Characterization of cucumber mosaic virus. III. Localization of sequences in the movement protein controlling systemic infection in cucurbits.

abstract：:When hemagglutinin (HA) and neuraminidase (NA) are presented together on an intact influenza virus particle, the antigens are competitive, with HA dominant over NA in T- and B-cell priming. Immunization with mixtures of purified HA and NA eliminates antigenic competition between HA and NA, as well as between N1-N2 NA ...
