Abstract

Un método para mejorar las características de almacenamiento en frío de un tubérculo de papa, que comprende:Reducir el nivel de actividad en los tubérculos de una enzima glucano fosforilasa seleccionada entre el grupo que consiste en fosforilasa de tubérculo tipo L de glucano (GLTP) y glucano fosforilasa tipo H (GHTP).El método de acuerdo con la reivindicación 1, que comprende:Introducir en la planta de papa un casette de expresión que tiene una secuencia promotora vegetal operativamente ligada a una secuencia de ADN que, cuando se transcribe en la planta, inhibe la expresión de un gen de glucano fosforilasa endógeno seleccionado entre el grupo que consiste en un gen de GLTP y un gen de GHTP.A method to improve the cold storage characteristics of a potato tuber, comprising: Reducing the level of activity in the tubers of a glucan phosphorylase enzyme selected from the group consisting of glucan L-type tuber phosphorylase (GLTP) and glucan phosphorylase type H (GHTP). The method according to claim 1, comprising: Introducing into the potato plant an expression cassette having a plant promoter sequence operatively linked to a DNA sequence that, when transcribed into the plant inhibits the expression of an endogenous glucan phosphorylase gene selected from the group consisting of a GLTP gene and a GHTP gene.
