Acido ribonucleico aislado silenciador; polinucleotido que lo codifica; metodo de fabricacion; y metodos para modular la expresion de un gen diana en un organismo hospedero, para proteger un organismo hospedero contra un parasito o patogeno y para controlar plagas que se alimentan de plantas.

摘要

The present invention relates to the genetic control of parasites and pathogens via the expression of silencing RNA in transgenic plants, including microalgae. In one aspect, the invention exploits the ability of plants to express the silencing RNA in a form within chloroplasts that is efficiently taken up, after ingestion where it can act to suppress the expression of target genes within the pathogen or parasite.
