The Rpi-blb1 and Rpi-blb2 genes inserted in these genetically modified potatoes should confer increased resistance to Phytophthora infestans. Rpi-blb1 and Rpi-blb2 code for proteins of the NBS-LRR (nucleotide binding site-leucine rich repeat) type.

The ahas gene inserted in the potato plants imparts tolerance to the herbicidal active substance Imazamox to the shoots during the selection process in cell culture.
Recipient Organism or Parental Organisms
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
Observed gene expression in the transgenic plants

In the genetically modified lines a low level of expression of both Rpi-blb1 and Rpi-blb2 has been demonstrated by real-time PCR analysis in leaves, stems, tubers and roots. In flowers a low expression of Rpi-blb2 can be detected, while Rpi-blb1 is expressed at even lower levels or not at all.
The ahas gene is controlled by the nos promoter, which is known to result in low expression levels in all parts of the plant. Expression of the ahas gene in the genetically modified potato material has been demonstrated in tissue culture by survival on media containing Imazamox.
