Interactions between plant and virus proteins play pivotal roles in many processes during the viral infection cycle. Analysis of protein-protein interactions is crucial for understanding virus and host protein functions and the molecular mechanisms underlying viral infection. Several interactions between virus-encoded proteins have been reported. However, few interactions between viral and plant proteins have been identified so far. To examine interactions between Turnip mosaic potyvirus (TuMV) proteins and plant proteins, recombinant proteins were produced and used in ELISA-type assays and in in vitro co-immunoprecipitation experiments. An interaction between TuMV P1 proteinase and wheat poly(A)-binding protein (PABP) was identified. An interaction between P1 protein and the plant Arabidopsis thaliana eukaryotic initiation factor (iso)4E [eIF(iso)4E] was also found. Finally, potential interactions between both TuMV CI and P1 proteins and between TuMV CI protein and eIF(iso)4E were identified.
