Next, co-immunoprecipitation mass spectrometry (Co-IP MS), RNA sequencing (RNA-seq), luciferase complementation assay (LCA), bimolecular fluorescence complementation (BiFC), and fluorescence recovery after photobleaching (FRAP) were applied to investigate the underlying mechanisms of infection diversity between GFP-PMMoV CP and GFP-PMMoV CP<sup>Y13A</sup>. The gene discussed is CP; the disease is infection.
