Resistance to the fungus Venturia inaequalis, causative agent of the disease called apple scab, is the trait that was introduced. No further marker or other genes are present.
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.
Malus domestica - Apple, MALDO

Characteristics of the transformation process
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.
Homologues of Cladosporium fulvum Resistance genes of the Vf region - Malus domestica - Apple, MALDO
Resistance to diseases and pests - Fungi
Notes regarding the genetic elements introduced or modified in this LMO
The recombinase located on the pMF1 backbone can be activated by adding dexamethason resulting in the excision of the vector backbone. As a result of this excision only the intended trait will be present in the LMO.

Three distinct constructs were generated:
SPVf2: RB --> Native HcrVf2 gene promoter --> Hcr2Vf2 coding region --> Native HcrVf2 gene terminator --> LB
CH12: RB --> Native HcrVf2 gene promoter --> Hcr2Vf2 coding region --> Native HcrVf2 gene terminator --> LB
RbcVf2: RB --> Apple Rubisco promoter --> HcrVf2 --> Apple Rubisco Terminator --> LB
