SWO1 interacts with importin ɑ IMPA1 and IMPA2. (a) Mass spectrometric analysis of SWO1-interacting proteins. The co-purified proteins, including IMPA1, IMPA2, IMPA4, MOS6, KPNB1, and XPO1A are listed. NA means that the corresponding protein was not identified in the IP-MS data. (b) Split luciferase complementation assay was performed in N. Benthamiana leaves. The combinations of the indicated plasmids were co-transformed to N. Benthamiana leaves through Agrobacterium infiltration. Luciferase activity was determined 48 h after infiltration. nLUC represents the N-terminal fragment of firefly luciferase; cLUC represents the C-terminal fragment of firefly luciferase. (c) Mass spectrometry analysis of the proteins co-purified with IMPA1 and IMPA2. The SWO1 that was co-purified with IMPA1 and IMPA2 is shown. NA means that the corresponding protein was not identified in the IP-MS data
