Flax plants were transformed with a vector construct bearing expression cassette with two FAD2 gene (coding for type 2 fatty acids desaturase) segments modified in a way to employ RNA interference system for suppression of desaturase function, and due to it to increase the content of oleic acid in linseed oil.
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.
Linum usitatissimum - Flax, Flax, Linseed, LINUS
Characteristics of the transformation process
pPCV812i/35S/FAD2i/35S/GUS (FAD2-i GUS)
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.
Hygromycin B phosphotransferase gene - Escherichia coli - ECOLX
Resistance to antibiotics - Hygromycin
Selectable marker genes and reporter genes
Beta-glucuronidase coding sequence - Escherichia coli - ECOLX
Selectable marker genes and reporter genes
Fatty Acid Desaturase 2 - Linum usitatissimum - Flax, Flax, Linseed, LINUS
Changes in quality and/or metabolite content - Lipid and fatty acids
CaMV 35S promoter - Cauliflower mosaic virus - CaMV
Beta-lactamase gene - Escherichia coli - ECOLX
Resistance to antibiotics - Ampicillin
Notes regarding the genetic elements introduced or modified in this LMO
The inserted plasmid construct contains the FAD2-i expression cassette (the CaMV 35S promoter, DNA segment for desaturase, spacer, inverted DNA segment), CaMV 35S promoter from pAN4 plasmid, hpt gene from E. Coli, uidA gene for beta-glucuronidase (GUS) together with E.coli intron (K12) and AmpR gene for plasmid selection in bacteria.

Along with modified FAD2 gene the insert contains hpt selectable gene to enable selection of transgenic plants, uidA (GUS) reporter gene and AmpR gene to support plasmid construct selection in bacteria.
