研究了编码真核细胞起始因子(EIF4E)或eIF4E亚型(eIF(Iso)4E)基因突变的拟南芥植株对马铃薯Y病毒属三叶草黄脉病毒(ClYVV)的敏感性。在缺乏eIF(Iso)4E的突变株中，接种和未接种的叶片中都积累了ClYVV，但在缺乏eIF4E的突变株中没有积累。相反，马铃薯Y病毒属的另一成员芜菁花叶病毒(TuMV)在缺乏eIF4E的突变株中繁殖，但在缺乏eIF(Iso)4E的突变株中不繁殖。这些结果表明，eIF4E家族的成员选择性地参与了马铃薯Y病毒的感染。
Arabidopsis thaliana plants with mutations in the genes encoding eukaryotic initiation factor (eIF4E) or isoform of eIF4E (eIF(iso)4E) were tested for susceptibility to Clover yellow vein virus (ClYVV), a member of the genus Potyvirus. ClYVV accumulated in both inoculated and upper uninoculated leaves of mutant plants lacking eIF(iso)4E, but not in mutant plants lacking eIF4E. In contrast, Turnip mosaic virus (TuMV), another member of the genus Potyvirus, multiplied in mutant plants lacking eIF4E but not in mutant plants lacking eIF(iso)4E. These results suggest the selective involvement of members of the eIF4E family in infection by potyviruses.
