Yeast two-hybrid study of tobacco rattle virus coat protein and 2b protein interactions

Yeast two-hybrid study of tobacco rattle virus coat protein and 2b protein interactions The specificity of the interaction between the coat protein (CP) and 2b nematode-transmission helper protein of two isolates, PpK20 and PaY4, of Tobacco rattle virus (TRV) that differ in their transmission characteristics was investigated. Yeast two-hybrid experiments identified a central domain of the CP that promoted CP:CP interaction but inhibited CP:2b interaction. Deletion of a conserved coiled-coil domain from the 2b protein prevented its interaction with CP, whereas deletion of N- and C-terminal domains of the 2b protein greatly enhanced its interaction with CP. A C-terminal flexible domain of the CP was also shown to be important for interaction with the 2b protein. However, this domain was not sufficient to direct isolate-specific interaction of these proteins either in yeast or via a chimeric TRV in planta . Although these two TRV isolates are both transmitted by a shared vector trichodorid nematode, Paratrichodorus pachydermus , the CP from isolate PpK20 did not interact with the 2b protein from isolate PaY4, and vice versa , suggesting that in the field mixed infections of TRV are unlikely to cause promiscuous transmission by alternative trichodorid nematode species. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Archives of Virology Springer Journals
