Identification of Functional Domain(s) of Fibrillarin Interacted with p2 of Rice stripe virus
p2 colocalizes with the three functional domains of NbFib2 in the leaves of N. benthamiana. (a) p2-CFP was coexpressed with NbFib2-1-YFP. (b) p2-CFP was coexpressed with NbFib2-2-YFP. (c) p2-CFP was coexpressed with NbFib2-3-YFP. The nucleus was stained with 4′,6-diamidino-2-phenylindole (DAPI). Possible nucleolus and cajal body described in the text are designated with red and blue arrows, respectively. Fluorescence was observed at 48 h postinfiltration. Scale bars, 10 μm.
