expressed in trichomes. Both proteins are localized at the NE. The trichome image of GFP-SINE1 was taken with 5× higher laser power (50%) than that used for GFP-SINE2, as indicated by the autofluorescence from the trichome cell wall. For the differentiated root cells, the nuclear surface was imaged to compare the fiber structure of GFP-SINE1 (outlined by dotted magenta lines in the overlay image) and relatively evenly distributed signal of GFP-SINE2. Bars, 10 µm. Diff., differentiated; Undiff., undifferentiated.
