Description
The genetically modified potatoes are less susceptible to late blight as a result of the introduction of one or three resistance genes stemming from wild relatives from the potato. All three resistance genes belong to the NBS-LRR class, which code for a class of proteins that are common in plants and are involved in disease resistance.

In addition, these potato lines contain the nptII gene for resistance against the antibiotic Kanamycin.
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.
Solanum tuberosum - Potato, SOLTU
Characteristics of the transformation process
Vector
Agrobacterium Ti plasmid
Techniques used for the modification
  • Agrobacterium-mediated DNA transfer
Introduced or modified genetic elements
Some of these genetic elements may be present as fragments or truncated forms. Please see notes below, where applicable.
Phytophthora infestans Resistance gene 1 - Solanum stoloniferum - Wild potato
Resistance to diseases and pests - Fungi
Phytophthora infestans Resistance gene 1 - Solanum venturii - Wild Potato, SOLVN
Resistance to diseases and pests - Fungi
Phytophthora infestans Resistance gene 3 - Solanum bulbocastaneum - Nightshade, Ornamental nightshade
Resistance to diseases and pests - Fungi
Nopaline Synthase Gene Promoter - Agrobacterium tumefaciens - Agrobacterium, Rhizobium, RHIRD
Neomycin Phosphotransferase II - Escherichia coli - ECOLX
Resistance to antibiotics - Kanamycin
Nopaline Synthase Gene Terminator - Agrobacterium tumefaciens - Agrobacterium, Rhizobium, RHIRD
Notes regarding the genetic elements introduced or modified in this LMO
The region to be inserted, which is flanked by the T-DNA borders from the Ti-plasmid of Agrobacterium tumefaciens contains either:

- One resistance gene (Rpi-vnt1, stemming from solanum venturii)

- One resistance gene and a antibiotic resistance gene as selection marker  (Rpi-sto1 + nptII, stemming from solanum stoloniferum and from Tn5 respectively)

- Three resistance genes and a selection marker gene (Rpi-vnt1 + Rpi-sto1 + Rpi-blb3 + nptII, stemming from solanum venturii)

All three Rpi-genes involved are under the control of their own promoters and terminators.

The npt-II gene expression is driven by the NOS promoter and terminator. The npt-II gene stems from the transposon Tn5. The NOS promoter and terminator originate from Agrobacterium tumefaciens.
