Outline of Final Research Achievements |
We analyzed the molecular mechanism by which Cucumber mosaic virus (CMV) induces necrosis on inoculated leaves of Arabidopsis. We could show direct evidence of the protein-protein interaction between the 2b protein of CMV (2b) and host catalase (Cat3). The stability of the 2b-Cat3 complex seems to be regulated by cellular proteasome; the more stable the complex is, the more rapidly it is degraded. For the host plant, Cat3 may function as an anti-CMV factor that can interfere with the function of 2b.
