Potato plants with a reduced activity of the cytosolic starch phosphorylase and an altered germination of the invention is to keep

摘要

The description relates to transgenic potato plants containing cells having a reduced cytosolic starch phosphorylasis activity in comparison with wild types of plant. By comparison with tubers of wild plant types, tubers of such potato plants exhibit a drastically altered germination behaviour, resulting in an increased number of sprout ends and hence of stolones and tubers. Plants from such tubers give higher yields.
