Abstract

La presente divulga un método para obtener arroz resistente al glifosato por una sustitución de nucleótidos dirigida al sitio, y también se refiere a un método capaz de generar una sustitución de nucleótidos dirigida al sitio y una sustitución de fragmentos. El método para obtener una planta resistente al glifosato proporcionado por la presente comprende los siguientes pasos: sustituir solo la treonina (T) en la posición 8 de la secuencia de aminoácidos de una región conservada de la proteína EPSPS endógena de una planta blanco con isoleucina (I), y sustituir la prolina (P) en la posición 12 con serina (S) para obtener una planta, es decir, una planta resistente al glifosato. El método proporcionado por la presente es de gran importancia en la obtención de variedades de plantas resistentes a los herbicidas. La presente también divulga un método para utilizar una vía NHEJ mediada por CRISPR para sustituir una región entre dos sitios de ARNg mediante el diseño de los dos sitios de ARNg, con lo cual se realiza una mutación dirigida al sitio de un nucleótido blanco y la sustitución dirigida al sitio de un fragmento.
