Abstract

Composiciones y métodos para suprimir la respuesta de evitacion de sombra en plantas y para mejorar el rendimiento de las mismas. Las composiciones de la presente incluyen un gen de floracion temprana 3 (ELF3) de maíz, el promotor de este gen, un factor de transcripcion de hélice-bucle-hélice básico de Arabidopsis (bHLH-041). y fragmentos y variantes de los mismos. La secuencia promotora ELF3 es de utilidad para dirigir la expresion de los polinucleotidos de interés en una planta. Las secuencias ELF3 y bHLH-041 de la presente, o variantes y fragmentos de las mismas, se proveen en casetes de expresion para poder manipular la expresion de los genes ELF3 y bHLH-041. Al incrementar la expresion de ELF3 y/o suprimir la expresion de bHLH-041 los métodos de la solicitud proporcionan una respuesta alterada en plantas a la calidad de la luz y la supresion de la modalidad de desarrollo producida por una gran densidad. De esta manera, se provee métodos para cultivar plantas de cultivo con grandes densidades de poblacion a fin de mejorar el rendimiento de las mismas. Se proveen también plantas transformadas con el fenotipo de evitacion de sombra alterado de la presente y las semillas de dichas plantas. Reivindicacion 1: Un método para mejorar el rendimiento de una planta cultivada bajo condiciones de gran densidad de poblacion, caracterizado porque comprende: a) transformar una célula vegetal con una construccion que comprende un polinucleotido ELF 3, (gen de floracion temprana); y b) regenerar una planta a partir de dicha célula transformada en donde la expresion del polipéptido codificado por el polinucleotido ELF3 es mayor en la planta regenerada, o su progenie transformado, con relacion a la expresion en una planta control.
