Outline of Final Research Achievements |
Using affinity purification and mass spectrometry, we have identified a host protein GAPDH-A from Nicotiana benthamiana plants as the interacting partner of the movement protein (MP) of Red clover necrotic mosaic virus (RCNMV). GAPDH-A colocalized with virus replication complex (VRC) of RCNMV on the endoplasmic reticulum. We revealed that GAPDH-A is the host factor protein that contributes to the viral cell-to-cell movement, through its function to recruit the MP to VRCs. Furthermore, we showed the cortical punctate structures that contain the MP and VRC are required for the viral cell-to-cell movement and are not required for the replication of viral genomic RNA.
