Abstract

La presente invención se refiere a la producción de proteínas virales de influenza modificadas en plantas. Más específicamente, la presente invención se refiere a producir y aumentar la producción de partículas similares al virus de la influenza (PSV) en plantas, en donde las PSV comprenden las proteínas virales de la influenza modificadas, tales como hemaglutinina (HA) de la influenza modificada. La proteína HA puede comprender una secuencia de aminoácidos que comprende por lo menos una sustitución en comparación con una secuencia de aminoácidos de tipo salvaje correspondiente. Se proporcionan además ácidos nucleicos que codifican la proteína HA modificada. Además, también se proporcionan métodos para producir una partícula similar al virus de la influenza (PSV) y métodos para aumentar el rendimiento de producción de una partícula similar al virus de la influenza (PSV) en una planta, porción de una planta o célula de una plantal.
