Potato plant was modified with the insertion of a constitutively expressed partial sequence of the gene coding for a cytosolic starch phosphorylase from Solanum tuberosum in an antisense orientation.
Phosphorylases catalyse the reversible phosphorolysis of terminal glucose units of alpha-1,4-glucans and can therefore synthesis or degrade glucans depending on the concentration of inorganic phosphate and glucose-1-phosphate. This modification is intended to lead to an increase in tuber yield.
As a result of the genetic modification transgenic potato plants show an increased number of mature buds and produced more stems after having been stored at 20°C, with the underlying mechanism not being clear. The tuber yield is increased by 10-25%.

The term “Recipient organism” refers to an organism (either already modified or non-modified) that was subjected to genetic modification, whereas “Parental organisms” refers to those that were involved in cross breeding or cell fusion.

This deliberate release was proposed by Hoechst Schering AgrEvo GmbH.
AgrEvo GmbH, a company owned by Hoechst AG and Schering AG, merged with Rhône-Poulenc to become Aventis CropScience in 1999. This then merged with Bayer to become Bayer CropScience in 2001.
Therefore, Bayer CropScience is the contact point for questions regarding this deliberate release.
