IbPsbP interacts with IbOr. (A) Bimolecular fluorescence complementation (BiFC) assays for in planta interaction of IbPsbP with IbOr in chloroplasts. N. benthamiana leaves were transformed by Agrobacterium harboring N-terminal region of Venus (NV) and C-terminal region of Venus (CV) construct pairs and observed by confocal laser scanning microscopy. BR, bright field microscopy images; CHL, chlorophyll autofluorescence; VENUS, Venus fluorescence images; MERGE, overlay of bright field, chlorophyll, and Venus images. Scale bar = 20 μm. (B) Pull-down assay for in vitro interaction of IbOr with IbPsbP. Gels containing pull-down assay products were immunoblotted with anti-His. His-IbOr, GST (negative control), and GST-IbPsbP proteins are shown in the indicated combinations.
