METHOD OF IMPROVING THE QUALITY OF STORED POTATOES

摘要

A method of improving the quality of potatoes stored at reduced temperatures and a method of prolonging dormancy of stored potato tuber by increasing the level of ADPglucose pyrophosphorylase enzyme activity within the potato tuber during storage at ambient or reduced temperatures. Novel DNA molecules, plant cells, and potato plants are provided wherein the gene for the ADPglucose pyrophosphorylase enzyme is under the control of a cold-inducible promoter.
