Potato modified for increased tuber yield

No
Potato plant was modified with the insertion of a gene coding for a proton ATPase deltaPHA2 from Solanum tuberosum which is specifically expressed in the companion cells.

The modification is expected to lead to increased tuber yield through the actions of deltaPHA2 would lead to increased loading of the phloem with photoassimilates.

As a result of the genetic modification the tuber yield of the transgenic potato plants is increased by 10-20%.

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.

Additional Information
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.
