Figure 4. Workflow of the SMV-based gene delivery for identification of cellular interacting protein partners.

Figure 4

Schematic representation of SMV recombinant constructs shows in-frame insertion of the Flag-tagged GFP and Flag-tagged HC-Pro into the P1/HC-Pro gene insertion cassette of pSMV-Dual vectors. Each SMV recombinant construct was rub-inoculated on the leaves of soybean seedlings. At 15 dpi, crude plant extracts prepared by homogenizing the upper symptomatic leaves were subjected to immunoprecipitation using anti-Flag antibody-conjugated agarose beads. The resulting co-immunoprecipitated products were analyzed by SDS-PAGE and the bands of interest (indicated by asterisks) were excised from the gel and subjected to LC-MS/MS analysis. The identified proteins and MS/MS spectral information are shown.
