Abstract

mutantes de hemaglutinina do vírus influenza. a presente invenção refere-se à produção de proteínas virais de influenza modificadas em plantas. mais especificamente, a presente invenção se refere à produção e aumento da produção de partículas semelhantes ao vírus da gripe (vlp) em plantas, em que as vlps compreendem as proteínas virais da gripe modificadas, como a hemaglutinina da gripe modificada (ha). a proteína ha pode compreender uma sequência de aminoácidos compreendendo pelo menos uma substituição quando comparada a uma sequência de aminoácidos de tipo selvagem correspondente. além disso, são fornecidos ácidos nucleicos que codificam a proteína ha modificada. além disso, métodos de produção de uma partícula semelhante ao vírus da influenza (vlp) e métodos de aumento do rendimento de produção de uma partícula semelhante ao vírus da influenza (vlp) em uma planta, porção de uma planta ou célula vegetal também são fornecidos.
