High-amylose starch is in great demand by the starch industry for its unique functional properties. However, very few high-amylose crop varieties are commercially available. In this paper we describe the generation of very-high-amylose potato starch by genetic modification. We achieved this by simultaneously inhibiting two isoforms of
starch branching enzyme
to below 1% of the wild-type activities. Starch granule morphology and composition were noticeably altered. Normal, high-molecular-weight amylopectin was absent, whereas the amylose content was increased to levels comparable to the highest commercially available maize starches. In addition, the
phosphorus
content of the starch was increased more than fivefold. This unique starch, with its high amylose, low amylopectin, and high
phosphorus
levels, offers novel properties for food and industrial applications.
