Method for improving caracterìsticas cold storage of potato tuber

摘要

"Method for improvement of caracteru00ecsticas cold storage of the tuber of potato.Potato plants are provided with tubers with reduced level of phosphorylase alpha glucan type L (GLTP) or alpha glucan phosphorylase type - h for its enzymatic activity.The conversion of amu00eddo for sugar in potato tubers, particularly when stored at temperatures below - 7 u00b0 C,It is reduced in tubers processed with reduced enzyme activity to GLTP or ghtp.To reduce the au00e7ucaramento induced by cold in potatoes subject to storage at lower temperatures, resulting in prolonged dormancy, reduced incidence of disease.And the increase in the lifetime of storage.Methods for the production of potato plants that produce tubers with reduced enzyme activity in GLTP or ghtp may be supplemented by techniques such as suppression of the expression of GEne using RNA hu00f3mologo non oriented, the use of CO suppression, sequ00b3u00eancias regulatory silenciadoras, chemical inhibition and protein.Or the use of the mutagenic sites directed or isolation of species altrantivos to obtain variants of GLTP or ghtp with affinity or activity of starch decreased.
