Characterization of antigenic epitopes of potato virus Y.
Immunochemical analysis of overlapping synthetic hexapeptides covering the entire length of the coat protein of potato virus Y (PVY) revealed immunodominant regions both at the N-terminal and at the C-terminal end of the coat protein. Immunization of rabbits with synthetic peptides representing N- and C-terminal regions of the coat protein resulted in production of antibodies that reacted with PVY. Antigenicity of PVY peptides was found to correlate with predicted beta turns, with hydrophilicity and with predicted chain flexibility. Characterization of the immunochemical properties of PVY will facilitate the development of detection methods for potyviruses.
