When mutated Arabidopsis thaliana eIF4E and eIF(iso)4E were tested for susceptibility to Clover yellow vein virus (ClYVV) and Turnip mosaic virus (TuMV), eIF4E was shown to be necessary for infection by ClYVV but not for TuMV, while eIF(iso)4E was in contrast [26]. Here, EIF4E is linked to infection.
