Abstract

Se proporcionan composiciones y métodos que comprenden polinucleótidos y polipéptidos que tienen actividad de EPSP (5-enolpiruvilshikimato-3-fosfato) sintasa (EPSPS). En realizaciones específicas, la secuencia tiene una propiedad mejorada, tal como, pero no limitada a, capacidad catalítica mejorada en la presencia del inhibidor, glifosato. Adicionalmente se proporcionan construcciones de ácido nucleico, plantas, células vegetales, explantes, semillas y granos que tienen las secuencias de EPSPS. Se proporcionan diversos métodos para emplear las secuencias de EPSPS. Dichos métodos incluyen métodos para producir una planta tolerante a glifosato, célula vegetal, explante o semilla y métodos para controlar malezas en un campo que contiene un cultivo que emplea las plantas y/o semillas divulgadas en este documento. Reivindicación 1: Un polinucleótido que codifica un polipéptido de EPSP sintasa de planta (EPSPS), en el que el polipéptido de EPSPS de planta comprende G102A y por lo menos una o más mutaciones de aminoácidos seleccionadas del grupo que consiste en A2R, A2S, G3K, A4W, S38A, H54L, H54G, A69H, K71E, K84R, E92G, L98C, N162R, I208L, R216V, K224R, E226Y, K243L, K243E, M293L, K297A, E302P, V333A, A354G, T361S, R368C, E391P, R429A, D402G y A416G, en el que cada posición de mutación de aminoácido corresponde a la posición de aminoácido establecida en la SEQ ID Nº 1 y en la que el polipéptido de EPSPS de planta comprende una secuencia de aminoácidos que es por lo menos 90% idéntica a la SEQ ID Nº 2.
