SLC7A3 and infection: To investigate whether CAT1, CAT3, or HCPro could alter ChiVMV infection, overexpressing transgenic lines of CAT1, CAT3 (CAT1-OX and CAT3-OX), and HCPro-OX, and knockout transgenic lines of cat1, cat3, and double cat1cat3 (cat1-KO, cat3-KO, and cat1cat3-KO) were generated (Supplementary Figs S4, S5).
