SMG7 and viral infectious disease: For example, ATG8f interacts with CLCuMuV βC1;[23] ATG6 interacts with TuMV NIb, CGMMV RdRP and PepMV RdRp;[25] ATG8i interacts with the C1 protein of TLCYnV.[6] In this study, we found that viral infection decreased the protein accumulation of SMG7 (Figure 4B; Figure S9, Supporting Information).
