Abstract

To search for host proteins involved in systemic spreading of Tomato spotted wilt virus (TSWV), the virus-encoded NSm movement protein has been utilized as a bait in yeast two-hybrid interaction trap assays. J-domain chaperones from different host species and a protein denominated At-4/1 from Arabidopsis thaliana showing homologies to myosins and kinesins were identified as NSm-interacting partners. In this communication we illustrate that following TSWV infection, J-domain proteins accumulated in systemically infected leaves of A. thaliana, whereas At-4/1 was constitutively detected in leaves of A. thaliana and Nicotiana rustica.
