Abstract

Disclosed is a method of producing altered starch from transformed potato plants or their progeny, comprising extracting starch from a potato plant, at least the tubers of which comprise at least an effective portion of a starch branching enzyme (SBE) cDNA sequence operably linked in the antisense orientation to a suitable promoter, such that the level of SBE activity is limited to less than 0.8 units per gram tuber. Also disclosed are potato plants comprising altered starch in accordance with the invention.
